Google Maps has now released the amazing 8-bit edition. It comes complete with pictures of the country in 8-bit and a Slime who draws near! While Tantegel Castle does not appear on the map and you don’t seem to be able to find any Internet connectivity arising from King Lorik’s toilet, it is possible to find cute propeller headed icons where Google offices are as well as a number of landmarks that have been converted into 8-bit highlights showing people why they should visit your area. In fact, the landmarks themselves have been converted to 8-bit in order for you to be able to fully enjoy the country as it would have appeared in an NES quest, so if you visit the landmarks you’ll see that they’ve been temporarily replaced with 8-bit renditions of themselves. The proof is in the street view of each location. This was most difficult with some of the larger monuments, such as the Grand Canyon. But that’s OK, Google had a pretty good year (shares are well over $600 a pop still).
One thing to look out for though, are the monsters, such as this little bugger, which was a wizard and then a dragon, kinda’ like the witch from Sleeping Beauty. Which was fine in a game. But Google spared no expense with this new product. There is an actual dragon sitting in the middle of the Atlantic Ocean. Granted, it’s 8-bit, and really, all you get when you conquer the Dragonlord is a ball of light, which you can get at any medical marijuana spot in California if you claim to have stress. But it’s kinda’ weird ’cause he’s started shooting flames up at flights, which I hear has stirred up some new union disputes with American Airlines.
There’s also an 8-bit Santorum that Romney has been edging for awhile…
As with every April 1st, Google has also released a video on how to use their amazing new invention:
Note: For those of us who remember blowing on game cartridges to make them work, this is a very welcome addition to the Google repertoire. No matter how fleeting an addition it may be…
Finally, let’s hope that Gwaelin isn’t 8-bit. Let me know if you manage to rescue her from the Swamp Cave…

The built-in message hygiene in Lion Server is provided by Spam Assassin and clamav (amavis). Lion Server’s Server Admin application has an easy-to-use way of configuring some of the more basic settings for Spam Assassin. Spam Assassin’s rules are configured in /etc/mail/spamassassin/local.cf. If you open this into a standard text editor then you can insert blocks that are rules. Each rule has the ability to either locate text within a header (such as an email address), a subject or in the text of an email. To use Spam Assassin to block messages that have the word viagra in them, for example, you would insert the following block:
body NO_MORE_VIAGRA /viagra/i
score NO_MORE_VIAGRA 10
description NO_MORE_VIAGRA messages that contain the word Viagra
The first line looks for any email with the word viagra. The second line assigns it a score of 10 and the third gives us an easy to read description. You can also effectively whitelist email addresses or words. For example, the following would subtract 100 from the score of any email sent from my iCloud account:
header FROM_KRYPTED ALL =~ /firstname.lastname@example.org/i
score FROM_KRYPTED -100
description FROM_KRYPTED messages from krypted
The above block is similar to the previous one, but instead of adding to the likelihood that the message is spam we’re subtracting so much that even if I’m talking about viagra, the message still wouldn’t be flagged as spam.
Once you’ve entered the rules that you feel are needed for your environment, run the spam assassin command followed by the –lint option:

Apple Configurator has now been in my grubby hands long enough for me to start looking at it a little deeper than I did in the introductory article I did awhile back. Architecturally, Apple Configurator keeps its data in ~/Library/Application Support/com.apple.configurator. Here, you’ll find a directory called IPSWs, another called Resources, file called AppleConfigurator.storedata and another called Users.storedata.
The IPSWs directory is where operating system versions, per model of iOS are stored. These look something like iPad2,1_5.1_9B176_Restore.ipsw, which is iOS 5.1 for a standard iPad 2. iPad 1, the retina display iPad, as well as each iPod Touch and iPhone 4 each have their own entry as well. The IPSWs are automatically downloaded here when you initially perform a restore using Apple Configurator for each model of iOS device. You can copy each model’s ipsw into this directory proactively to keep Apple Configurator from downloading updates. You can also populate this directory manually with older copies of iOS if you are running them or if you are a developer, with developer releases of ipsw files.
The Resources directory is going to house applications and documents/content that you’ll be pushing to devices if you use the Assign options to assign content (and possibly other assets, although thus far I seem to only be getting apps and documents in here). They don’t look like applications or documents though. Each entry in this directory is assigned a generated identifier. The size of each and date/time stamp should match the size of the object and when it was added to Apple Configurator, respectively. When you delete an application or document from Apple Configurator then you should see the entries here disappear. Running strings against the entries that are applications, you should be able to identify which is which pretty quickly. Running such commands against documents (or other assigned content) can net much spottier results due to the fact that there aren’t always references to what you’re looking at inside of what you’re looking at… Either way, just looking at the raw data that comprises these application and content objects isn’t the only way to grab the name of the file. We’ll take a look at that a little later.
In addition to these two directories, Apple Configurator can throw data almost anywhere because it allows users to do so when creating backups of devices. These backups are in the form of files ending with .iosdevicebackup and by default getting placed into ~/Documents. When these are created, they can be saved to any location you choose. Deleting them from the file system automatically causes Apple Configurator to forget about them (although I have had to restart the application after removing the .iosdevicebackup file).
And then there’s the databases. As I mentioned, there are two, AppleConfigurator.storedata and Users.storedata. These are both sqlite databases and are both accessible through standard sqlite3 commands/queries. I haven’t been able to find any documentation of what each table is used for, but I’ve run devices through a number of regressions and think I’ve mostly pieced it together, which I’m in some cases able to back up with writing directly to the SQL table. Each database consists of the following tables (although not all are used and in some cases they are used for different purposes in each database), which I show followed by a description of what I think each is doing along with the more important columns of each table:
Now that we know roughly what’s where, let’s put that to use. Let’s start with just getting some information on what profiles are installed in Apple Configurator. Here, we can run a SQL select to look at all the rows in the ZPROFILE table, by calling the sqlite3 command (in /usr/bin), using the SQL table as our first position and then putting our select query in quotes, which in this case is to select all (*) information from the ZPROFILE table:
sqlite3 ~/Library/Application Support/com.apple.configurator/AppleConfigurator.storedata 'SELECT * FROM ZPROFILE'
To export a profile from Apple Configurator’s database using sqlite3 (which means you can do this from a centralized location), use the sqlite3 command, selecting the database and then run a select for the ZPROFILE table, selecting the ZNAME record called Pretendco Deployment and then send the output to a file called test.mobileconfig:
sqlite3 ~/Library/Application Support/com.apple.configurator/AppleConfigurator.storedata 'SELECT * FROM ZPROFILE WHERE ZNAME = "Pretendco Deployment"' > test.mobileconfig
Strip the first line of that file out and you’ve got yourself a mobileconfig file.
To see all of your applications:
sqlite3 ~/Library/Application Support/com.apple.configurator/AppleConfigurator.storedata 'SELECT * FROM ZMOBILEAPPLICATION'
Or if that’s too much output (it is), then just look at the names of the apps:
sqlite3 ~/Library/Application Support/com.apple.configurator/AppleConfigurator.storedata 'SELECT ZNAME FROM ZMOBILEAPPLICATION'
These are just a few light queries. You could easily expand on this to export all of the profiles as mobileconfigs, dump a list of each iOS device that has each app installed, a list of which users have which devices, which users have which apps, which devices are running low on disk space, etc. Overall, the sqlite queries are similar in nature (or can be) to what we were doing in the scripting iPhone Configuration Utility article I did awhile back; however, there are a lot more options here.

Profile Manager allows you to leave certain fields that are user-centric blank and it will prompt at the time that the profile is installed for the blank information. These are usually user-centric fields, such as short name and password. You can also create a profile in Profile Manager for each user you want to setup mail, Exchange, iCal, Address Book and other services that are tied to a specific user. You can enter the username for each and leave the password blank and the user will be prompted for the password but have the username filled in. And then there are payload variables.
Note: Before we get started on Payload Variables, it’s worth noting that many did not work well prior to 10.7.3, most notably %email%.
Profile Manager provides a number of ways to configure accounts and settings on iOS based devices. When a user logs in, the user’s name, email address, title, phone number and both the short name and GUID of the user’s account are able to be substituted using variables. These variables have a % in front of and behind the name of the variable, making them easy to identify when looking at accounts. These can easily be put into a profile’s payload. When a user logs in the contents of the payload variable are replaced with the information for the account that logged in using the /MyDevices page in the web enrollment interface. When the enrollment profile is downloaded to the device, the variable is substituted with the user’s information from directory services (for user payloads) or from the device itself (for device payloads).
Using payload variables is a really straight forward process. First, create a profile by logging into the Profile Manager web interface (the name of the server followed by /ProfileManager. When prompted, provide the username and password for an administrative account.
Click on a group or user who you would like to configure a profile for.
From the profile screen, select the payload that you’d like to configure.
Enter the variable into the field(s) you’d like the substitution to occur in. For example, here I’m using a variable everywhere currently possible.
Note: You can wrap the variable with other text. For example, if you enter krypton.com/%short_name% then for a user of cedge the variable would expand as krypton.com/cedge, useful in doing Exchange configurations.
Variables available for use include user and device variables. These user variables are as follows:
The device variables are as follow:

Spotlight doesn’t automatically index network volumes. To configure spotlight to index network volumes, use the mdutil command followed by an arbitrary path, with the -i option and then the on parameter. For example, for a volume called Galvatron, you would enable indexing using the following command:
mdutil /Volumes/Galvatron -i on
To monitor the status of the indexing process:
mdutil /Volumes/Galvatron -s
If this happens to cause any problems, use the off parameter instead, along with the same command to disable indexing of that volume.
mdutil /Volumes/Galvatron -i off
You can send the mdutil commands through Apple Remote Desktop. For example, I’ve needed to toggle indexing on and then off, for which I would do something as follows via ARD:
mdutil /Volumes/Galvatron -i off; mdutil /Volumes/Galvatron -i on

New in Lion Server, Profile Manager is the most substantial new service added to Mac OS X Server in recent memory. A lot of engineering has gone into it since the introduction in 10.7.0 and in 10.7.3, Profile Manager represents a service that is ready for actual deployments. I have written a number of articles about Profile Manager, but they all revolved around working with Profile Manager once the service is setup and configured. Therefore, I have decided to document the steps used to take a system out of the box and configure it for Profile Manager.
Before we get started, let’s prep the system for the service. This starts with configuring a static IP address and properly configuring a host name for the server. In this example, the IP address will be 192.168.210.75 and the hostname will be mdm.pretendco.com. We’ll also be using a self-signed certificate, although it’s easy enough to generate a CSR and install it ahead of time. For the purposes of this example, we have installed Server from the App Store (and done nothing else with Server except open it the first time so it downloads all of its components from the web) and configured the static IP address using the Network System Preferences. Next, we’ll set the hostname using scutil.
sudo scutil --set HostName mdm.pretendco.com
Then the ComputerName:
sudo scutil --set ComputerName mdm.pretendco.com
And finally, the LocalHostName:
sudo scutil --set LocalHostName mdm
Now check changeip:
sudo changeip -checkhostname
The changeip command should output something similar to the following:
Primary address = 192.168.210.75
Current HostName = mdm.pretendco.com
DNS HostName = mdm.pretendco.com
The names match. There is nothing to change.
dirserv:success = "success"
Provided the IP address and hostname are correct, then if you don’t see the success and that the names match, you might have some DNS work to do next, according to whether you will be hosting DNS on this server as well. If you will be hosting your own DNS on the Profile Manager server, then the server’s DNS setting should be set to the IP address of the Server. I have downloaded and installed the Server Admin Tools and then opened Server Admin, connected to the server and configured just the mdm server as a single record in the pretendco.com zone:
Provided your DNS looks just like this (your host name not mine) then changeip should work. If you’re hosting DNS on an Active Directory integrated DNS server or some other box then just make sure you have a forward and reverse record for the hostname/IP in question.
Now let’s open the Server app from the Applications directory. Here, use the Next Steps drawer at the bottom and verify that the Configure Network section reads that “Your network is configured properly” as can be seen here:
Profile Manager is built atop the web service, APNS and Open Directory. Therefore, let’s close the Next Steps drawer, click on the Web service and just hit start. We’re not going to configure anything else with this service in this article so as not to accidentally break Profile Manager. Do not click on anything while waiting for the service to start. While the indicator light can go away early, note that the Web service isn’t fully started until the path to the default website is shown instead of /var/empty (the correct entry, as seen here, should be /Library/Server/Web/Data/Sites/Default). If you touch anything too early then you’re gonna’ mess something up, so while I know it’s difficult to do so, be patient (honestly, it takes less than a minute, wait for it, wait for it, there!).
At the Directory Administrator screen, provide the username and password you’d like the Open Directory administrative account to have (note, this is going to be an Open Directory Master, so this example diradmin account will be used to authenticate to Workgroup Manager if we want to make changes to the Open Directory users, groups, computers or computer groups from there). Once you’re done entering the correct information, click Next.
At the Organization Information screen, enter your information (e.g. name of Organization and administrator’s email address). Keep in mind that this information will be in your certificate (and your CSR if you submit that for a non-self-signed certificate) that is used to protect both Profile Manager and Open Directory communications. Click Next.
At the Confirm Settings screen, make sure the information that will be used to configure Open Directory is setup correctly. Then click Set Up (as I’ve put a nifty red circle next to – although it probably doesn’t help you find it if it’s the only button, right?).
The Open Directory master is then created. Even if you’re tying this thing into something like Active Directory, this is going to be a necessary step. Once Open Directory is setup you will be prompted to provide an SSL Certificate.
This can be the certificate provided when Open Directory is initially configured, which is self-signed, or you can select a certificate that you have installed using a CSR from a 3rd party provider. At this point, if you’re using a 3rd party Code Signing certificate you will want to have installed it as well. Choose a certificate from the Certificate: drop-down list and then click on Next.
If using a self-signed certificate you will be prompted that the certificate isn’t signed by a 3rd party. Click Next if this is satisfactory.
You will then be prompted to enter the credentials for an Apple Push Notification Service (APNS) certificate. This can be any valid AppleID. It is best to use an institutional AppleID (e.g. email@example.com) rather than a private one (e.g. firstname.lastname@example.org). Once you have entered a valid AppleID username and password, click Next.
Provided everything is working, you’ll then be prompted that the system meets the Profile Manager requirements. Click on the Finish button to complete the assistant.
When the assistant closes, you will be back at the Profile Manager screen in the Server application. Here, check the box for Sign Configuration Profiles.
Unless you’re using a 3rd party certificate there should only be one certificate in the list. Choose it and then click on OK. If you are using a 3rd party certificate then you can import it here, using the Import… selection.
Now that everything you need is in place, click on the ON button to start the service and wait for it to finish starting.
The URL for this (for mdm.pretendco.com) is https://mdm.pretendco.com/profilemanager. Use the Everyone profile to automatically configure profiles for services installed on the server if you want them deployed to all users. Use custom created profiles for everything else.
Once enrolled, you can wipe or lock the device from the My Devices portal. Management profiles from the MDM server are then used. Devices can then opt out from management at any time. Saving these two profiles to a Mac OS X computer then allows you to automatically enroll devices into Profile Manager using Apple Configurator.

Mi Casa Verde has had the Vera appliance for a number of years. Recently, they released the Vera 3, which controls practically any Z-wave device ever made (in fact many are guaranteed to work). The Vera 3 is also wireless (802.11), so you can place it practically anywhere in the home.
Now there’s Vera Light, which retails for $100 less, has a much smaller footprint and no 802.11 networking but otherwise it appears to have pretty much the same feature set. I’m sure it can’t control as many things concurrently, given the smaller footprint, but it looks to me like a great deal for those looking to get started with Z-Wave and home automation in general!

My traditional interpretation of Apple’s vision on how iOS devices are used is that everyone has an AppleID. That AppleID enables them to access their apps from any iOS device they own or Mac that they own. That AppleID enables them to access mail, contacts, calendars and even files through iCloud. That AppleID also allows users to remotely wipe their device through Find iPhone and track their friends iOS devices (as in social networking via breadcrumb tracking) through Find Friends. All of this “Just Works” in a consumer sense. And it even allows for a little sharing of content across devices you own. However, larger organizations need more. They need centralized management, content distribution and most other things you find that you rely on traditional desktop computers for.
Over the years, Apple has added tools for centralized control of devices. This started with ActiveSync compatibility and early forms of Mobile Device Management and has grown into a pretty robust, albeit disconnected, set of tools. Of these, Apple Configurator is the latest. Apple Configurator was released about a week ago and since, I’ve been trying to figure where it fits into the solutions architecture that surrounds iOS integrations. There are a number of other tools already available that can aid in the deployment and management of iOS devices, and Configurator is a great addition.
To me, there are 3 classes of management tools for iOS. These were roughly broken up into Over the Air (OTA), cradled (USB) and content management. Apple Configurator ends up fitting into all of these scenarios in some way. Let’s start by looking at the traditional uses of these three and then look at how they are impacted by Apple Configurator.
Mobile Device Management
Over the Air tools, such as Profile Manager, allow for Mobile Device Management (MDM) without cradling, or syncing a devices. These tools allow you to configure policies via profiles. There is also a bit of App pushing built into most MDM solutions. Apple’s Profile Manager can push applications written in-house, but no content from the App Store. 3rd party solutions, such as JAMF’s Casper Suite, Absolute Manage MDM, AirWatch and about 15 others are able to push apps from the App Store as well, leveraging the Volume Purchasing Program (VPP) to issue apps to devices. However, when an app is pushed through one of these tools, the app becomes associated with the AppleID for the user who owns the device.
Note: While we use the term push, the user has to accept all App installations on the device.
For large environments, MDM is a must as it allows for centralized command and control. Pushing apps is one aspect of such control. Policies enforceable through MDM include disabling cameras, configuring passcode policies on devices (not pushing passcodes), disabling YouTube, silencing Siri, unstreaming photos, disabling iCloud Backup, forcing encrypted backups, disabling location services, controlling certificates, blocking pop-ups, controlling cookies, disabling access to the iTunes and App Stores, and controlling what kind of media can be accessed on devices.
Additionally, MDM can be used to push SSIDs for wireless networks (and their passwords/802.1x configuration information), setup mail, setup Exchange ActiveSync, configure VPN connections, configure access shared calendars (iCal shared files, CalDAV and Exchange), configure access to shared contacts (LDAP, CardDAV, Exchange and Exchange Global Address Lists), deploy Web Clips and manage certificates (either with cert files or via SCEP). In short, whether you’re using the practically free Profile Manager from Apple, Mobile Iron, Casper, AirWatch, FileWave or one of the many other tools, there are a lot of things that MDM can configure on devices.
Reporting can also play a major role in how MDM tools are used. iOS Apps are owned by AppleIDs, not devices. MDM does not manage AppleIDs, but you can trigger fields in MDM databases to report back unauthorized AppleIDs being used. Reporting can also identify when devices join non-approved wireless networks (which cannot be blocked through MDM), identify devices that have been jailbroken (a major security concern for many organizations) and report on device use.
Because devices can fall outside of our control, MDM also plays an important role in being able to wipe and lock devices. While some of these types of features are available via Exchange, not all people use ActiveSync. Users and administrators alike can wipe, lock and de-enroll devices at will, potentially crippling what any device with an Enrollment Profile can do.
There are really 3 kinds of MDM tools: those that can push apps, those that can’t and Apple’s Profile Manager. The reason I put Profile Manager into its own class, is that it can push some kinds of apps, it’s cheap ($49.99 one time as opposed to per device per month or per device per year billing) and it’s great for some things. But Profile Manager should be used in very specific environments unless the price is the only decision making factor behind a tool. In larger environments, choosing a MDM solution is one of the most important aspects of managing mobile devices and the iOS platform is no different in that manner than other mobile platforms.
MDM has some limitations, though. A good MDM solution can manage the infrastructure side of device configuration. However, content requires a completely separate tool. Additonally, MDM is a completely opt-in experience. If a user wants, they can remove their device from the MDM solution at any time. Rather than a limitation, think about the opt-in experience this way: if a user removes themselves from MDM then all content that was given to them via MDM is then taken away, except that which they have moved to the local device. Therefore, if an administrator pushes an Exchange configuration then all content from that Exchange profile is forbidden fruit, removed alongside the de-enrollment.
MDM also works with Lion. Policies, centralized management, etc can be integrated with Lion. You can’t do app distribution per se, but you can push out a policy to change where the dock is on the screen, add a printer to a Mac and configure a login hook through a Profile Manager-based policy. Many of the MDM providers have begun adding functionality to their tools to allow for Mac management as well as iOS and I would expect that to become the standard in years to come. iOS is a single-user device and OS X is a multi-user device, which completes that paradigm, but Apple has made it no secret that policy-based management for Mac OS X is moving to the realm MDM (even if that is enforced through a traditional lens of directory services based policy-based management).
One of the unique aspects of the iOS platform is that it doesn’t have a file system that is exposed to users. There’s no /Volumes, no C: drive and no home folders. The devices don’t log into a server, because there’s no way to interpret a server connection. The file system that is exposed to iOS devices is through the lens of each application. Sandbox is a technology that limits each application’s access in terms of memory, hard drive, etc. Each application can only communicate with resources outside of itself if there is an API to do so, APIs mostly reserved for Apple (e.g. photos, contacts, etc). Therefore, when you discuss content management from the perspective of building a large iOS solution, you’re talking about apps.
The apps used for content management come in a few flavors. There are those that allow you to edit content and then there are those that allow you to read content. One way to look at this is through Safari. Sharepoint, WebDAV and various document management portals allow users to access data through the Safari browser on an iOS device. Safari will let you view various file types. But to edit the data, you would need to send it to an app, or copy it to the clipboard and access it in an app. Pages is an example of an app that can browse a file tree via WebDAV and edit content. However, planning how each type of file is accessed and what type of editing can be done on each file type or what type of resources need to be accessible can be difficult (e.g. there are a number of transitions in Keynote presentations that do not work in iOS).
Then there’s iTunes. iTunes allows you to backup and restore devices, update devices, etc. iTunes allows you to drop content into each application. If you look into the ~/Library/Mobile Documents, you can drop content, edit default documents and other tasks that can be done through a command line, then perform a cradled sync to an app. If networking is built into an app then you don’t have to plug a device into a computer. If an app can leverage iCloud, SMB or AFP then you can access data over the air. If you are trying to replace computers with iOS devices (a la post-PC) then you would need to plan each business task that needs to be performed and make sure not only that there is an app for that (or an app you build for that) but also make sure that you can round trip data from a shared repository and back to the network storage that the data resides on.
You can also access many of the benefits of MDM without having an OTA element. This can be done with iPhone Configuration Utility. iPhone Configuration Utility can configure the same policies available through Profile Manager but relies on either a cradled or email/web server/manual way of getting policies onto devices and updating. MDM automates this, but iPhone Configuration Utility is free and can be used as well. Additionally, profiles can be exported from Profile Manager and installed in the email/web server/manual way that iPhone Configuration Utility profiles are installed.
This is all probably starting to seem terribly complicated. Let’s simplify it:
Basically, there’s a few holes here. First, AppleIDs cannot be centrally managed. Second, you need to use gift cards or the Volume Purchasing Program (VPP) to distribute apps, and Third, even when you push an app to an AppleID, the app follows the AppleID to their next organization (which causes many organizations to treat apps like consumables). Fourth, synchronizing content is done primarily through iTunes, which only syncs a device at a time, making preparation of large numbers of systems terribly complicated.
Enter Apple Configurator, a free tool on the Mac App Store. This tool basically fixes all of the problems that we reference, but does so over USB. This means that Apple Configurator is not necessarily a replacement for MDM. In fact, you can deploy Trust and Entrollment profiles for MDM and automate the MDM enrollment for a device through Configurator. Instead, Apple Configurator is a tool that can either Prepare or Supervise an iOS deployment and do so in a manner that is easy enough that you don’t need a firm background in IT to manage devices on a day-to-day basis.
Here is what Apple Configurator can do:
Apple Configurator has some caveats:
I see a number of uses for Apple Configurator. Some of these use cases include:
These can enhance practically every environment I’ve worked with. But unless it’s a small environment (e.g. the labs), Apple Configurator isn’t a replacement for the tools already in use in most cases. Instead, it just makes things better. Overall, Apple Configurator is a welcome addition to the bat belt that we all have for iOS management and deployment. Now that we’ve looked at the when/where of using it, let’s look at the how.
There are two ways to use Apple Configurator. The first is to Prepare Devices. You would use this mode when you’re going to perform the initial setup and configuration of devices but not when the devices won’t be checking back into the computer running Apple Configurator routinely. Preparation settings do not persist. And while applications can be pushed through Preparation, updates for those applications will be tied to the AppleID that purchased the app.
The second is Supervise. Supervising devices is an option when preparing and allows you to have persistent changes to devices, to layer new settings the next time devices are plugged in, to add applications and the most intriguing aspect of iOS management here is reallocating VPP codes to new devices when a user or device is retired. Supervising devices also allows for assigning a given user to a device and thus pushing data into an application.
Setting Up Apple Configurator
Apple Configurator is installed through the Mac App Store. When installed, you are presented with three options. The first (going from left to right) is to Prepare Devices.
Before we get started, we’re going to add our AppleID. The computer running Apple Configurator needs to be able to connect to the App Store and it needs to have an AppleID associated with it if you’re going to use VPP codes. So let’s set that up before moving on. To do so, from Apple Configurator, click on the Apple Configurator menu and click on Preferences… From the Preferences menu, click on Set for the Apple ID and provide an AppleID (not the VPP Program Facilitator).
Then, when prompted, provide the credentials for your AppleID. If you have any problems with this, try Authorizing the computer in iTunes, if you can’t do one it stands to reason you can’t do the other and it’s either an invalid AppleID or that the computer cannot communicate with Apple’s servers (ports, DNS, Internet connectivity, etc might be the issue).
Also, let’s configure the Lock Screen settings, which is what’s displayed to users when you’re supervising devices. If you have user pictures in Open Directory, this will show each user’s photo at the lock screen (we will discuss device supervision later).
Using Apple Configurator to Prepare Devices
In this example, we’re going to prepare some devices for deployment. Before we do anything, we’re going to do a backup of the iOS device to use for testing. To do so, simply click Prepare Devices to bring up the main Apple Configurator screen and then click in the Restore field.
At the Restore menu, click Back Up…
Then choose the device to backup and click on Create Backup… to bring up the screen to select where to save your backup to (by default it should be your Documents but you can save them anywhere, like /iOSBackups). Click Save to make the first backup.
Notice how fast that went (assuming you didn’t load it up with 10 Gigs of crap)? The reason is that we’re not backing up iOS, just the data. This will become a little more obvious the first time we go to restore a device. In the meantime, if you look at your target directory, you’ll see a file with the name you provided followed by .iosdevicebackup. If you aren’t supervising you would need to delete these from the filesystem to remove them from the menu of available backups. If you are supervising then you’ll have a menu to manage the backups. You can also use the Other option in the selection menu to browse to another location and select another backup (e.g. you’re pulling them from other machines, etc.
Now that we have a backup, let’s do some stuff to the device. Let’s join the wireless network, change the wallpaper, create some contacts, make some notes and in general do some of those things that you might do on a base image of a computer, aside from of course configuring local admin (it’s not a multi-user device), installing anti-virus (to date, AV companies for iOS are snake oil salesmen) and other things you might not do. But as with imaging, if you can do something in Profile Manager or Apple Configurator, let’s reserve doing it there. In fact, I would probably try to set everything in Profile Manager or your MDM provider that you can (if you have one) and use Apple Configurator for as little as possible. That goes with imaging as well, do as much in directory services/managed preferences/profiles as you can and keep the image as simple as possible…
Anyway, once you have the device as you want it, make another backup. This is akin to baking an image with DeployStudio or System Image Utility. We can’t asr them out yet, but we’re in a much better place than we were.
Once you have a good backup, let’s leverage Apple Configurator to tell the device erase, update to the latest version of iOS, restore our image, join the SSID of our enrollment network (let’s consider this similar to a supplicant network in 802.1x). Then, let’s add a profile that will throw a Web Clip to our MDM solution and even add a Trust Profile to cut down on the number of taps to enroll (and the confusion of tap here, tap there, etc). From the Prepare screen in Apple Configurator, click on Settings and type the naming convention for your devices (in this case we’re going to call them krypted 1 and up) in the Name field. Then check the box for Number sequentially starting at 1 so it’s going to name them from 1 to 1,000,000 (which is how many iPads my krypted company is going to end up writing off at the testing rate I’m on now). Leave Supervision set to OFF (we’ll look at that later) and set the iOS field to Latest. Then, check the box for Erase all contents and settings and choose your image from the Restore menu.
Now for something that users of iPhone Configuration Utility, Profile Manager and Casper MDM will find familiar, click on the plus sign in the Profiles field and select Create New Profile. Here, we see what is the standard policy sheet (apologies to HIG if that’s not what those are officially called but I’ve not been able to find the right term) and give it a name in the Name field. This is how it will appear in the Profiles section of Apple Configurator. Because you can deploy multiple profiles, I’m just going to configure the SSID and Web Clip and call it MDM Enrollment. Optionally, give it some notes, organization name, etc.
Click on Wi-Fi and then click on the Configure button. Here, enter the SSID of the deployment network (MDMEnroll in this example). We’ll use the Hidden Network field to indicate the SSID is suppressed and we’ll use the network type of WEP and throw the password into the Password field as well. Now, before we move on, notice that there’s a plus and minus sign in the top right of the screen? You can deploy multiple of each, so if you have 10 wireless networks, 4 Email accounts, 9 VPN connections, 29 SSL Certs etc, you could deploy them all easily with multiple entries of each.
Scroll down in the sidebar a little and then click on Web Clips. Click on the Configure button. The Label is how the web clip’s name will appear on the device. We’re going to enter Enroll Here. In the URL field, provide the URL for your MDM server (e.g. When using a Profile Manager server called mdm.krypted.com the URL would be https://mdm.krypted.com/MyDevices). Not to get off topic, but did anyone else notice that Profile Manager in 10.7.3 now requires SSL certs? Anyway, you’ll also choose whether the web clip should be Removable (I think it should if it’s to enroll) and optionally choose an Icon. We’ll skip that (if we were using a 3rd party tool, I’d throw their logo in here; otherwise I usually like to use the company logo. I also like enrollment links to be Full Screen.
Go ahead and click Save and you’ll see MDM Enrollment listed in the Settings. If you notice, you can also click on the profile and then click on the export menu to export the profile or under the plus sign (“+”) you can Import Profile…, which is how we’ll bring in our Trust Profile from Profile Manager. From Profile Manager we already downloaded the Trust Profile. Now we’re going to click on Import Profile… and browse to it on the desktop, clicking on Trust profile.mobileconfig (or whatever name yours may have). Click Open.
We could go a step further and actually enroll the device by exporting the enrollment profile as well, but again, I want each user to provide their username and password so I as an administrator don’t have to go through and attach each device to a user in this scenario. I’ve been looking at importing devices and associating them with users via postgres, but that’s going to be another 3am article, on another night…
Next, check the box for each profile and click on Apps. This is where things start getting kinda’ cool. For this you’re going to need some app ipas. Each app in iTunes is stored as an .ipa file. We’re going to look at two different kinds of apps. The first is a free one and the second is a paid for app, both we’ll pull from iTunes. To do so, open iTunes and click on an app (iBooks in our example) and click on Show in Finder.
Note: Not all app .ipas are called the same thing as the filename. If you Show in Finder from the contextual menu of an app in iTunes it will automatically highlight the correct app in the Finder when it opens a Finder screen.
From the Finder you can either copy the app to the machine running Apple Configurator or if you’re using iTunes on that machine, you can go ahead and drag it to the Apple Configurator apps list. We’re also going to add an App that we used a purchase code from the VPP store to buy. You’ll get an error when you drag the paid app in (or browse to it if you so choose) that indicates the app is paid and in order to deploy it you’ll need to use VPP codes. Once added, you’ll notice it has an error indicator and the number 0 beside it.
Click on the numerical indicator beside the app name and you’ll be able to import redemption codes. These are emailed to you when you buy apps through the Volume Purchasing Program. BTW, no drag and drop in this screen, use the Important Redemption Codes button to browse to the XLS files.
Using Apple Configurator to Supervise Devices
Now, supervising devices may seem more complicated, but it isn’t. Back at the Prepare screen, we set Supervision to OFF. Change the iOS field to No Change. Now, let’s turn it ON. When you do so, the iOS field automatically switches to Latest. This means that supervision is going to require updates (which is fine in my book as updates have yet to break a single app for me). Get all the same settings the same as they were previously.
Once you enable Supervision, click on Prepare in Apple Configurator and connect a device again. The device will then be imaged as with the same settings that you’ve given it from before. However, once it’s done, you’ll be able to click on the Supervise tab and see devices (Note: You supervise devices rather than users).
The subsequent Starts and Stops will now allow you to enable and disable profiles and apps on the fly, as well as restore backups, update devices and as you can see in this screen, reclaim those valuable VPP codes!
Do a Get Info on a device and you’ll also see a bevy of information about that device.
You can also click on Assign, once you’ve enabled Supervision. Assigning devices requires directory services. When you click on Assign, click on the plus sign (“+”) to add the first user. Type the first few letters of the users name and they should appear in the list. Click on them and they’ll be added. You can then use the right panel to assign content to the apps that you assign to that user’s devices.
Once added, the user will by default have no device. To assign a device to a user, use the Check Out box at the bottom of the screen and then match the users with the devices you want them to have.
The final piece of this application is to assign content to users. As I mentioned earlier in this article, the file system of an iOS device is through the lens of the applications that the device has installed. Therefore, we’ll be associating files to applications. DRMd content is not distributed through Apple Configurator. So iBooks, etc, aren’t applicable. The various third party applications can open and therefore host file types that they support, as with iTunes. From the Assign pane of Apple Configurator, click on a user and then click on the plus sign (“+”) to add documents. At the Choose A Target Application screen, choose the application you’ll be loading content into.
When you click Choose, you’ll then be able to select files to use with that application.
Then just dock the iOS device, sync and viola you’ve got content distribution over USB all handled. You can also add groups of devices and groups of users and distribute content to groups of users rather than to one at a time.
Apple Configurator is really a great tool when used in the right scenarios. In learning how it works and interacts I actually learned a lot about both iOS and Mac OS X that I didn’t know before. I hope I did the tool justice with how easy it is to use. This is a fairly long article and it’s probably more complicated than it needs to be in parts, but that’s more my method of trying to figure out what it’s doing than the tool being complicated. It’s not hard to figure out at all. I am sure I could teach any non-technical iOS admin to use it in less than an hour.
My wish list includes logs and OTA. You can’t use iPhone Configuration Utility while you’re using Apple Configurator and therefore, you can’s see up-to-the second logs about things like key bags to figure out why this isn’t working or that. This makes it kinda’ difficult to figure out why a profile doesn’t get installed with an image if you’re not using an AppleID with the tool or other weird little things like that. I’d love to see a little more logging. Obviously, if you could run this thing Over the Air then it would be nerd nirvana. I guess the OTA isn’t as much as wish list for this tool, but features that could be imported into Profile Manager and other tools.
One of the more important aspects is the impact on AppleID use and app ownership. I started this off by saying “My traditional interpretation of Apple’s vision on how iOS devices are used is that everyone has an AppleID.” Well, when using this tool an AppleID is no longer necessary for app deployment.
Overall, we have a new, powerful tool in our arsenal that makes up the iOS administration ecosystem. I hope that I’ve managed to dispel a few rumors with this article and look at some great uses for where this tool should and should not be used. I also hope that no matter what, if you manage iOS devices, that you’ll take a look at it. I expect you’ll find it useful in some part of your management toolkit!
