Manage Apps On The Apple Watch

The Apple Watch is just another wearable with a limited feature set. In much the same way that the iPhone is just another phone. But they’re not. They have apps. And the apps are what make these devices so powerful. Installing apps on an Apple Watch is pretty straight forward. But before we do, it’s worth mentioning that there are two types. the first is a glance. This is just another view for an app that is on your iPhone that the Apple Watch talks to. The second is an actual app. These have more functionality and more options. There are also built-in apps that can be shown or hidden.

Apps are managed from the phone. To install either type of app, simply open the Apple Watch app on your phone. From there, you will see any apps that have either an app or a glance available on a device.

Tap on an entry and you’ll see whatever is available for that app. New apps aren’t displayed on your Apple Watch. Use the slider to control whether it is displayed or not.

Some apps have more options. If so, tap on the app and enable those options if needed. When you enable these apps, you’ll see the icon start loading on the watch, in much the same way that an icon starts to load on a phone when you purchase the app from the App Store.

Also, some apps, when you download an update to the app, will even prompt you to install a glance for the app on your phone.

The apps show up on right side of the default apps on the watch.

Here’s the Nike app. This app only works properly when you open the app on the phone. It sits at a loading screen and only opens when the app on the phone opens. When it shows up, you can then do whatever the app is built to do. In this case, start and stop runs.

That’s it. Straight forward. Just be patient. Takes awhile for Apple Watches to communicate with phones and to move data back and forth between them.

Apple Watch Vs. Pebble DeathMatch (Comparison)

When I started to write this, I had this idea that I’d write an article that looked at the features and the usability of the Pebble and those of the Apple Watch. Both have the ability to load custom apps, both have app stores, both do many of the same other tasks, etc.

watch-dmPebble_Technology_Pebble_669108_i0

The problem with that premise for this article is that they simply aren’t even remotely comparable. Let’s look at why:

  • Apps: The Apple Watch can support apps and glances from apps. You can load as many as the thing can take, you can get different types of apps and there are already hundreds (if not thousands – I don’t have the patience to count) of apps that have support for the Apple Watch. The Pebble on the other hand is limited to 8 concurrent apps and I have never actually found more than 5 that I wanted to use that didn’t involve a watch face.
  • Watch faces: I don’t change watch faces really. Most of the apps on a Pebble are all about custom watch faces. Pick your favorite school, your favorite Disney character, etc. The watch faces available for the Apple Watch are great and all, but the default face, with instant access to the calendar, your exercise stats, the weather, and of course the time, are is really what the device is about and the best usability option, something Apple has always excelled at. It would be great if the other time zone option on the Apple Watch had some really cool stuff you could swap it out with. If you force tap on the screen, you can certainly select other things, but all the cool stuff is placed in other areas of the default watch face.
  • The screen: The screen on the Apple Watch is just a beautiful screen, with full color, lots of pixels, etc. The screen on the Pebble more closely resembles options from an Atari 2600. So, think Wii vs 2600 (aka e-paper)…
  • The app that manages the wearable: The Apple Watch app has in app controls for what’s available on phones, can configure which apps/glances are shown, unpair/re-pair, configure notifications, manage Do Not Disturb, put the device into Do Not Disturb mode, configure passcodes, manage sounds and vibrations, configure brightness and size. It’s pretty robust. The app for the Pebble does much less, but is on par given the features available on the device in general.
  • Light: The type of light emitted by the Pebble actually makes it a little easier to see in sunlight to me. But if you have sunglasses on then forget about it. Which I usually do when there’s a lot of sunlight. But this is a showstopper for some. Like those who (legitimately) still look for raised keyboards on phones…
  • Battery life: The Pebble kicks the crap out the Apple Watch when it comes to battery life. I’ve not charged my Pebble once in a week and it was happily camping straight into the next week. My Apple Watch must be charged daily.
  • Older iPhones: The Pebble can work on any iOS 6 compatible device (and up). The Apple Watch needs an iOS 8 device. So if you have an older phone, you’ll likely want a Pebble. Or take this as the opportunity to stop listening to 90s era Brittany Spears and upgrade your phone when you buy a watch.
  • App security: There are apps that can muck up a Pebble. This ranges from screen distortion to apps crashing. I tend to think that if an app can cause a device to crash then it could be intentionally designed to do more worser (yes, that was on purpose) things to the device as well. I could be wrong and haven’t spent any real time doing security research on the device, but it seems like a bad thing. Meanwhile, apps that go to an Apple Watch go through the App Store and so have at least some semblance of review.
  • Music Control: I like the Pebble more in this respect. It instantly sends commands to music on your phone. The Apple Watch always seems to be just a little bit delayed (not bad, but I can notice the delay). Having said that, the Apple Watch also has a Remote app, so you can also control music streaming out of computers onto Apple TVs.
  • Instant Messaging: The Pebble can show you messages. The Apple Watch can as well, but goes a step or 10 further and actually allows you to send voice messages, text messages, animated Emoji and even your heartbeat (which people keep creepily sending me – except that one guy who has none – but we all knew he was a lich so whatever on that).
  • Fitness: The fitness options on the Pebble are mostly from apps. The apps are a bit limited, but you can do a few pretty cool things. There are more built-in options on the Apple Watch; however, the 3rd party apps for Fitness tracking are pretty considerable and growing daily.
  • Pay for all the stuffs: Apple Pay isn’t the most widely accepted form of payment around, but it is gaining in popularity and pretty cool. Not sure if NFC is really going to be changing the world, but it might, and a wearable that isn’t specifically a fitness tracker is likely going to need it over the coming year.
  • Price: The Pebble can be $89. The Apple Watch starts at $350 and goes up to thousands (10 of ’em actually).

Overall, the Pebble is inexpensive. At 4 times the cost is the Apple Watch, which has less battery power but way more features. So it’s not Apples to Apples (no pun intended) to compare these. If you’re interested in a really inexpensive wearable and not worried about all the crazy features that come on them, check out the Pebble. But, the Apple Watch, as with many an Apple product, is very much worth the price tag. Unless you’re getting a gold one…

Need A Password? There’s An App For That!

Remember this comic:

Regrettably, password policies don’t allow for a few random words at most organization, so a special character, a capital letter and a number are basically required in most passwords these days. However, if you need a quick and dirty generator that includes a phrase and those additional characters, consider MyPhrase from Björn Albers. It’s simple to use, fast and easy. Good luck out there!

Configuring Alerts in Mavericks Server

Mavericks Server comes with a few new alerting options previously unavailable in versions of OS X. The alerts are sent to administrators via servermgrd and configured in the Server app (Server 3). To configure alerts in Mavericks Server, open the Server app and then click on Alerts in the Server app sidebar. Next, click on the Delivery tab.

Screen Shot 2013-10-04 at 8.30.47 PM

At the Delivery screen, click on the Edit button for Email Addresses and enter every email address that should receive alerts sent from the server. Then click on the Edit button for Push Notifications. Here, check the box for each administrator of the server. The email address on file for the user then receives push notifications of events from the server.

Screen Shot 2013-10-04 at 8.29.40 PM

Click on OK when you’ve configured all of the appropriate administrators for alerting. Click on the Edit… button for Push and if Push notifications are not already enabled you will run through the Push Notification configuration wizard.

Screen Shot 2013-10-04 at 8.40.33 PM

Then, check the boxes for Email and Push for each of the alerts you want to receive (you don’t have to check both for each entry). Alerts have changed in OS X Server, they are no longer based on the SMART status of drives or capacity; instead Delivery is now based on service settings.

Finally, as with previous versions of OS X Server, Mavericks Server has snmp built in. The configuration file for which is located in the /private/etc/snmp/snmpd.conf and the built-in LaunchDaemon is org.net-snmp.snmpd, where the actual binary being called is /usr/sbin/snmpd (and by default it’s called with a -f option). Once started, the default community name should be COMMUNITY (easily changed in the conf file) and to test, use the following command from a client (the client is 192.168.210.99 in the following example):

snmpwalk -On -v 1 -c COMMUNITY 192.168.210.99

Programmatically Disable Notification Center in Mountain Lion (aka My Battery Life Sucks)

There are a few ways I like to extend my battery life on my MacBook Air. These days, it’s increasingly important to conserve battery life as the transition to Mountain Lion (Mac OS X 10.8) has caused my battery life to spiral into so much of a vortex that I am concerned that my laptop must be shooting raw electricity out of the bottom (which would certainly explain why my hair has a tendency to be perpendicular with the ground when I exit a plane). Ever since moving to Mountain Lion (yes, this includes 10.8.2), I’m lucky to get 3 hours of battery life out of the Mac that used to give me at least 5 hours…

There are a number of tricks that I use to extend battery life. Some are obvious, such as dimming the screen, only using an app at a time, killing off menu items, temporarily stop Spotlight Indexing and killing off LaunchDaemons and LaunchAgents that I’m not using. I even used to used an app called CoolBookController to throttle my processor speeds while flying. But that doesn’t work as of Lion (certainly not in Mountain Lion).

One thing that I’ve been able to do that extends my battery life a little more (maybe an extra half hour) is to kill off Notification Center (I wrote about customizing Notification Center earlier here). I know, I know, it shouldn’t matter… But recently, a customer asked me to script disabling Notification Center. Since I’ve been killing it off with a script, this was a pretty straight forward task. It’s easy to disable Notification Center temporarily using the GUI. Simply click on the Notification Center icon in the menu bar and then scroll up to see the “Show Alerts and Banners” button. Click OFF or ON to toggle it off and on. As you can see, Notification Center then starts back up the next day.

To disable Notification Center from the command line, write a KeepAlive key that is false into the /System/Library/LaunchAgents/com.apple.notificationcenterui.plist like so:

sudo defaults write /System/Library/LaunchAgents/com.apple.notificationcenterui KeepAlive -bool false

Then, if you kill NotificationCenter off, it’ll stay off:

killall NotificationCenter

If you want to re-enable Notification Center, you’d just run the same with a true:

sudo defaults write /System/Library/LaunchAgents/com.apple.notificationcenterui KeepAlive -bool true

The easy way to then get it back is to reboot. Now, just for giggles, Notification Center is actually the /System/Library/CoreServices/NotificationCenter.app and in there lies the /System/Library/CoreServices/NotificationCenter.app/Contents/MacOS/NotificationCenter binary. If you open it, you’ll get multiple Notification Center icons in the menu bar. I’m not sure why I decided to try that at some point. But it’s kinda’ fun…

Ultimately, I travel with multiple MacBooks, so rather than toss one of them in a checked bag, or one destined for the overhead, I am temporarily just keeping a second 11 in the bag I keep under the seat in front of me for now…

Determining .app Executables From a Script

I’ve mentioned the codesign tool in previous articles, but today let’s look at a specific use. I recently needed to generate a report of the executable for around 2000 app bundles. Luckily, codesign displays the executable for an app when run with the –display option:

codesign --display /Applications/Utilities/Terminal.app

The output looks as follows:

Executable=/Applications/Utilities/Terminal.app/Contents/MacOS/Terminal

Another tool that I haven’t written much about is productsign (also in /usr/sbin of Mac OS X 10.8). I’ll look at that one next, as a means of signing packages.

Cryptix: Encryption Made Easy

Cryptix is a nice little app available on the App Store that allows you to encrypt and decrypt files using a variety of algorithms. However, while an easy to use encryption tool, it’s actually an even better learning tool for figuring out how various types of encryption techniques actually work.

When you first open Cryptix, you’ll see a list of supported algorithms for encrypting files and passphrases. That part is simple enough, but click on the Tools icon in the toolbar.

Here, you’ll see a number of features along the sidebar, including Checksum, which performs a quick checksum of files dragged on top of the green arrow and tracks hashes, based on the algorithm you choose. Below that can be found more detailed information about interfaces, man page access and a few other things that show the developer was learning how to do a few neat things while writing the tool (such as using DNS from the tool).

Overall, the encryption and decryption aspects of this tool alone are worth the price on the App Store. The checksums are super fast. The other features are interesting as well. I don’t do a lot of app reviews, but this one unexpectedly caught me off guard as something I’d recommend.

MacTech InDepth In New York

I have been added as a speaker at MacTech InDepth in New York. If you haven’t signed up yet, and you work with Mac OS X Server then you should really check out the sessions that have been planned:

  • The Elephant in the Room: The New Lion OS X is out, now what? There are a lot of differences to contend with between Lion and Snow Leopard. Now with the new Mountain Lion update, what changes can we expect to see? We discuss the differences in advanced services, GUI simplicity, and Apache management GUI’s. We help you understand the updates in the new OS and make the transition easier. We go over the new updates of Lion over the Snow Leopard server.
  • Setting solid foundations: To truly grasp the power of Lion, you need to set up solid foundations. We go over minimum requirements for internet DNS, and tackle router tricks. We discuss open directory and what it was used for.
  • Mobile Device Management 101: Apple’s IPCU/Apple Configurator: Mobile Device Management is vital to businesses, large or small. We have an extensive overview of profile manager and how you can use mobile device management on OS X. For those still using Snow Leopard, we go over your options and discuss the possibility of using third parties as a solution.
  • DNS, Ahh, run away, run away: In this session, we tackle DNS and break it down and show how simple it is to work with. We go over how DNS works and cover different components such as internet DNS and internal DNS.
  • Administering a Server with just Server.app: We show you how to use server.app and control administrative programs. For the services, we go over Address Book, iCal, iChat, and Mail.
  • Web Administration of OS X Server : Web Admin on Lion Server versus Snow Leopard is covered, dealing with the differences and how to use each system effectively. On Lion server, we cover using FTP without a GUI.
  • Going old school, using the old tools: After getting used to Snow Leopard we go over the major differences between Snow and Lion and how you can handle the transition. We go over server admin and what is still left in the program and why it has been left.
  • Deployment Part I: Tools & Concepts: In tools and concepts we learn that there aren’t stark differences between Lion server and Snow Leopard. NetBoot, NetRestore and third party tools are covered; we talk about how NetBoot works and what the differences between NetBoot and NetRestore are. Along with this we cover Network configuration requirements and using software update server.
  • Deployment Part II: DeployStudio: DeployStudio is covered in-depth; we cover creation techniques and management techniques.

Overall, this represents a nice, fast way to update your skills to allow for managing Lion Server and to get up to speed with those new to the platform. One thing I like about the session list is that it goes beyond the stock server implementation and looks at DeployStudio, MDM and other important topics not purely server oriented. I hope to see you all there!

Man Pages Made Easy

Ever since upgrading to Lion I’ve been making a few slight changes in workflow. One such change, which I’m still on the fence about, is to switch from reading man pages in a tiled Terminal screen, to reading them in a browser window.

It seems like a small thing, but I spend a lot of time switching between terminal screens or using screen to switch between sessions. Bwana allows you to read a man page from within a browser.

Simply load download the Bwana app into your /Applications directory and wait a few seconds. Then open a browser window and look for a man page. For example:

man:dsconfigad

Now, you may notice that you can’t actually click on the link above and have the link open as it would if you typed the information into the browser manually. You could also use man://dsconfigad to access a man page, but you still cannot refer to those from other sites. You can open those urls using terminal:

open man://dsconfigad

To see an index of all pages, enter the following in Safari:

man:index

To reindex:

man:index_refresh
