Childproof Your Mac

When I put a computer in my daughters room, I soon realized I could no longer watch over her shoulder as she worked away at school games, Minecraft and of course Civilization (after all, that was my first game). So much as I wrote an article a long time ago about child-proofing an iPad, now I’m writing about child-proofing a Mac.

For me, I find that child-proofing is a bit like taking my kid to McDonald’s. I said never ever ever ever would I do this and then… Well, peer pressure, ya’ll… So if I have to do it, I figure someone else might. So here’s a quick and dirty guide to doing so. The gist of this guide is to continue using the same admin account that was created when you setup the computer initially. But to also create another account for the child, one that has some restrictions to keep them in a customized user experience. This might be to keep them out of things they try to do on purpose, keep them from accidentally finding some things they shouldn’t or maybe just to customize the user experience to make the computer easier to use (after all, if they can’t remove Minecraft from the Dock, they can’t come crying when they can’t find it.

Create a Managed Account

Most of the work that needs to be done, can be done within the System Preferences. This is available under the Apple menu as System Preferences…

Once open, click on the Users & Groups System Preference.

Screen Shot 2014-12-26 at 5.09.41 PM

At the Users & Groups System Preference pane, click on the plus sign (+).

Childproof_Managed_Account

 

At the new account screen, choose “Managed with Parental Controls” in the New Account field. Then provide the child’s name in the Full Name field and an Account Name will be automatically created (note that I shortened the name in this example to make it easier for the child to log in).

Assuming your child doesn’t have their own iCloud account, set the password to “Use separate password” and then type it in. Once you’re happy with these settings, create the new account, which can be managed with Parental Controls by clicking on the Create User button.

Childproof_User

Restrict Applications and The Dock

Once the account is created, click on the “Enable parental controls” checkbox and then on the Open Parental Controls… button.

Screen Shot 2014-12-26 at 5.01.32 PM

At the Parental Controls System Preference pane, you’ll have a few options.

  • Check the Use Simple Finder box if you’d like the user to have a limited user experience (no command keys, only certain windows open, etc). I would usually only recommend doing this if you have very small children (like maybe pre-school age). I usually like them to be able to do as much as possible to foster the whole hacker mentality nice and young!
  • Check the box for Limit Applications if you’d only like certain apps to open. This is right up front on the main screen because it’s kinda’ important. Use the Allowed Apps section to select which apps can and can’t be opened (if there’s a checkbox beside the app name it can be opened by the user).
  • Use the Allow App Store Apps drop-down list to to set an age ranking minimum. These are available in 4+, 9+, 12+, 17+ and All (which basically disables restrictions).
  • Check the box for “Prevent the Dock from being modified” if you would like to restrict the new account from being able to edit the Dock. I usually wait for this, as I like to customize the Dock by putting the apps I want the child to open into the Dock. To do so, skip now, log in as the new user, log out and then customize the Dock. Once you’re done, log out, log in as an administrative user and then check the box.

Web Restrictions

Next, click on the Web tab. Here, you’ll effectively have 3 options: don’t restrict any content, let Apple try and block inappropriate content and build a whitelist of allowed content (with all other content blocked). Now, it’s worth mentioning that there can be an annoying element here, which is that if a site needs to be opened up for access, a child might come bugging you. But I like that, so I’m configuring this.

Screen Shot 2014-12-26 at 5.01.40 PM

Options include:

  • Allow unrestricted access to websites: Don’t block any content. Allow unfettered access to all websites ever.
  • Try to limit access to adult websites automatically: Click on the Customize button to add white and blacklisted sites, or sites that were accidentally restricted or allowed that maybe shouldn’t of. Or, if you want to restrict access to a specific web-based game that has become problematic.Screen Shot 2014-12-26 at 5.46.23 PM
  • Allow access to only these websites: This option allows access to only the websites you allow access to. A word of warning here, a lot of sites pull content from other sites, which can be kinda’ annoying…

Note: It’s worth mentioning that I discovered a few websites I’d of never tried to use in the allow list, so worth checking them out to see if your child will dig on some of these sites!

Once you’re satisfied with the options you’ve configured, click on the People tab.

Configure Who Your Child Can Communicate With

At the People screen, you can configure who the person using the Managed Account can communicate with. Here, restrict access to Game Center, restrict who the account can send and receive mail with and of course, who the account can use the Messages app with.

Screen Shot 2014-12-26 at 5.02.09 PM

The above options include the following:

  • Allow joining Game Center multiplayer games: Uncheck this box to restrict the user from playing any multiplayer games that use Game Center to connect people. If the user is using a game that doesn’t integrate with Game Center then they would still be able to use that game to enter into a multi-player game.
  • Allow adding Game Center friends: Uncheck this box to keep the user with the Managed Account from adding any new friends in Game Center.
  • Limit Mail to allowed contacts: Only allow people in the Allowed Contacts section to exchange emails with the user of the account.
  • Send requests to: Define an email address that can receive a contact request and approve it. I use this so that when my daughter needs something she can let me know.
  • Limit Messages to allowed contacts: Only allow people in the Allowed Contacts section to message with the user of the account.
  • Allowed Contacts: Use the plus sign at the bottom of this section of the screen to add new contacts and the minus button to remove contacts.

Note: Apple rarely uses the word restrict. Instead, they prefer to allow things to happen by default and then let you disallow these features. Basically the same thing, but keep this in mind when you’re configuring accounts as sometimes you can accidentally click the wrong thing if you’re not accustomed to such double-negativery. 

Once you have configured who the user of this account can communicate with, click on the Time Limits tab.

Configure Time Limits

Time limits are used to restrict what times the user can use the computer as well as how long per day that the user can actually use the computer. The options available include:

  • Limit weekday use to: Define a maximum number of hours that the managed user can use the computer on a given workday between Monday through Friday. This can be anywhere from half an hour to 8 hours of time.
  • Limit weekend use to: Define a maximum number of hours that the managed user can use the computer on a given Saturday or Sunday. This can be anywhere from half an hour to 8 hours of time.
  • School nights: Define the time frames where the computer cannot be used by the Managed User on Sunday through Thursday evenings. For example, the below screen shows that on weeknights, the Emerald Edge user can’t use the computer from 8PM to 6AM.
  • Weekend: Define the time frames where the computer cannot be used by the Managed User on Friday and Saturday nights. For example, the below screen shows that on weeknights, the Emerald Edge user can’t use the computer from 8PM to 6AM.

Screen Shot 2014-12-26 at 5.02.40 PM

Time limits are the only things that matter for some who like to physically sit with a child while they use a computer, as you might just want to keep the child from waking up in the middle of the night and accidentally seeing something that scares them. But for many, time limits won’t be enough, as kids might spend hours gaming or doing homework unmonitored.

More Stuffs

Next, click the Other tab. Here, you’ve got the miscellaneous restrictions that really don’t fit anywhere else in Parental Controls. The options available include the following:

  • Disable built-in camera: Turn off the built-in camera for the user. Note that third party cameras wills till work for the user.
  • Disable Dictation: Turn off Dictation/Speakable Items for the user. Note that apps like Dragon Naturally Speaking can still be used.
  • Hide profanity in Dictionary: Use this option to disable any articles in the Dictionary app that have profanity in them.
  • Limit printer administration: Don’t allow the user to manage printers. Note that if you do this, you’ll want to install any Bonjour printers first.
  • Disable changing the password: Don’t allow the user to change the password.
  • Limit CD and DVD burning: Disable any optical media writing for the Managed Account.

Screen Shot 2014-12-26 at 5.03.09 PM

Note: I know I said earlier that Apple rarely says restrict or disable. They will get around to fixing this screen eventually… ;)

View Logs

Once you have configured parental Controls, click on that Logs button in the lower right corner of the screen. Here, you’ll see the following:

  • Show activity for: Indicate the period of time to show logs for.
  • Websites Visited: A list of the websites accessed by the user of the managed account. Note that no third party web browsers are shown unless they use Apple’s webkit (which is basically not really any).
  • Websites Blocked: A list of any websites that were blocked while attempting to access them.
  • Applications: A list of the applications used by the user of the managed account.
  • Messages: Transcripts of conversations sent and received using the Messages app. Note that any third party chatting apps aren’t logged here.
  • Clear Log: Deletes the log. Use this after you’ve checked the behavior and wish to have the next time you check only show you what’s changed.

Screen Shot 2014-12-26 at 5.02.49 PM

And that’s what you can do with Parental Controls. But there’s more, which we’ll look at shortly. When you click out of a field, the settings are changed in a System Preference, so you should be able to just close the window and have your settings persist.

Conclusion

We’ve gone through creating a new account, restricting access to what that account can do and how and when to use these options. But there’s much, much more than we can cover in this article. There are tons of other restrictions that don’t fit into these basic options, accessed either through what are known as managed preferences or via profiles, which can easily be created by tools like Apple Configurator, Profile Manager and 3rd party mobile device management tools such as Bushel.

Screen Shot 2014-12-26 at 6.13.22 PM

Ultimately, I can pretty much break out of about any managed environment you put me in. And in the age of YouTube, chances are that your child has many the same materials I’ve either presented, written or that others have written. So please don’t consider these options as much more than just a general guideline unless you’re using a Device Enrollment Program-enabled device.

Anyway, good luck, and you’re a good parent for caring.

Be A Good Patriotic American By Renting Sony’s The Interview

Recently I’ve read a lot of things about the attacks against Sony. I’ve read that they’re nothing more than extortion attempts by hackers that probably live in their parents basements (based on the fact that the initial demands didn’t mention North Korea at all). I’ve read they were orchestrated by China by people who felt North Korea was being picked on and couldn’t stand up for themselves. I’ve read highly unconvincing reports from the FBI that they were orchestrated by North Korea. No one really knows. I can send traffic to servers from anywhere in the world. Anyone can anonymize their web traffic as easily as using a ToR plug-in with Firefox. I’ve also spoken to friends at Sony that told me that they’re concerned about the future viability of Sony due to the business impacts of these attacks. I’ve also spoken with people at other studios freaking out about not wanting to “be the next Sony.”

But in all of it, there’s something kicking in the back of my head. You see, if someone tried to blackmail me, I’d go to the press (or government) and allow the public to judge me for whatever it is, not cave to demands that are only likely to recur. Not giving into extortion demands is the right thing to do. If someone threatened the safety of people to go to a movie, I’d pull it as well, so that’s the right thing to do as well. There have been enough shootings in theaters and while financially potentially devastating it’s not worth the loss of a single human life to show The Interview in theaters. Of course, now that the attackers have backed off their stance, The Interview will be shown in hundreds of theaters. And it will likely be viewed online by millions of people over the next few days. And if this was carried out by North Korea, they couldn’t visit all of our homes to pull it (although the awful remake of Red Dawn by MGM might indicate differently).

I believe that the good, American thing to do is show our support to Sony for all the brain candy they’ve given us in the past. More than that, our support for doing what’s right. And what’s more capitalistic of us than spending $6 on a movie (other than spending more)? What’s better for Sony than to make a little money? In America, we tend to root for underdogs. We love Rocky (which btw cost less than a million to make and brought in a breathtaking $225M – 1:225 ROI there). We wanted Rudy to score a touchdown for the Irish (TriStar – part of Sony). We practiced our kicks like the Karate Kid (Columbia Pictures – part of Sony). We watched Jerry Maguire (TriStar – part of Sony again) even though we couldn’t stand Tom Cruise and rooted for the guy who risked it all to do the right thing (Money, baby). We threw up in our mouth a little when we watched Dodgeball (Fox but a fun movie anyways). We adore Gandhi (Columbia – again part of Sony) because it won an Oscar and taught us the story of one of the greatest men of all time. We loved Charlie Sheen when he was Winning in Major League (Mirage). And we loved Kick-Ass (Lions Gate), one of the unlikeliest heros of all.

Sony made Bond great again. Sony brought us Spiderman to the big screen. Sony told us about The Social Network (and were still allowed to have Facebook accounts. Sony gave us Eat Pray Love. Sony killed zombies awesome sauce in Zombieland. Sony gave us Superbad. Sony taught us a history lesson with The King’s Speech. Sony brought The Da Vinci Code to the big screen. Sony made a great movie in the Lords of Dogtown. Sony brought us Hell Boy, Adaptation (as a writer, a movie I love), Ali, Black Hawk Down and countless other movies. Some great, some not. That’s the game.

Now, we have a chance to do a very small part by helping Sony escape financial ruin. And yes, they make more movies that suck than are awesome. Because that’s what all studios do. And yes, the film industry seems like a bunch of rich people being silly sometimes. But there are real people that work there. Normal people. With boys and girls and installations at burning man. Some of the best people I know. And they do great work. And sometimes the studio makes brilliant movies. And whether this was spearheaded (yes, bad pun on spear phishing) by a dictator with a bad fade, the remaining communist hardliners in China, another studio or something else, it’s up to the market to dictate the outcome. That’s capitalism. ‘Merica

PS – It’s hilarious.

Minnebar Presentations Available On YouTube

I was supposed to give a presentation at MinneBar a few weeks ago, but I ended up having to be out of town. I was pretty bummed as I really wanted to see a few of the presentations. But, lucky me, MinneBar has actually started posting presentations to YouTube. Woohoo, they’re available at http://www.youtube.com/user/MinneStarMedia.

The one I think I was most interested in seeing is available right here, and I can embed it into my own site and watch it from here.

I will try and make the next one to do the presentation I’d planned on giving. This is a community I am very supportive of and love contributing to (although the next time someone uses “serial entrepreneur” as their job title I might not be able to suppress the eye roll + flutter combination – sry).

A Little Bit Of What I Do

People often ask me what I do for a living and my answer is usually that I get paid to play with computers and manage people who play with computers. But if I were to drill down, I really do a lot of different things (as you can probably tell if you’ve seen a lot of my posts). But one of my favorite things to do is unwrap tons of shiny new computers and put them into the hands of students. The potential, the excitement, the smiles make much of the other stuff worthwhile. You actually get to feel like you made the world slightly better. We usually refer to this as imaging. The process usually starts by installing a master or capturing a thin image and then automating all of the software that goes into making the system useable by end users. Then, test, test, test. After a day or 10 of this process we can then get those shiny new computers on desks and start up our automations. This last part can be pretty fun. And Ben Pirozzolo captured that fun in this little video. I hope you enjoy it as much as I do and total hat tip to Ben for capturing a sliver of my life in such a fun way!

Apple Finally Finds YouTube

Apple has been interfacing with YouTube for some time. They have provided YouTube integration into a number of their consumer applications and clearly understand how to aggregate content from YouTube and interface with the YouTube API. Apple also has some of the best marketing of the past 10 or more years. But until now, Apple has been quiet on the YouTube front. Now, with the introduction of the iPad, Apple has quietly started a YouTube presence. I can’t help but wonder what Apple has in store for the field of interactive marketing!

Gadgets & Videos

I added new pages for Google Gadgets and YouTube Videos to the navbar at the top of the screen. The Gadgets are the common gadgets I use and the Videos is a rendition of the krypted318 channel. Hope you find these useful. Look for additional applications to be added to the fat client stuff shortly.
