OS X Mountain Lion added some new security features to an already fairly secure operating system (not perfect, we know!). One of these features is an alert you get when you use an app that wants to access your Contact information from the Contacts app on your Mac. When you see this, you’re able to allow or deny that app access to your contacts – this is there to help make things a bit more transparent, and hopefully more secure.
Once you’ve given that access, however, that app gets tracked as one that can always access your Contacts info. If you want to change that access, today’s tip will help.
Launch System Preferences, either from the Dock, or the Apple menu, or with an app Launcher like Alfred or Quicksilver. Click on the Security & Privacy panel, and then click on the Privacy button at the top. You’ll see several things to the left, including Contacts, Location Services, Twitter, and Diagnostics & Usage. Click on Contacts to bring up the privacy settings for that app.
Click the lock in the lower left corner of the preference pane and enter your admin credentials. Then, simply uncheck the checkbox next to each app you want to revoke Contacts privileges from. Go ahead and quit System Preferences when done.
When one of the affected apps asks you again whether it can access your info or not, you can disallow from there. The whole point of this is to help you be more aware of what is being used on your system, thus increasing the security of your Mac. Bravo, Apple!
