Not content merely to update one of its flagship operating systems on Wednesday, Apple released an update to OS X Mountain Lion, too: version 10.8.2.
New in 10.8.2 is support for Facebook, matching the similar feature launched in iOS 6. Desktop apps that need your Facebook credentials will now be able to access them from your settings in System Preferences, notifications from Facebook will appear in Notification Center, and your Facebook friends contact information will appear in the Contacts app.
Game Center scores some updates, as well. You can share your high scores to Facebook, or via Twitter, Mail, or Messages, and you can also challenge your Facebook friends to beat your score from within the app.
And, at long last, iMessages sent to your iPhone number should appear in the Messages app on your Mac. FaceTime calls to your phone number should ring on your Mac, as well.
Other new features include Power Nap support for the MacBook Air (Late 2010), support for sending passes to Passbook on iOS 6, the ability to share Reminders lists, and new sorting options for Notes.
Save As devotees, take note: 10.8.2 adds an option to discard the changes in the original document when you use the recently-restored Save As option. That addition restores the original Save As behavior to which Mac users were long accustomed before the feature first vanished in Lion, and reappeared with different functionality in the original Mountain Lion release.
Twitter notifications are handled better in Notification Center. And Google searches from the location bar now support SSL as well.
Mac OS X 10.8.2 is available via the Mac App Store. If history is a guide, it will soon be available as a direct download from Apples website, but it isnt there at this writing.
