Apple has posted OS X 10.8.2, a major update for Mountain Lion. The main addition is Facebook integration, which was originally expected at the launch of the OS. The feature allows not only quick sharing of links and photos, but also the ability to receive Facebook alerts in the Notification Center. More hooks extend into Game Center, where people can "Like" games, and use Facebook as a source for friend recommendations. Scores can now be shared to Facebook, Twitter, Mail, or Messages; friends can be challenged to beat scores and achievements.
