Apple's OS X 10.8.2 arrives with Facebook in tow

Apple's iOS isn't the only thing to get an update this morning. Alongside iOS 6, Apple quietly pushed out 10.8.2, the second minor update to Mountain Lion since it was released in July.

Chief among the additions is integration with Facebook, a feature that was promised for a fall release when Mountain Lion first debuted earlier this year. Facebook users can share items directly from share sheets now, as well as in Notification Center, and sync up contacts from the popular social network.

The update also adds the Power Nap feature to late-2010 MacBook Air machines, and phone number integration for both FaceTime and the Messages app.

Not mentioned is any improvement to battery life times on Apple's portable machines. Testing of the pre-release version of 10.8.2 by the Mac Observer showed significant gains to running times, something that took a hit in 10.8.

Here's the whole change list:
