When Mountain Lion was launched back in July, Twitter was the only social network baked into Apple's newest operating system. At the time the company said Facebook would be integrated in a later update. Apple has released OS X 10.8.2 which finally brings Facebook integration to the operating system.
Facebook is now an option in Finder's share menu when you want to share a link or photo with friends. You'll also see your Facebook friends in Contacts, with contact information and profile pictures. Only a single sign-on is required and notifications of the popular social network now appear in Notification Center.
OS X 10.8.2 includes other updates as well, such as support for Power Nap on the late 2010 Macbook Air, new dictation languages and support for receiving iMessages and FaceTime calls sent to your cell phone number. There's a new shared Reminders list and notes can now be sorted by title, edited date and creation date.
The newest update also fixes some problems, although the reported battery drainage issue is not listed in Apple's documentation. According to Macobserver, who ran some tests on developer builds of 10.8.2, the update should fix the battery issues which plagued Mountain Lion since its launch. There are also firmware updates for the latest Macbook Air and (Retina) Pro.
All other changes and features can be found at Apple's support page.
