Late last month, Apple released OS X Mountain Lion 10.8.2 build 12C35 to developers, and today, Apple has followed up with build 12C43. The quick turnaround of new beta releases indicates that Apple is moving quickly to have 10.8.2 ready for a public release. 10.8.2 includes Facebook integration and iMessage phone number merging, making it the iOS 6 compatibility release. With Apple’s event happening on September 12th, and the iPhone 5/iOS 6 launch tracking a launch later this month, 10.8.2 will probably launch around that time as well.
