The company run by Tim Cook and headquartered at 1 Infinite Loop, Cupertino, California, has rolled out new betas of OS X Mountain Lion and OS X Lion to developers, in anticipation of the iOS 6 release this month.

OS X 10.8.2 Build 12C50 includes features like phone number syncing, which means Apple will use this release to streamline iMessage and Facebook integration across all its products. In other words, OS X 10.8.2 will be a compatibility release.

But not only that, as the release notes say so much more about the second Mountain Lion maintenance update.

“The 10.8.2 update is recommended for all OS X Mountain Lion users and includes new features and fixes,” Apple states. One noteworthy addition is the Power Nap feature for Late 2010 MacBook Air models. This version of the ultra-thin notebook was previously not supported.

We’ll detail the rest of the changes in OS X 10.8.2 12C50 in a separate report later today.

Apple also seeded OS X Lion 10.7.5 build 11G54 to developers this week. This Lion release will also bring forth the aforementioned compatibility changes, as well as some specific fixes of its own.

Apple will hold an event today for the unveiling of its next-generation smartphone and, sources say, some iPods too.

The company will also be releasing iOS 6 shortly. With the iPhone 5 becoming physically available on September 21, as analysts predict, we can expect these Mac OS updates to arrive at least on that date, if not sooner.

The iOS 6 beta software and SDK continue to be available to iOS Developer Program members at developer.apple.com. Apple will be releasing the software as a free update for iPhone 4S, iPhone 4, iPhone 3GS, the new iPad, iPad 2 and iPod touch (fourth-generation).
