OS X 10.8.5 development is underway.
Per AppleInsider, Apple on Wednesday seeded the first OS X 10.8.5 Mountain Lion beta build to developers, with the latest maintenance update possibly looking to stabilize the operating system ahead of an OS X 10.9 Mavericks launch this fall.
Sources familiar with the beta, dubbed build 12F9, said Apple is asking developers to focus on existing Mountain Lion features, including Wi-Fi and graphics.
The latest beta comes two weeks after Apple issued the OS X Mountain Lion 10.8.4 maintenance update to Mac users, which brought Wi-Fi improvements, compatibility with Microsoft Exchange and a host of bug fixes.
Apple is expected to release the next-generation OS X 10.9 Mavericks this fall, and a preview has already been seeded to the development community.
If you’ve gotten your hands on this build and have any feedback to offer, please let us know in the comments.
