Just one month after debuting OS X 10.8.4, Apple seeded the first beta build of OS X 10.8.5 Mountain lion to developers. The latest maintenance update seeks to possibly stabilize the operating system ahead of an OS X 10.9 Mavericks launch this fall. Apple has asked developers to focus on existing Mountain Lion features including Wi-Fi and graphics as part of the current beta build, dubbed build 12F9.

The latest beta comes just 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. The Cupertino California company 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.
