Apple today seeded a new version of Mac OS X 10.6.2, termed Build 10C540, to developers. The release comes one week after the release of the previous build.
As with the previous two developer seeds, Apple lists no known issues in the new build. Approximately a half dozen areas of change since the previous seed are documented, including fixes for issues related to AirPort on Apple's latest iMac models and VMware, as well as graphics-related issues affecting certain graphics cards and the Apple TV.
Mac OS X 10.6.2 reportedly addresses a serious bug involving Guest accounts that has resulted in some users losing all data from their regular user accounts. It also appears to bring full native support for Apple's new multi-touch Magic Mouse, allowing future purchasers of the mouse once the update is released to the public to skip the step of installing a separate software update to enable full Magic Mouse functionality.
Developer seeds of Mac OS X 10.6.2 have received significant attention this week after it was revealed that Apple had apparently disabled support for Intel's Atom processors that are power many netbooks modified by users to run OS X in a build released two weeks ago. Last week's released build, however, appears to have restored Atom compatibility, although the reasons behind the changes remain unknown.
