Those familiar with the latest build of Mac OS X 10.6.7 say it is known as 10J850, and was released late Tuesday. The delta update is reportedly a 376.9MB download.
Those people say Apple has asked developers to again focus their testing on the Mac App Store, as well as AirPort, Bonjour, SMB, and Graphics Drivers. The latest build has no known issues.
The last beta of Mac OS X 10.6.7, Apple's forthcoming maintenance and security update for Snow Leopard, was released just over a week ago. That build, dubbed 10J846, was a 372MB download that asked developers to concentrate on the Mac App Store — the only change from the previous build.
And less than a week before that, on Jan. 20, the first beta of Mac OS X 10.6.7 was issued to developers. None of the releases have reportedly contained any known issues.
