For the fourth consecutive week, Apple has issued a beta of Mac OS X 10.6.7, the next update to its Snow Leopard operating system, to developers, who have been asked to focus testing on the Mac App Store.
Apple released build 10J855, available either as a 1GB combo update or 412.6MB delta update, on Thursday. According to people familiar with documentation for the update, there are no known issues with the build.
The first beta of Mac OS X 10.6.7 was seeded on Jan. 20, with updates following roughly within a week of the previous one for the past month.
Developers have been encouraged to focus on the Mac App Store, Airport, Bonjour, SMB file sharing and Graphics Drivers, said those familiar with the beta.
It is unclear what new features, if any, will be included in Mac OS X 10.6.7 when it is released to the public, but the launch of the Mac App Store last month is expected to be the last major feature added to Mac OS Snow Leopard.
Apple announced last October its plan to release Mac OS 10.7 Lion this summer. The next major update to its flagship operating system will include features brought over from iOS to the Mac platform, such as a home screen, full-screen applications and new multi-touch gestures.
