Apple has started seeding the fourth beta build (10J855) of the upcoming Mac OS X 10.6.7 to developers just a week after they seeded the previous beta build. All four builds have been released within the last four weeks, so it seems Apple is working together with the developers in order to get this next update for Snow Leopard ready for the public pretty quickly. This new build apparently contains no documented known issues, which likely indicates they’re getting very close to a public release.
Apple is continuing to ask developers to focus their testing specifically on Airport, SMB, Bonjour, the Mac App Store, and graphics drivers. The newest build has grown by over 35MB at a current total of 412.6MB, the entire combo build weighing in at 1GB.
If you’re a developer, you can get yourself a copy of 10J855 now at the Mac Dev Center.
