Apple Begins Testing OS X 10.7.3 With Developers

As noted by AppleInsider, earlier today Apple seeded the first version of Lion’s next update – 10.7.3 – to registered Mac developers. The build, labelled 11D16, is available both for Lion and Lion Server configurations.

According to developers familiar with the release, the focus areas for 10.7.3 testing are iCloud document storage, Address Book, iCal and Mail. Apple warns developers that by installing the 10.7.3 seed, they will be unable to revert back to older versions.

The latest version of OS X Lion, 10.7.2, was released on October 12th and delivered support for iCloud on the desktop, alongside other new features, fixes and optimizations. As with 10.7.1 before, 10.7.2 was released both through Software Update and the Mac App Store. If Apple’s testing period for 10.7.2 (the OS was first seeded in late July) and 10.7.1 release are of any indication, 10.7.3 testing should require at least one month before it goes public.
