Just one week after releasing the 7th beta build of OS X 10.8.3 to developers, Apple has now seeded an eighth build to devs. The build number comes in at 12D58, and Apple lists no known issues with the update. Developers are once again asked to focus on AirPlay, AirPort, Game Center, Graphics Drivers, and Safari as they test their apps against the new build.
This is likely to be among the very final stages of testing for the OS X 10.8.3 update, which has been in testing with developers since late October of last year. The update is available now through Software Update for those already testing 10.8.3, as well as direct download from Apple’s Mac Developer Center for paid Mac devs.
