Continuing their abnormally extensive testing for the upcoming OS X 10.8.3 update, Apple today seeded yet another build to developers today – their 13th build since testing began last November. The latest update comes just 5 days after the previous build, bears a build number of 12D76, and Apple again lists no known issues with the update.
As with previous builds, Apple once again asks developers to pay attention to AirPlay, AirPort, Game Center, Graphics Drivers, and Safari when testing their apps against the build, and exploring it in general. The update is available now through Software Update for users already using a beta build, as well as direct download from Apple’s developer page.
It’s unclear exactly what is taking Apple so long to release this update – I’ve never seen a “minor” OS X update go through 13 separate developer betas, or endure such an extremely long period of testing. Either Apple is stalling for some reason, or there are some major problems with OS X Mountain Lion they’re trying to tackle!
