Just one week after the previous OS X 10.8.5 beta was unleashed on developers, Apple has now begun seeding their fifth OS X Mountain Lion 10.8.5 beta. The update bears a build number of 12F23 – just three builds newer than the previous build. The minimal change in build numbers, and the decrease in time between updates suggests that Apple is likely nearly ready to release the update to the public.
Apple is continuing to ask developers to focus their attention on Wi-Fi, Graphics, Wake from Sleep, and PDF viewing, Accessibility, and Mobile Device Management. The update is available through the software update tool in the Mac App Store for those who tested previous Mountain Lion betas, as well as for direct download from Apple’s Mac Developer Center.
