A week following the previous build, Apple has released build 12E52 of the OS X Mountain Lion 10.8.4 beta to developers. Apple, once again, asks developers to focus on WiFi, Graphics Drivers, and Safari.

iPad Air 2

We previously noted that 10.8.4 includes support for Mac computers with 802.11ac WiFi chips.

While 10.8.4 is a minor update to OS X Mountain Lion, Apple also has a major release launching in the next couple of months. We previously reported that OS X 10.9 will include an enhanced Finder, much improved multiple-monitor support, a new version of Safari, and various other features from iOS.

Thanks, D!
