Just over a week following the previous build, Apple has seeded OS X Mountain Lion 10.8.4 build 12E47 to registered Mac developers. The update is available via the Mac App Store for developers and should be on the Mac Developer Center shortly. Apple, once again, tells developers to focus on WiFi performance, Safari, and Graphics Drivers…

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!
