Apple has just released a new build of OS X 10.8.4 to registered Mac developers today, just over a week after seeding the previous build. The new version bears a build number of 12E33a, and as with the previous two updates, Apple continues to ask testers to focus on Wi-Fi, Graphics Drivers, and Safari.
The update weights in at 828.43MB for the Combo update, and 354.19MB for the delta version, and is available now through Apple’s developer portal. The previous build of OS X 10.8.4 confirmed that Apple is planning to bring super-fast 802.11ac WiFi support to future Macs.
