Apple on Tuesday released build 12E36 of the next OS X 10.8.4 maintenance update, with the latest beta bringing no known issues.
As with the last seed, which was released about a week ago, the newest build asks developers to focus on Wi-Fi, Graphics Drivers and Safari.
In the third build, dubbed 12E33a, a line of code was discovered pointing to the possible inclusion of speedy 802.11ac Wi-Fi in future Macs.
