Following the most recent build just over a week ago, Apple has seeded another build of the upcoming OS X 10.8.4 to registered developers.

The new build comes in at build number 12E33a, and Apple asks developers to, again, focus on Safari, WiFi, and Graphics Drivers.

We previously reported that OS X 10.8.4 has hooks to support faster, 802.11ac WiFi connectivity. 

Thanks, D!
