Apple recently seeded build 12E33a of OS X 10.8.4 maintenance update to developers. The latest beta comes just a little over one week after the build 12E30, which went out for testing in early April. The latest build of Mountain Lion comes with no known issues and once again asks testers to focus on Wi-Fi, Graphics Drivers and Safari.

In the previous build, build 12E30, a code was discovered which mentioned 802.11ac “Gigabit” wireless protocol, suggesting that Apple could be making preparations to launch compatible hardware in the near future.

The recently seeded beta build is the third beta build release for OS X 10.8.4. Developers can access the most recent seed through the Mac App Store’s Software Update mechanism, a feature that was first seen with OS X 10.8.3 builds.
