Apple seeds second OS X 10.8.4 beta with no known issues, reactivates App Store updates

Apple on Tuesday rolled out OS X 10.8.4 beta build 12E30 to developers, with the biggest change being the return of Mac App Store downloads

The new build release come a little over one week after Apple issued the first Mountain Lion 10.8.4 beta in early April.

According to people familiar with the new build's release notes, Apple has not modified the areas of focus since the first beta, asking testers to focus on Wi-Fi, Graphics Drivers and Safari.

Unlike the first build, Apple is now offering software updates through the Mac App Store, a feature first seen with OS X 10.8.3 beta builds.
