Apple released the first beta version of its OS X for Mac Mountain Lion 10.8.3 (build 12D32) yesterday, which we've been waiting for a while. Of course, only developers can access it at the moment.
In order to install it, developers must first download the utility OS X Software Update Seed Configuration. Apple also asked them to focus on AirPlay, graphics, AirPort and the Game Center.
Several bugs have already been spotted, including some display problems in certain languages ??or with the wallpapers. The Command + Tab shortcut may also pose some concerns.
