The first beta of Mac OS X 10.8.4 (build 12E27) has been released to developers. It apparently includes only minor bug fixes, and no new features or major fixes.
Apple indicate that the this beta focuses on the same areas as the previous one – graphics drivers, Wi-Fi and Safari. As with other OS X betas, 10.8.4 is intended for members of the Apple Developer program, not the public.
This beta arrives two weeks after OS X 10.8.3 was release to everyone. That had bigger fixes and improvements like Boot Camp support for installing Windows 8, utilizing the Mac camera for redeeming iTunes gift cards, and Safari 6.0.3.
