OS X 10.8 Mountain Lion Developer Preview 3

OS X Mountain Lion (version 10.8) is the ninth and next major release of OS X, Apple's desktop and server operating system for Macintosh computers. OS X Mountain Lion was announced on February 16, 2012 and is scheduled for a release in summer (winter in the Southern Hemisphere) 2012. It will gain additional features from iOS, some of which were previously introduced to the Mac in OS X Lion.
In contrast to prior versions, Apple consistently refers to OS X Mountain Lion as "OS X" rather than "Mac OS X".
