Download OS X 10.8 Mountain Lion DP 4 – Developer News

Apple has confirmed availability of a fourth developer preview for Mountain Lion testers, ahead of the scheduled public debut in July. Developers are told to leverage the new features in their own applications.

Over at the News and Announcements section on Apple’s Developer site, the Mac maker tells programmers to “Take advantage of new features in OS X Mountain Lion, like Game Center, Notification Center, Documents in the Cloud, advanced security features, and Facebook integration.”

These are just a few of the new features implemented by Apple in Mountain Lion, a 20-dollar upgrade for Snow Leopard and Lion users next month.
