OS X 10.8 Mountain Lion Golden Master seeded to developers

Apple on Monday seeded what is intended to be the final test version of its OS X 10.8 Mountain Lion to developers with no known issues, meaning that the next-generation operating system is all but complete and set for imminent launch.

Apple's Mountain Lion GM signals the final stage of software development for the next-generation OS which is expected to be ready for public consumption later this month unless developers find any issues with the finalized build.

A near-final build of Mountain Lion was made available to developers at the start of Apple's WWDC 2012 in June and included previously unannounced features like voice dictation and an energy-efficient Power Nap mode which automatically refreshes data on the second-generation MacBook Air and new MacBook Pro with Retina display. Tighter iCloud integration, offline webpage viewing in Safari and Messages are also in tow for the next-generation OS X.

Alongside Mountain Lion's over 200 new features is a substantial security system that regularly checks-in with Apple's servers to ensure that the latest patches and updates are installed on a user's Mac. The automated system could be a result of the highly-publicized Flashback Trojan that reportedly affected some 600,000 Macs worldwide.
