Apple releases developer preview of OS X Mountain Lion

Thu, Feb 16, 2012


Apple today released a developer preview of the next iteration of OS X, dubbed Mountain Lion. The new OS contains over 100 new features and is available as a developer download today. The release of Mountain Lion further blurs the lines between OS X and iOS, and thankfully, Apple isn’t blindly incorporating every iOS feature into OS X, but rather, only those features that make sense to add.

Mountain Lion introduces Messages, Notes, Reminders and Game Center to the Mac, as well as Notification Center, Share Sheets, Twitter integration and AirPlay Mirroring. Mountain Lion is the first OS X release built with iCloud in mind for easy setup and integration with apps. The developer preview of Mountain Lion also introduces Gatekeeper, a revolutionary security feature that helps keep you safe from malicious software by giving you complete control over what apps are installed on your Mac. The preview release of Mountain Lion is available to Mac Developer Program members starting today. Mac users will be able to upgrade to Mountain Lion from the Mac App Store in late summer 2012.

“The Mac is on a roll, growing faster than the PC for 23 straight quarters, and with Mountain Lion things get even better,” Apple Senior VP of Worldwide Marketing Phil Schiller said in a press release. “The developer preview of Mountain Lion comes just seven months after the incredibly successful release of Lion and sets a rapid pace of development for the world’s most advanced personal computer operating system.”

Mountain Lion presents notifications in an elegant new way, and Notification Center provides easy access to alerts from Mail, Calendar, Messages, Reminders, system updates and third party apps. System-wide Share Sheets make it easy to share links, photos and videos directly from Apple and third party apps. Twitter is integrated throughout Mountain Lion so you can sign on once and tweet directly from Safari, Quick Look, Photo Booth, Preview and third party apps. Mountain Lion also introduces AirPlay Mirroring, an easy way to wirelessly send a secure 720p video stream of what’s on your Mac to an HDTV using Apple TV.

Also on deck are hundreds of new APIs, tight Twitter and iCloud integration, a new graphics infrastructure, and a whole lot more.
