Apple Launches OS X Mountain Lion in Mac App Store

Apple today released OS X Mountain Lion, the ninth major release of the company’s desktop operating system. It’s now available as a download from the Mac App Store for $20 (or for free if you bought an Apple computer on or after June 11).

Apple says that Mountain Lion includes “more than 200 innovative new features,” including iCloud integration, the new Messages app (which I’ve thoroughly enjoyed using in beta), AirPlay Mirroring, and Game Center. You might notice that most of these new features blur the line between OS X and iOS, Apple’s mobile platform. That is, of course, the idea: Apple is gradually unifying the two systems.

Most reviews for Mountain Lion are positive, with a standout remark being the bargain bin price point. Jim Dalrymple of The Loop calls the upgrade “definitely worth it,” MG Siegler at TechCrunch calls the OS “pretty fresh,” and Nilay Patel of The Verge says the system is “faster and smoother.”
