Mountain Lion already Apple's most successful release.
Apple this week announced that the latest version of OS X was downloaded three million times in the span of four days. This makes it the most successful OS X release in the company's history.
"Just a year after the incredibly successful introduction of Lion, customers have downloaded Mountain Lion over three million times in just four days, making it our most successful release ever," said Philip Schiller, Apple's senior vice president of Worldwide Marketing.
Mountain Lion was first revealed in February of this year with Apple offering a "near final" release version of Mountain Lion for developers in June at its annual WWDC conference. Mountain includes more than 200 new features including the Messages app; Notification Center; system-wide sharing, which allows you to share photos, videos and other files over third party services at the click of a button without switching apps; Dictation; Power Nap, which keeps your computer up to date while sleeping with auto refreshes of Mail, Contacts, Calendar, Reminders, and Documents in the cloud; AirPlay Mirroring; Game Center; and Gatekeeper, a security setting that allows you to set your computer so that it will only accept software downloaded from the Mac App Store, or from the Mac App Store and identified developers.
Mountain Lion was released July 25 and is priced at $20. It's version 10.8 of Apple's OS X operating system.
