As Mountain Lion Crosses 3M Downloads in 4 Days, Apple Deems The OS “Most Successful OS X Release” Ever

Despite early hiccups Apple’s latest OS X release was downloaded more than 3 million times during its first 4 days of availability. The $20 upgrade brings a host of new features to compatible Macs including Airplay Mirroring, Game Center, system-wide sharing, and beefed-up iCloud integration, which now syncs iWork documents, notes, and reminders.

While Apple doesn’t speculate the reason for the huge download numbers, several factors likely led to the quick adoption rate. First, Apple priced OS X 10.8 to move. At only $20 the new operating system is a rather good bargain even if it doesn’t boast a lot of new features. Apple also made upgrading to Mountain Lion rather easy, which also likely led to more users jumping onto the system.

Thanks to the Mac App Store, upgrading to OS X 10.8 is downright easy. Users simply buy the new OS as if it was another application. From there, the update downloads in the background and prompts users to restart the system when its ready to install. It’s as painless as a system update.

“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 said in a released statement today.

Mountain Lion was released last Wednesday on the Mac App Store for just $19.99. Read our review here.
