If you haven't upgraded your Mac to Mountain Lion yet, don't be surprised if you find yourself the only one who hasn't done so among your Mac-using friends. In a statement released today, Apple revealed that three million copies of its newest operating system have been downloaded over the course of four days, leading the company to claim that it's the "most successful [OS X] release ever."
Apple's newest big cat adds features straight from the iPhone and the iPad to your Mac, including iMessage, Notification Center, and voice dictation. Installing it is easy as pie: Simply look for Mountain Lion in the Mac App Store, buy your copy for $19.99 — or get it for free if you bought your Mac on or after June 11, 2012 — and download it. Just be warned that the file is pretty huge so it may take you a while to get it.
