Yesterday Apple released an update for the 2011 and 2012 MacBook Air to enable Power Nap, and today an update enabling the Mountain Lion feature has been released for the MacBook Pro with Retina display. Power Nap is one of the 10 essential Mountain Lion features and it allows your Mac to download Mac App Store updates, OS X updates, email, sync with iCloud, back up to Time Machine, and more all while in sleep mode.
This update fixes several sleep/wake issues to improve the stability of MacBook Pro with Retina display (Mid 2012) computers and is recommended for all users running OS X v10.7.4. It also enables Power Nap support for users running OS X v10.8 or later.
To get the update, head to the Mac App Store software update tab. Lion users will also benefit from the update as well, and can find it in Software Update.
Mountain Lion has been out for a couple of days, available for just $19.99 on the Mac App Store. Judging by our server logs, many of you have already upgraded to the latest Apple OS. For those still on the fence about what exactly you're getting for your Jackson, we figured we'd explain the top user-facing features of OS X 10.8. Sure, Apple is touting that Mountain Lion includes over 200 new features, but redesigned scroll bars are hardly anything to get excited about. Here are the Mountain Lion features that prove that $19.99 is a steal.
