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.
One of the main new features of OS X Mountain Lion is Power Nap. Power Nap allows your SSD Mac to keep itself updated and synced to the cloud, even while it sleeps. While its a highly-touted feature of Mountain Lion, support for the 2011 and 2012 MacBook Air and the new MacBook Pro with Retina display was left out. Today, Apple released a download that enables Power Nap for the aforementioned MacBook Air units, with the promise that an additional download that'll enable the feature on the MacBook Pro with Retina display is "coming soon." You can get Mountain Lion now for $19.99 on the Mac App Store.
