Retina MacBook Pro Gets Power Nap Update

Posted on July 27, 2012 by

Apple released an SMC update enabling Power Nap support for the MacBook Pro with Retina display. Power Nap is an awesome new feature in OS X Mountain Lion that lets your Mac stay up to date while it sleeps. Power Nap requires a Mac notebook with SSD like the MacBook Air (Mid 2011 and 2012) and MacBook Pro (Retina, Mid 2012).

Power Nap does more when your Mac is plugged in to an AC outlet

When your portable Mac is connected to a power source, it also downloads software updates, makes backups with Time Machine, performs Spotlight indexing, and can continue Mac App Store downloads.  It also updates Help Center.


When Power Nap is doing its job, the system sounds are silent and no lights or fans come on.  When your Mac wakes up, it’s good to go.
