In the wake of an enormous operating system release, you can always expect some updates.
Per MacRumors, Apple on Friday rolled out a firmware update for the 15-inch MacBook Pro with Retina display enabling Mountain Lion’s new Power Nap feature two days following the new operating system’s release.
The update, a 190 kilobyte download entitled “MacBook Pro Retina SMC Update,” comes on the heels of a Thursday firmware release which brought the same functionality to mid-2011 MacBook Airs and is available via OS X 10.8’s Software Update feature and enables the new Power Nap feature that comes with Mountain Lion.
Limited to newer MacBook Air models and the MacBook Pro with Retina display, Power Nap keeps Macs up to date and allows for the automatic backup of data while the machine is sleeping. The automatic data-refreshing service, which handles Time Machine and iCloud syncing, is both silent and power-efficient.
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.
