• Power Nap Feature Brought to Retina MacBook Pro with New Firmware Update

    Apple recently rolled out a firmware update for the 15-inch MacBook Pro with Retina display enabling OS X Mountain Lionís new Power Nap feature, just like they did previously for the MacBook Airs.

    Limited to newer MacBook Air models and the MacBook Pro with Retina display, Power Nap keeps Macs up to date and allows for automatic backup of data while the machine is sleeping. The automatic data-refreshing service, which also handles Time Machine and iCloud syncing, is both power-efficient and silent. Appleís website describes the feature as seen below:

    Power Nap. Mac stays up to date, even while it sleeps.

    When your Mac goes to sleep, it still gets things done with Power Nap.3 It periodically updates Mail, Contacts, Calendar, Reminders, Notes, Photo Stream, Find My Mac, and Documents in the Cloud. When your Mac is connected to a power source, it downloads software updates and makes backups with Time Machine. While all that updating is going on, the system sounds are silent and no lights or fans come on, so nothing disturbs you. And when your Mac wakes up, itís good to go.
    From Appleís release notes for the update:

    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.
    The update can be found in the Mac App Store while the settings for the Power Nap feature can be found in the Energy Saver pane of System Preferences.

    If you arenít sure if your Mac is eligible for the update, check (and download if appropriate) from the information below:
