Mountain Lion’s Power Nap Feature Brought To MacBook Air With New Firmware Update

Mountain Lion’s Power Nap Feature Brought To MacBook Air With New Firmware Update

Apple unveiled Power Nap in Mountain Lion during the WWDC conference in June.

Can’t find Mountain Lion’s Power Nap feature anywhere on your MacBook Air? Apple has issued a new firmware update to bring the feature to 2011-2012 models. In case you didn’t know, Power Nap is a system management feature in Mountain Lion that silently fetches your emails, iCloud data, software updates, etc. while your Mac sleeps. For Power Nap to work, your Mac must be connected to a power source. The Mountain Lion feature works only on Macs with an internal SSD drive, like the MacBook Air and mid-2012 MacBook Pro models.

Power Nap doesn’t seem to be included on all Macs running the newly-released Mountain Lion OS, but this new firmware update should restore any issues for MacBook Air users.

Many MacBook Pro with Retina display users (myself included) don’t have Power Nap under the Energy Saver settings in System Preferences either. While some have said that performing a clean install of Mountain Lion re-adds Power Nap on the mid-2012 MacBook Pro, results appear to be mixed. If the lack of Power Nap on other Mac models is indeed a widespread enough issue, expect Apple to release more firmware patches for Mountain Lion soon.

    “For Power Nap to work, your Mac must be connected to a power source.”

    Wrong. I installed the firmware update and now when I go into Energy Saver preferences it gives me the option to use Powernap when plugged in AND when using battery power.

    Will my MBP early 2011 get this feature? I don’t see it after the upgrade.
