Firmware update enables 'Power Nap' feature for Mid-2011 MacBook Airs

A firmware update pushed out by Apple on Wednesday enables the Power Nap in certain MacBook Air models that were promised the feature but found it missing when OS X Mountain Lion launched earlier in the day.

Apple rolled out the new firmware via Software Update in conjunction with the release of OS X Mountain Lion after the company previously noted Power Nap may not be able to work on certain Macs without such an update.

First outlined in June during Apple's WWDC, Power Nap enables Macs to stay up to date and allows for the automatic backup of data while the machine is sleeping. The automatic refreshing of data, including Time Machine and iCloud syncing, is reportedly silent and power efficient though compatibility is limited to Macs with solid state drives like the MacBook Air.

When OS X Mountain Lion was released earlier in the day, some MacBook Air users noticed that the touted feature was missing. The problem has apparently been remedied in the Software Update which is for some "MacBook Air SMC Firmware Update 1.5 for the MacBook Air."

After the firmware is download through Software Update the Power Nap feature can be found in the Energy Saver pane in System Preferences.

I am running a 15" MBPr and there are no updates available and Power Nap is not available for me. Anyone have a direct link to the firmware update?

Power Nap for MBP with Retina is still "coming soon" according to Apple. I guess we'll just have to wait a little bit longer!

I wonder if a third party company will bring out a utility for this for those of us with slightly older MBPs with self added SSD drives. I am thrilled with AirParrot which has added the missing Air Video play to my mid 2010 MBP i7 running Mountain Lion. P.s. Is any one else finding their iPad is actually getting worse at auto spelling correction or is it just me?
