Apple Enables 'Power Nap' for Retina MacBook Pro With SMC Update

NewImage
Apple has issued a system management controller (SMC) update for the MacBook Pro with Retina display, enabling Power Nap support in OS X Mountain Lion.
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 is available via Apple's software download webpage, Software Update for those under OS X Lion and via the Mac App store for those with OS X Mountain Lion installed.

Umm... This is not a fix. This is a firmware update that enables Power Nap. It doesn't matter when you upgrade to Mountain Lion, you'll still have to update your firmware to use Power Nap.

So, I have already downloaded and installed the SMC Update. On my Retina MacBook this caused a major pink screen issue. I have posted on the Apple Forums about it here: https://discussions.apple.com/thread/4146958

If anyone has any thoughts or has a similar issue, please respond to that thread.

Maybe try disabling all that extra crap you have running first.

If only you had read the warning before you applied the update you would've been prepared for that :p

Wonder how long it'll take someone to figure out a way around to enabling it :cool:


It relies on hardware to support this feature... so... long.
