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.
