rMBP Doesn't Wake Up From Sleep After Upgrading to ML

Question

It is the second time that my rMBP doesn't wake up from sleep. The only application that I've recently installed are Alferd and BetterTouchTool - Could it have something to do with that?

In addition it happened twice only after long time sleep of like 8 hours - if I sleep the machine now and wake it after 2 minutes it wakes up perfectly.

Do you have any ideas what can cause this? In Lion I had no problems.

EDIT: Apple released the following update

hopefully this will fix the problem.

EDIT: Nope, didn't help.

EDIT: I freshly installed ML again, which fixed my problem. I have added an answer below, please read it.

Answer 1

Not a solution, unfortunately, but a report of the same problem with a MacBook air (mid 2012). It was running Lion without a glitch, but ever since I upgraded with ML, I can't wake it up from sleep (closed lid) when I try to use it back in the morning. To get control back over the machine, I need to do a SMC Reset (Left Shift - Option - Control + Power button at the same time) for a hard reset. I tried to install the SMC update mentioned in the EDIT, but the MBair refused to accept it. Still at a loss… I have unchecked the Power Nap feature to see if it would make a difference, but to no avail.

OK, finally a solution that worked.

I formatted my partition and freshly installed ML, which fixed my wakening problems. Here is a tutorial on how I freshly installed ML: How To Fresh Install ML
