Problem with waking from sleep with 10.8.2

My Mac Pro (early 2009 2.66 GHz Quad-Core Intel Xeon) won't wake from deep sleep after installing OS X 10.8.2 . I have the default setting set for sleep. The only way to "wake" the machine is to hold the power button down to shut down and then restart. I've reset NVRAM (pram) and tried removing power cable. Nothing helps.

Mac Pro, OS X Mountain Lion (10.8.2)

Rob - thank you so much for digging this up and finding a solution.....I did the Nvidia update and for the first time since moving to ML, my 2009 Mac Pro Nehalem machine woke up from sleep fine this morning after I left it in sleep mode all night 🙂. Can't thank you enough, I had tried so many things and not to mention the amount of time I spent researching this issue over the last month. Thank you, thank you, thank you!

Just a quick comment to Rob:


You mentioned that you were annoyed that they were asking you to pay for support. I was digging around when I first ran into this problem, and you do indeed have 90 days of free support with your purchase of Mountain Lion. Here it is from their website: "OS X Mountain Lion purchased from the Mac App Store includes complimentary support for the first 90 days of product ownership."


It is annoying that you'd have to ask, but they should certainly honor the 90-day OS support if you mention it.

I wanted to point out two things, first Rob's Nvidia driver fix worked on my Mac Pro4,1 with dual GeForce GT 120s.


Second I just realised that it seemed to also fix my 2/3 monitor wake up issue were when the monitors did wake from sleep one often was not recognized and I'd have to reboot to get all three up. Of course Mountain Lion doesn't allow Display to "detect displays" any more... progress?


I finally got the Show Display and resolution picking back by grabbing HD/Library/CoreServices/Menu Extras/Displays.menu from my backup of LIon.

I'm in exactly the same position.

I'm going to give this a go. I'll guess I'll know in a couple of hours, although it sounds like a safe bet.


I am about sick of Apple neglecting pro users. I really don't want to have to look at another platform but if I want support and a chance of a new machine anytime soon I'll have to!


Thanks Rob

Well - Ever since ML upgrade I have had ntermittent 'comatose' mac problems (mac pro 2010), two GT120 cards.


I followed this thread's tip to update the nvidia drivers and the problem was no longer intermittent -- it was permanent!

Now ever time I put mac to sleep it is unwakeable.
Definitely driver related it seems.

Wake on LAN on/off: no difference. comatose.


Help. At least the irregularly regular problem is now regularly regular. IE -- broken!


apple please help.

Early Macbook Pro 2009 same issue. Have reinstalled Mountain Lion, set wake up to 25, downloaded new Graphics update, SMC Pram done it all, was running fine for about a week, and now it's doing it all again sigh..and not only doesn't it wake up the entire system is running slow and fans are running high. I'm going to delete the Cache and Cookies again to see if that helps and to a SMC reset.
