    Rob, that was exactly the message I was getting, I too had the NVIDIA GeForce GT 120 512 MB.

    Drivers updated now, I look forward to pouring thanks and praise on you after some sleepy hours.


    Chet, for what it's worth, I was experiencing the problem with wake for ethernet OFF

  • tobystokes Level 1 Level 1

    Just a further note to say that updating the graphics card driver did solve the problem.

    Rob, you're an absolute legend for tracking that down!


    Given that it's a standard graphics card supplied by Apple, not third party software, I do hope that the driver update gets bundled into a system update soon.

    With "wake on LAN" off everything seems to be fine. At least until Apple will address this issue with 10.8.3     


    : o )

    The driver update worked for me and my early 2009 Mac Pro. Thanks for researching this. Makes you wonder why Apple couldn't have assigned an engineer to do what you did.



  • thehypermonk Level 1 Level 1

    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.

    As Chet Rindfuss, my MBP has 9400m GT and 9600m GT GPU's. I didn't pay attention to if the problem happens on both, but, when on high-performance (9600m GT) it does freeze, it gets very hot and the fans are full speed.


    The problem started with 10.8.2.

  • Chet Rindfuss Level 1 Level 1

    I have filed a bug with on this issue. Hopefully there will be a fix soon.

  • dark_sat Level 1 Level 1

    I hope they do. I'm actually surprised that my mbp never turned off due to overheating. Last time (yesterday), it was running like this for about 4 hours.

  • JohnnyGTO Level 1 Level 1

    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/ from my backup of LIon.

  • mindyb Level 1 Level 1

    Thanks for figuring this out, Rob (Bonfire), and taking the time to post how you found it and how to fix it. This has been driving me nuts. Your advice solved my problem.

  • fgersch Level 1 Level 1

    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

  • faneuil Level 1 Level 1

    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.



  • faneuil Level 1 Level 1

    this is the driver I used - I have a Mac Pro "early 2009"

  • faneuil Level 1 Level 1

    well slight success -- I followed the link on that driver page to this alternate driver


    and now the mac wakes from sleep. for now.

    will report back with for details
