    Exact same type of thing here:

    BSD process name corresponding to current thread:


    Mac Pro, Earl 2009, 2x NVIDIA GeForce GT 120 512 MB, OSX 10.8.2, three monitors.


    However mine is only happening every few weeks, which makes it rather hard to track down. I'm suspecting it something to do with VRAM - some kind of video driver problem being revealed at random by particular usage patterns. I usually have lots of windows open, mostly Chrome.

  • Grant Bennet-Alder Level 9 (55,250 points)

    See Pierre Igot's previous posts on this thread. He cites a supplemental update for 10.8.2 that may help, and also a suggestion to use an older version of a particular driver is mentioned on his blog. Read everything before you do anything.

  • Pierre Igot Level 1 (15 points)



    I just went through the System/Library/Extensions/ folder and identified the kext files that might or might not have to do with our current predicament. My focus remains on these files:






    since they were the ones that were changed in OS X 10.8.2, when we started getting these KPs. But it could very well be that the problem is a complex one involving interactions between several different files, so who knows?


    Like I've said before, this bug is completely unpredictable and sometimes does not occur for days, then occurs several times in a single day, with no rhyme or reason. But it's really shaking my faith in the reliability of Apple's systems. It's unacceptable to have such a serious bug that remains unaddressed several months after it was first uncovered and after it's been a "known issue" for quite a while. I don't want to have to wait until 10.8.3 is out. I want a special fix for this particular problem NOW. This is a **crashing** bug that affects a number of people using their expensive machine perfectly normally, with no weird third-party interactions or incompatiblities.


    Apple is really dropping the ball here.

  • Pierre Igot Level 1 (15 points)

    Answers to your other questions:


    I don't think the CUDA updates do anything (good or bad). CUDA is only used by some specific applications. I had the KPs before I had even heard of CUDA, let alone tried to install it. (I did, just in case. Didn't make any difference.) The KPs don't require the use of CUDA. I don't think it's involved at all.


    As NVIDIA, I submitted a bug report directly to them back on Sept. 20 via Never heard a peep from them. Haven't tried the forums.

  • Dick Chanslor Level 1 (15 points)

    This seems not to be limited to the Mac Pro, because I have been experiencing similar kernel-panics on my iMac 24 inch (early 2009) which also has the NVIDIA Geoforce GT 130 graphics.


    All of my panic reports include reference to the "NVDAResman(8.0)" and the three files you mentioned above:





    I didn't notice the panics until sometime after the 10.8.2 update, and I'm not sure how many days after;  I don't remember when I installed 10.8.2. I believe the panics started after the iTunes 11 update, but not sure if that could be related.


    In the beginning, the panics only occurred with an automatic restart during cold startup in the morning, and (not watching the startup) I first noticed it when the alert to report to Apple appeared. On perhaps two other occasions, the panic occurred during other operations, once during Safari usage, and another while unattended. Both of these others also included an automatic restart.


    My troubleshooting is quite slow, because I can only reproduce the KP on demand in the morning after being shut down all night. I did reboot one morning from a Lion partition with no problem. Also, startup in Single User mode seems to work OK. I have two backup drives with 10.8.2, so I'm considering reinstalling 10.8 and updating only to 10.8.1, which never had this probem.


    So, I'm monitoring this discussion with interest. Appreciate your efforts.

  • Dick Chanslor Level 1 (15 points)

    Reinstalled Mac OS X 10.8. Updated to OS X 10.8.1. No kernel panics since.

  • Jsh111 Level 1 (0 points)

    For what its worth, my Mac Pro Mountan LIon freeze/kernel-panic nightmare is much worse when trying to run either VMWare or Parallels Windows VMs.  I've got 3 GT120s so tag this under the Mountain Lion cant deal with Mac Pros running multiple video cards files.

  • Dick Chanslor Level 1 (15 points)

    My kernel panics ceased after I cleaned out four years of dust and reseated RAM.

  • cryptomagic Level 1 (0 points)

    Pierre, I agree with your CUDA assessment.  Could you link me directly to your posting on the NVidia forum so I can add my 2 cents.  Perhaps a few more comments on that thread might wake someone up over there.


    FWIW, my panics are pretty spread out now.  Here is my complete history


    09.29.12 - KP every ~6 hours until I rolled back to 2.3.4 in /System/Library/Extensions/IOGraphicsFamily.kext

    10.11.12 - KP

    10.15.12 - KP

    10.29.12 - KP

    11.06.12 - KP so I upgraded NVidia drivers and installed CUDA package

    11.26.12 - KP so I updated the CUDA package again and I reverted to 2.3.5 of IOGraphicsFamily.kext

    01.02.13 - KP


    FWIW, I'm going to replace all my RAM in the next couple days as part of a system upgrade.  Maybe I'll get lucky like Dick?

  • Pierre Igot Level 1 (15 points)



    I didn't post anything on the forum, I only submitted a bug report at I had to register first and the bug report is tied to my account, so I don't believe I can give you access to it. It has a reference no of "120920-000178" and is dated Sept. 20, 2012. Still no response from NVIDIA, of course.


    You are lucky you're not getting more KPs. :-)


    I haven't had a single one since switching to connecting the two monitors to the same GeForce GT120 with a DVI-to-MiniDisplayPort adapter for the second one. Of course, it means I have half the VRAM I normally should have (there is a noticeable degradation in graphic performance) and I also feel that the GeForce card that is driving both monitors is now hotter and noisier :-(.



  • cryptomagic Level 1 (0 points)

    I post a second bug report #130118-000210


    That's a bummer having to put both screens on one card.


    I'm not totally out of the woods.  I seem to get a KP ever two weeks.  Today I gave my computer a tune up


    1. I popped out all 3 of my video cards, dusted them off and re-seated them. 
    2. I upgraded from 8G to 16G of RAM.
    3. I cleaned all the fan housings to be free of dust


    Maybe it will be happier after some love.

  • Pierre Igot Level 1 (15 points)

    I could probably live with one every two weeks. But two or more a day is not an option.


    I find it rather doubtful that clearing the dust would make any difference, as I haven't done any cleaning myself and yet with both screens on the same card (EITHER card), I get zero KPs.


    It's a software bug, and it won't disappear until Apple fixes its software. Given how long it's already been with us, the signs are not encouraging.


    Thanks for the updates.

  • Jsh111 Level 1 (0 points)

    I agree.  I've given up tinkering.  This is a software bug and no permutations of fiddling with settings will fix it.  I give apple until 10.8.3 to fix it.  Otherwise I sadly have to abandon OSX and go to Windows since I need multimonitor functionality.  Pretty depressing.

  • cryptomagic Level 1 (0 points)

    Hey, no fair dispelling my self-delusions.  After all Nvidia just sent me this nice email:


    Nvidia Submit Customer Care <>

    to chris


    Thank you for your submittal to the NVIDIA Product Feedback Page.

    We will carefully review your submission and may contact you for further information if needed as we attempt to reproduce your issue.

    I just want them to tell me if the C++ file that throws the exception is their's or Apple's

  • Arkange Level 1 (0 points)

    I have this KP with my Mac Pro and 3 monitors only when he wake up. Not all wake up but 2 or 3 times per day.
