  • Graham Miln Level 1 Level 1

    My Mac Pro (Early 2009) is suffering from the same kernel panics; this began with OS X 10.8.0, aka Mountain Lion.


    The Mac Pro has two Apple displays connected. Each display is connected to a separate NVIDIA GeForce GT 120 512MB card.


    The bug has been reported to Apple as rdar://12034966 (

  • kevloucat Level 1 Level 1

    Wow. Thanks for the info. So this thing has gotten official.

  • Graham Miln Level 1 Level 1

    Every time your Mac has a kernel panic, be sure to report the problem to Apple on the next start-up. Every report is important. A growing pile of reports help Apple's managers justify engineering time needed to fix the problem.


    All your previous kernel panic log files can be found within


         Applications > Utilities > > System Diagnostic Reports


    Originally I suspected this problem was a one off hardware fault. However, seeing multiple near identical panic logs suggests a software error.

  • kevloucat Level 1 Level 1

    Yeah, I found about all of these reports when I posted about this kernel panic earlier last week. I got some helpful responses, but nothing was solved. Most of the people got too stumped to help. They did mention these records. I disabled Logmein, which seemed to be the problem, and it was showing up in the list, but when I disabled it, AppleHWSensor seemed to be the culprit. I reinstalled that extension after hearing from some people that it was too important. I don't like monkeying with the brain of the Mac, that's for sure.


    I DO send all the reports to Apple, so I've been on top of that.


    Hopefully something will come out of this. I tried to look about upgrading my video cards, but couldn't find any options (larger memory) for my 2009 Mac Pro. Wouldn't mind getting more video memory if my machine could handle it.


    Thanks again for the info!

  • Grant Bennet-Alder Level 9 Level 9

    Maybe an upgrade to an Apple-firmware 5770 or 5870 would solve many problems at once. Either of those cards can handle up to 3 displays, if you play the adapter game just right.

  • kevloucat Level 1 Level 1

    Found the 5770 for about $250 on Not too shabby.


    I'm going to take the advice earlier and disconnect the NVIDIA GeForce GT 120s individually to see if that stops the kernel panics. Seems like everything comes back to that.


    The idea of one 1GB video card sounds pretty nice.



  • Graham Miln Level 1 Level 1

    kevloucat, please keep us informed about what you find after removing the GeForce GT 120 cards individually. I will be interested to know if this problem continues with a single graphics card.


    Be sure to check that any replacement graphics card comes with an Apple compatible firmware installed.


    It is safe to rule out non-Apple extensions as a problem; I have no third party kernel extensions on the Mac Pro that suffers the panics.


    I have begun to associate the panics to when I am using Safari (v6.0/8536.25). Panics have yet to occur while I am working with other applications.


    Are you seeing any pattern in what applications are front most at the time?

  • Grant Bennet-Alder Level 9 Level 9



    All your Panics are occurring in the latest NVIdia GeForce display driver.


    Retina MacBook Pro users are complaining of a kernel panics in the newest GeForce driver. Anecdote suggests there may be a memory leak in the driver. Apparently it is made MUCH worse by any but the latest version of Chrome.


    I suggest you do the following as a temporary work-around:


    1) if you use Chrome, get the latest version.


    2) after long use, do a Restart. At least daily, possibly more often.

  • Grant Bennet-Alder Level 9 Level 9

    10.8.2 is out as of today. It may contain an improvement to that driver.


  • Graham Miln Level 1 Level 1

    The kernel panics continue with OS X 10.8.2 (12C54).


    • The problem is not unique to the Chrome browser.
    • The panics occur too soon after boot to be memory exhaustion - additionally, the kernel task is not growing beyond reasonably memory sizes when viewed by Activity Monitor.


    The panic log now includes better information suggesting the root cause:

  • Grant Bennet-Alder Level 9 Level 9

    Graham Miln-


    That is a new kind of Panic I have never seen reported here.


    Be sure to send that report to Apple.


    Could you please also post the complete panic log here (or start a new thread), so we can all use it for reference:


    Mac OS X: How to log a kernel panic

  • kevloucat Level 1 Level 1

    Looks like the software update didn't fix it. But I removed one if the GT120s and worked about 4 hours with no panic. Looks like that could be the culprit.


    I'll give it a few more hours.

  • Pierre Igot Level 1 Level 1

    I have the exact same machine (2009 Mac Pro with 2 Ge Force GT 120 cards) and the exact same problem. It appears that I might have found a solution. It's a hack, but until Apple releases an official fix (which could take a while), it might help you eliminate the kernel panics without having to revert to 10.8.1:


  • kevloucat Level 1 Level 1

    Wow. Just read this over. It's worth a try before I spring for a new video card. I still have the 2.3.4 version via Time Machine, so it's an easy replace.


    I'll give it a try. Thanks for the link!

  • kevloucat Level 1 Level 1

    Well, Betalogue was too good to be true. Followed the directions and the kernel panic happened again.


    Going to remove that video card again and give that another shot.
