I'm running 10.8.4. Safari is completely useless, as it crashes my entire MacPro, approximately 10 minutes after launching it. I'm using Safari, and suddenly my Mac dies as if I had unplugged it from the wall. It automatically restarts, etc. Following is the crash report. Any suggestions? Thanks.

    The panic log indicates a fault in the drivers for the graphics processor (GPU.) Possible causes that have been reported include a failed GPU, overheating due to dust buildup or a failed cooling fan, and perhaps a bug that may be triggered by installing more than one NVIDIA graphics card in a 2009 Mac Pro and/or connecting more than one display.


    You can try booting in safe mode to rule out the system modifications you've installed as the cause, but I doubt it will make any difference.

    Thanks, but this problem occurs ONLY when I use Safari. Not Chrome, and not any of the many Adobe graphics programs I use daily.

  • Linc Davis Level 10 (192,897 points)

    Safari does not cause kernel panics. It may trigger a panic, but the underlying cause lies elsewhere.

  • galenfott Level 1 (0 points)

    As you predicted, a safe mode reboot didn't help.


    I appreciate and believe what you're saying about kernel panics, but if Safari is the only program on my Mac that causes a kernel panic, and there are plenty of other web browsers available, it's hard for me to view this as "not Safari's problem". Especially in the hopes that someone from Apple will see this post, and fix it.

  • Linc Davis Level 10 (192,897 points)

    No one from Apple is going to see your post and fix it. This is a known issue. If you want to read several hundred other reports of the same thing, see below:


    Diagnosing cause of kernel panic on a Mac Pro

  • galenfott Level 1 (0 points)

    Pardon my naivety.


    But that thread is indeed illuminating. My situation seems very like that of the user "myaka". As he concluded:


    "What worked: I eliminated use of Safari, switching to Chrome for browsing.  No KPs since."

  • ~Bee Level 7 (31,425 points)



    You may have a bad graphics card.  That would require taking it in.


    But before that, I would take a hard look at these three things:

    (are they up to date?  are they still necessary?  If not, you might consider deleting them to test as to whether they are possiblle culprits.

  • Linc Davis Level 10 (192,897 points)

    I guess I should state explicitly that since the same panic happened in safe mode, all third-party software has been ruled out definitively as the cause. There is no need to uninstall any such software.

  • ~Bee Level 7 (31,425 points)

    Ah, yes, I missed that info about safe mode.

    So at this point, I would take it in, galenfott.  Wish we had better news.

  • galenfott Level 1 (0 points)

    Thanks for all your help, guys. But given a choice between "taking it in" and "just using Chrome instead", I'm going to choose the latter! Too bad I can't use Apple software with my Apple hardware, but at least there are good alternatives. It would behoove Apple to figure out what's wrong.

  • Papa Snipes Level 1 (0 points)

    Sorry to hijack this discussion/thread.


    3 to 4 days ago, i've been experiencing very similar issues to the OP.


    Whenever i open safari, my macbook pro is unresponsive, very laggy, and not useable (It had got to the stage where i had to turn off my macbook, and turn back on).


    However, when safari is closed (it took about 45 mins to open and close the program), and i use chrome instead, my macbook pro runs much more smoothly.


    Does anyone have any info on what i can do to identify this problem? I'm not a tech wizkid here, so apologies if i dont understand any of the lingo!



  • Linc Davis Level 10 (192,897 points)

    Too bad I can't use Apple software with my Apple hardware


    Obviously, the reason why you can't is that the hardware is malfunctioning. If you don't want to fix it, that's fine, but your comment is a non-sequitur.

  • galenfott Level 1 (0 points)

    I disagree, but have no desire to argue with someone who's been as helpful to me as you have. I'll just apply the advice of Henny Youngman's doctor to the Safari/Chrome situation:


    Henny: Doctor, it hurts when I do THIS.

    Doctor: Don't DO that!


    Thanks again --

    Is there anything physically attached to your Mac?  Printer, Scanner, Hub, etc?
