I have a macbook pro running Mountain Lion 10.8.2 and I have experienced frequent kernel panics. I wiped the hard drive clean and reinstalled Mountain Lion without any changes. After trouble shooting with the genius bar, the kernel panics are half as frequent but just as annoying. The KP's happen whether my MB is charging or not. The technicians said they couldn't recreate the KP at the apple store. I then remembered that the only time I havnen't had an issue was when I was visiting family during the holidays and only get the KP's at home. Could they be caused by a combination of Mountain Lion and my wifi? I use a time machine for my network and the internet can be spotty. The KP's tend to occur when I log onto Facebook, Ebay and when I use apps like Logic. Is there a way to eliminate this problem fully? Here's my crash report:

Thank you in adance or any advice.

    What's this:


    com.paceap.kext.pacesupport.snowleopard    5.7.2





  • ShanenahS Level 1 (0 points)

    I'm not sure. Do you think it could be the source of the problem? Thanks for replying.

  • clintonfrombirmingham Level 7 (30,000 points)

    Any non-Apple kexts are my first suspects for kernel panics. I'm not sure where this particular would be found - usually Apple kext files are in the root System>Library>Extensions by default, but you may have to use something such as the free "EasyFind" (from the App Store) to hunt this one down.


    When you find it, just move it to a folder on your Desktop and reboot. If no more kp's, then you'll know that's the problem. If further kp's, call back...



  • ShanenahS Level 1 (0 points)

    Hey Clinton,


    Apparently it's a PACE or propel excelerator. It's needed for my music recording software. I'll try deleting it an see if it helps. Do you see any other suspicious kexts?

  • clintonfrombirmingham Level 7 (30,000 points)

    Nope - I'm kind of suspicious, though, of the "snowleopard" tag - which is why I would remove it (at least for the moment). I would also check with the developer to see if maybe there's a new version of the kext that has Mountain Lion - instead of Snow Leopard - support.


    Good luck,

    You have the MacBookPro6,2, the Edsel of Macs. It may be covered by this program:

    MacBook Pro (15-inch, Mid 2010): Intermittent black screen or loss of video

    Make a "Genius" appointment at an Apple Store to have the machine tested. The routine hardware diagnostics used by service providers may not detect the fault. There is a specific test for this issue.

    Print the first page of the panic report and bring it with you.

    Back up all data on the internal drive(s) before you hand over your computer to anyone. If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you have at least two complete, independent backups, and you know how to restore to an empty drive from any of them.) Don’t erase the recovery partition, if present.

    *An SSD doesn't need to be zeroed.
