I just upgraded my iMac today to OSX 10.8.2 from OSX 10.6.x and have had random crashes all day. It just happened to me for the 4th time in as many hours. Obviously, I can't go on like this. First time it happened was when I was messing with my Razer mouse settings just after the install of 10.8, and I thought there might be a conflict with the Razer drivers and the OSX mouse drivers. Second time I was simply browsing the internet and it crashed for no apparent reason. Third time I was loading a mission in Starcraft 2...it was not the game's fault, as after reboot, the mission was working fine. Fourth time was when I was browsing the internet again, using Firefox with no other apps open.


Here's the error report, can somebody help me please? This is very frustrating after just paying 20 bucks for an "upgrade" that rendered my computer extremely unstable.

    Most likely, one of these are the culprits.

    Boot into safe mode (restart holding down SHIFT key). If no KP, then disable these, reenable one at time to determine which. If KP, then most likely hardware related. Run the Apple Hardware Test suite, extended tests at least twice, followed by Rember.  See

  • MitchCarnes Level 1 Level 1 (0 points)

    OK, after a bit of googling to find out where my **** Library folder went, I was able to uninstall Sophos, which hopefully removed the com.sophos.kext.sav file, as I also read that could cause a KP. To be sure, though, I'd like to follow your advice.


    However, for some reason my iMac won't boot into any sort of discernable safe mode when holding down the shift key when booting. After holding shift for the entire boot process, it goes to my normal log-in screen at which point I log in, immediately hold down the shift key again, and it just boots as normal. No "safe mode" basic wallpaper, still my normal wallpaper and semingly all extensions loaded (i.e. the razer mouse driver still loads, etc.) This is pretty weird, I'm using a wireless keyboard, but I doubt that could be the culprit.


    Anyhow, if you can help with that obvious problem, I would appreciate it. Also, assuming I ever do get into safe mode how does one go about disabling those files? Is there an options panel or do I have to find them in Finder (which seems to hide all the important stuff anyway) and manually delete?


    Thanks a lot for your help.



  • Barney-15E Level 8 Level 8 (43,155 points)

    If you have a wireless keyboard, press the shift key immediately after hearing the tone, or use a wired keyboard.


    OK, after a bit of googling to find out where my **** Library folder went, I was able to uninstall Sophos


    Was the uninstaller buried in there somewhere, or did you just remove stuff that said "sophos."

    If you did the latter, it might not have been uninstalled.


    You disable them by uninstalling the software that installed them using the uninstaller that came with the software.

  • MitchCarnes Level 1 Level 1 (0 points)

    Thanks for the reply, Barney.


    I'm actually no longer by my computer (replying from my gf's house). I held down shift for the entirety of the boot process to no avail. I'll try it again tomorrow. Unfortunately, I don't own a wired keyboard, so if that's messing things up for a safe reboot I may be SOL.


    The Sophos uninstaller was buried somewhere in the main iMac>Library hierarchy (I can't remember which folder exactly, but as soon as I saw "Sophos uninstaller" I ran it...then it proceeded to "install" the uninstaller, after which point I couldn't find it again. So, hopefully, it's gone along with associated drivers, etc.).


    The problem with running uninstallers, at least with my limited eight or so hours of experience in 10.8.x, is that they can be quite difficult to locate if they're on a system level and not a user level. I only happened to see that Sophos uninstaller randomly in the Library>LaunchAgent or Library>Startup Items (like I said, can't remember where exactly I saw it) folder afer googling how to even see said folders in the first place. Doing a spotlight search for "Sophos" or "Kext" yielded zero results, as did running a spotlight search for the specific files "om.sophos.kext.sav" or "com.razer.common.razerhid" that Baltwo suspects are the culprit. I even did a search for Razer with no results. Unless I'm missing an option to show hidden files in the spotlight search, I'm afraid I might never be able to even find those files once I get safe mode, hopefully, working.

    Have you checked Safari > Extensions for Razer?

    Or, in your HD > Applications > Utilities Folder ?  Is there a Razer folder there?  Look inside to see if there is an uninstaller there.

  • Barney-15E Level 8 Level 8 (43,155 points)

    That's why you should never go installing stuff without completely understanding how to uninstall it.

    Sometimes the uninstaller is on the dmg that the software was distributed on, sometimes it is part of the installer package, and sometimes, the developers will put the uninstaller in a folder on the hard drive. And, you may have to just go to the website and download one (or the instructions on where to find the stuff to delete).


    Just deleting those kexts will likely cause other problems as the software that wants it to run will be attempting to find the file and activate it. The kext might not exist in a findable place. It could be inside another file package.


    To find Hidden and System files, select Other from the Criteria popup menu. Then, go through the list and find System Files and Visibility and check the boxes next to them to keep them in the menu.

    Then, add those options to the Search Criteria.

    Screen Shot 2013-02-27 at 6.03.02 AM.png

    Then, wherever you start from, it will search down into that hierarchy for files that match that additional criteria.


    Googling for it, Razer seems to be a mouse driver.

  • MitchCarnes Level 1 Level 1 (0 points)

    Yeah, Razer is a mouse driver, this is the one I installed intentionally adn wanted desperately to keep on my system. I have big hands and it's an accurate and very adjustable mouse. The Sophos antivirus, though, I have no idea how that got on my computer. It could've been a remnant from when I migrated my data from my mom's Macbook Pro from a few years ago onto this iMac. In any case, uninstalling Sophos seems to have done the trick, I haven't had a kernel panic in a couple days now whereas I was getting one every couple hours before. So, I think I'm in the clear


    THanks so much for your help everyone!


    - MItch

  • Barney-15E Level 8 Level 8 (43,155 points)

    If Sophos was that old, it probably was not compatible.

    Those things have to dig in so deep that almost any changes to the OS make them break.
