Since I upgraded to ML a couple of months ago, I got several kernel panics… It cost me a new hard drive a few weeks back (well, it was under AppleCare, but I had to change it anyways) and now the kernel panics occured almost once or twice a week.


The latest one was today: I was listening to music on iTunes and I decided to check something on Safari. With Safari opened, I opened the System Preferences and the song playing on iTunes started to hiccup and my iMac restarted itself.


Here's the report I had upon restarting:

Since I don't know jack about all this technobabble, can someone please tell me what's causing my kernels?


If I wanted this kind of crashing and upheavals, I would have bought a PC…

iMac (27-inch Mid 2010), OS X Mountain Lion (10.8.2)

    That panic was not caused by third-party software. If the problem is recurrent, the possibilities are (1) a damaged OS X installation; (2) a fault in a peripheral device, if any; (3) an internal hardware fault; and (4) an obscure bug in OS X.


    You can rule out the first two possibilities by reinstalling the OS and testing with non-essential peripherals disconnected. Probably there will be no change. In that case, make a "Genius" appointment at an Apple Store to have the machine tested. You may have to leave it there for several days. There isn't much point in doing this unless you can reproduce the panic, or unless it happens often enough that it's likely to be repeated at the store. Otherwise you may be told that nothing is wrong.


    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 know how to restore, and you have at least  two independent backups.) Don’t erase the recovery partition, if present.


    *An SSD doesn't need to be zeroed.

    If the hard drive was replaced twice, you probably have bad RAM or a bad logic board.

    Before making a trip to the Apple store, run the Apple

    hardware test, with only keyboard, mouse, and monitor



    Follow the instructions here:


    See if there is a hardware fault causing the issue.  If the

    results say the hardware is okay, then it is an OSX or

    driver issue.

    Often the underlying process is the problem.  Tablet finder. Make sure your tablet drivers are designed for your operating system.  Mac OS X 10.7 and above does NOT mean it is 10.8 compatible.  It only means it is 10.7 and 10.7.1 compatible, and may be 10.7.2 through  10.7.5 compatible, and with luck is 10.8 and later.

    I've tried to run it from a Snow Leopard Install DVD and the iMac restarted immediately instead.

    AHT is on the Apps Install disc, not the OS install disc.
