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)
  • Linc Davis Level 10 (184,680 points)

    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.

    Thanks Linc for your pointers!


    The problem is indeed recurrent. And it happens often when the computer is doing "nothing": last Sunday, I started a manual backup of my files, as I do every week, and went away for some shopping. A couple of hours later, I came back and found out a window opened on the iMac telling me that the computer restarted because of a (kernel panic). It was just copying files, with only the Finder running!


    My hard drive was changed twice in a two-weeks period a few weeks back and I discovered recently that my iMac was under the recall program for faulty hard drives. Since the drive was changed twice, I surmise the iMac's hard drive doesn't need to be replaced.


    I thought the problem was with my HP printer (I had some major problems with it in the past) and unplug it. Right now, I have external speakers plugged on the headphone jack and 3 USB devices: an Apple keyboard, a USB cable for my iPhone/iPad and a USB 3 cable I use for my G-Drive Slim external hard drive. That may be the cause of the bugs, so I'll try to disconnect the cable for a few days and see what will happen.


    And to make matters worst, my Time Capsule is behaving badly since the panics, telling me that "Time Machine couldn't complete the backup to the Time Capsule because the backup disk image '/Volumes/Time Capsule/Rémy.sparsebundle' is already in use." It may be unrelated, but the message occured not long after a kernel panic…


    I installed OS X a couple of times in the past weeks, following the hard drive incidents, settling on 10.7 and trying my luck with 10.8 afterwards. So far, with the panics and the periodic "crashing-for-no-reason" occurences on Apple applications (Safari quitting without saying a thing, iTunes connecting to the iTunes Store and quitting just like that, etc.), Mountain Lion is a big disappointement to me, enough to consider throwing away some of the features I was using to go back to Lion.


    I… just… don't know what to do.

  • Linc Davis Level 10 (184,680 points)

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

  • woodmeister50 Level 5 (4,850 points)

    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.

  • a brody Level 9 (65,390 points)

    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 a AHT, but to no avail. I've held the D key for almost two minutes… and the Apple logo popped on. I've tried to run it from a Snow Leopard Install DVD and the iMac restarted immediately instead.


    In the meantime, I've disconnected everything connected to the Mac (even the iPod cable), leaving only the Apple USB Keyboard connected and let the copmputer run by itself for a day. When I came back, I had a window telling me the "computer restarted because of a problem".


    Without the ability to run a AHT myself, and considering that connected peripherals may not be the problem, the other possible culprit could be faulty RAM, as Linc suggested. Although my 16 GB of RAM installed are not the ones that cam with my iMac when I bought it, I never had problems with them before. And reverting from 16 GB to the default 4 GB I had is a bit… well, frightening.


    This said, I remember that the Genius who took my iMac for repair the second time the hard drive was replaced was suspecting a problem with the logic board.


    So, it seems my only solution would be, apart from lobotomizing my iMac, would be to contact AppleCare or my local Genius Bar and return the iMac (for a third time in 2 months) for inspection and repair…


    Do you think that those recurring problems would be enough to demand a full computer replacement?

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