    Hi so we have a computer at work that is receiving daily Kernel panics and it has not been very helpful in completing everyday tasks. At first I thought it was because of RAM that was installed but I ran the Apple Hardware Test and it didn't seem to find a problem. I have a copy of the log but have no idea how to read it. We are using a 2011 iMac running Lion 10.7.4, 3.4 GHz Intel Core i7. Any help would be appreciated. Thanks

    Is the RAM the original RAM or did you upgrade it yourself?
    If you upgraded the ram, try going back to the original ram.
    the hardware test isn't perfect.

    I had a similar problem with a Mac and it ended up being a RAM stick not properly seated. This is a machine that had the RAM upgraded at the apple store during purchase.

    When I opened the memory hatch is was very clear that one of the sticks wasn't properly seated. The memory in the machine is installed vertically (effectively hanging) so an improper seat will cause it to occasionally lose contact and panic.

    It is a quick thing to try yourself before hauling your machine to an Apple store.
