    I just got my first kernal panic. I read about what it is on the apple support site, but i wanted to know if any of you could tell me what the problem might be:

    EDIT: I just used Disk Utility to check my hard drives (both internal and external WD 500GN MyDisk) and it says both are ok with no issues

    There kernel panic corresponds to Safari but more specifically to "com.bluecoat.kext.bckd" which when searched for gives this thread. Or even a thread over at the bluecoat forums.

    Do you have Bluecoat installed?

    I would keep an eye on it for now and if it happens again try asking over there as I don't think many people here have heard of bluecoat let alone used it, Don't forget to report back though so we know.

    If bluecoat is not that vital to your work flow then you could always uninstall it.

    I do have bluecoat installed. But it isn't all that inmportant for me so I think I will uninstall it.

    When it happened i was in safari and i had was going to youtube. i typed the url in, hit enter, and i got the kernel panic. so i'm guessing it was going to block youtube, but the something went wrong.

    information about the bluecoat product i have can be found here:

    they have a new beta web protection kit for macs.

    thank you so much. i would never have figured out that it was bluecoat causing the problem.
