    Kernal panic - how common?
    Hi all,
    As the title says, just how common are kernal panics?
    OK, so my iMac aint that new:
    2007 2.8Ghz Core 2 duo 4GB ram running Snow Leopard 10.6.8

    Just had my first panic after 4 years. The curtain descended and I thought, what the heck is going on. The machine was doing absolutely nothing that I could see could warrant this panic. Having said that I do have a theory but as I know nothing about the reasons for these panics, I'll mention my theory later.

    I ran all the checks I know of:
    repair permissions
    verify disc
    Apple hardware test (full test)

    All these reported that everything was OK.

    Should I be concerned?

    You will get them every now and again, only if they become very frequent (like more than one a day) should you get concerned.

    1 panic in 4 years is a very good run

    Thanks for your interest in my post Louishen.

    Are you saying that a daily kernal panic is not unheard of?

    I sort of equate the kernal panic with Window's blue screen of death.

    You've done the same things I would, except also check hard drive SMART status in Disk Utility.

    My 2 cents. Here are what I consider 3 three levels of "annoyances on a Mac" (in decreasing order of occurrence):

    - slowdowns/spinning beachballs (98%)
    - program quits unexpectedly (1.9%)
    - kernel panics (<0.1%)

    The percentages aren't based on any sort of data...just my experiences/observations.

    Also remember that your computer should be running trouble free 99% of the the "annoyances" listed above would only be occurring 1% (or less) of the time...making the <0.1% for kernel panics be VERY infrequent.

    Basically kernel panics should almost never occur on a well running and well maintained computer. Here's a kernel panic article that's always a good read:

    I did as suggested and checked the SMART status.
    It says verified.
    Does that mean OK? Or do I have to run something to get the SMART status to update?

    My thanks to Pigoo3 for the link to resolving kernel panics.

    I will have a read and see what happens over time.

    Hopefully that will be the end of it.

    Verified means it is okay at the time of testing.
    Hang on to those original install discs like grim death! Using OS X.7 or later make a bootable USB thumb drive before running Installer!

    Kernel panics should be unheard of in normal use.

    I've heard of 'em but I've never seen one in 4-1/2 years of using OSX Leopard.
