imac won't boot after 10.2.8 update

Discussion in 'Apple' started by Allin Cottrell, Feb 25, 2004.

  1. I just applied the OS X 10.2.8 combo update to my wife's imac,
    which was at 10.2.4. The installation seemed to go OK. After
    the "Optimization" phase it asked for a restart and displayed a
    restart button, which I pressed.

    Now when I start the machine I get the gray apple screen for
    a couple of seconds, then a box saying "You need to restart
    your computer. Hold the power button for several seconds or
    press the Restart button". I did that of course, but now I
    can't get beyond that screen.

    So far I have tried booting from the orginal installation CD,
    selecting Disk Utility, Fist Aid, and Verify. Disk Utility
    says the HD looks OK. I have also tried booting with the
    Option key help down. This gives me an HD icon and a
    couple of buttons. When I press the right arrow button I
    get a "broken" gray apple screen (i.e. the gray apple with
    a nasty white random video overlay), and a hang.

    Help! Where do I go next.

  2. A bit more info, gleaned from attempting to boot in single-user
    mode. It's a kernel panic. I can't see the whole message,
    because the "You need to restart your computer" box is written
    on top of it, but here's some of the bad stuff:

    kld(): Undefined symbols:
    load_kmod(): kld_load_from_memory failed for kmod
    panic(cpu0) Unable to find driver...

    Could be a 3rd party kernel extension you had installed under 10.2.4
    that doesn't like 10.2.8.


    Holding the shift key on startup disables these extensions and lets you
    remove them if that's the problem.

    Another thing to check would be 3rd party RAM.

  4. Thanks. I wasn't aware of installing anything of that sort; and the
    Shift on start doesn't allow the boot to proceed.
    Hmm, it's all "out of box" imac hardware. Right now I'm trying
    re-installing Jaguar.
