    My son was watching netflix when the entire computer froze (beach ball with no resolution)

    I couldn't force quit safari, or soft reset so I held power for a hard reset.

    Upon rebooting, I got the grey screen with the following text;


    panic(cpu - caller 0x55bfa5): "Unable to find driver for thsi platform: / "ACPI/".\n"@\SourceCache/xnu/xnu-1504.9.17/iokit/kernel/IOPlatformExpert.cpp:1389

    (that's across the top on a single line), then it mentions:

    Debugger called: <panic>
    BSD Process name corresponding to current thread: nknown
    Mac OS Version:
    Not Yet Set
    Kernel Version
    Darwin Kernel V10.5.0 and then it displayed a date that was inaccurate by two and a half years.

    My guess is hard drive becuase it was starting to feel chuggy, but that's just a hunch. Also, I've had hard drives fail on me before and what happens on start up is typically different (A sad face with a disc drive icon or something if I remember right)

    Anyways, any thoughts on what's up?

    Do you have anything else that you can boot off of to test... OSX disc, or whatever?

    Have you tried a Safe Boot first? Link here for Apple support doc re: how to do and what it does.

    Sometimes if you do this (it takes a while to boot up this way), and then shut down normally, everything will resolve and bootup will return to normal.

    No, I haven't done any real troubleshooting yet. Didn't have time. Was saving it for either tonight, or on the weekend.

    So far from what I've gathered, I'm going to try to boot into safe mode then shut down and restart.

    If no go, then try to boot off the cd (if I can find it. Fingers crossed.....) then if I can't access anything, I'll attempt to wipe the HD and re-install.

    If that doesn't work then I'm stumped up to this point! ;)
