    Installed the update, booted and wifi was not able to turn on.
    Rebooted, gray screen
    Rebooted 5x...finally got some terminal code, and then Apple screen of death
    Rebooted another 20x...finally got it to boot, installed 10.2.2 combo update I downloaded with a trusty PC
    Rebooted and worked great...for an hour. Then it froze, rebooted itself and wont go past the black gray screen...

    Guess the screen replacement and then the motherboard replacement just before the end of my apple care wasn't enough? They might have installed a booby trap at that time? Built in obsolesces?

    Waiting on a call back from Apple support. Pathetic when your focus is thin, and not quality updates.

    Totally dead since installing this update. Finally got into Internet Recovery, which forced me to install 10.8 or 7 I forget. Immediately updated to 10.2.2. Same issues as before, WIFI stopped working, iMac would grey screen, wont' even boot. Cannot get into AHT..
