After the firmware update, my iMac doesn't start. Sometimes it hangs up on the starting progress bar, or it takes me to my blank desktop. Please help! It drives me nuts!

iMac Intel, Mac OS X (10.4.6)

    Did your iMac successfully complete the firmware update, and then malfunction, or do you believe that the update was unsuccessful? Which firmware update are you referring to (Firmware update 1.0.1 or the SMC Firmware update)? If the former, you may have to restore the original firmware and try over again. Did you make a copy of the firmware restoration disk as was suggested? If not, you may need to do so using another computer, restore the original firmware, and try the process again.

    I belive I update firmware succefuly. After the restart I heard the fan went really loud for seconds. Then iMac asked to restart again. From that time my iMac doesn't start... Since I can still safe boot the computer, I guess I will create restore CD.

    A silly question, what is exactly the safe boot?? I can check my email or browse website but I can't print...

    Zap your PRAM. Boot holding down the Command, Option, P and R keys until you hear two chimes.

    Thanks for the suggestion of zapping. Still froze on the starting up....

    I created the Firmware Restoration CD and followed the instruction. It didn't work... still stuck in the start progress bar.

    According to the instruction, press the power button and wait for the 3 fast, 3 slow and 3 fast blinkings, but my iMac did really fast blinks more than 3 times and beeped. But I inserted the Restoration CD anyway. and stuck...

    Maybe it doesn't restore if I have SMC Firmware already?

    I hope my iMac will be healthy some day even I restart & shutdown million times...

    Please HELP!

    Try resetting the System Management Controller:

    Still hangs up on the starting progress bar.

    I could force quit, restart and shutdown by the keyboard/button (safe boot situation). Unplugged the power cord still my iMac is f_ed up.

    I'm thinking...hmmm.

    At this point I would take in for repair, it is after all still under warranty.

    I talked with the iMac tech support and solve the problem. Basically I had to archive and install. It runs great now. Thanks for the help, all of you guys!!

    I am experiencing the same problem as described.

    While archived install will correct the problem, the issue is not solved.

    After experiencing the same issue, I did an archive install in order to backup my work. I then proceded to do a clean install of the whole system and restoring my backup.
    I then updated the system with the latest patches.

    After the update, I am having the same problem again. My machine boots into a blue freezing desktop with nothing.
    Safe mode works. I can choose to do archive install again, but I am not a huge fan of having to do everything again.

    I hope Applecare won`t tell me to do an archive install.

    I'm assuming you have zapped your PRAM and reset your SMU. Boot up in mode and:

    Go to system system preferences/ accounts/ login items - and clear everything.

    Open Finder from your dock > HD > library > startupitems
    move all items to trash and empty. Any PPC items of course.

    Uninstall that pesky Adobe Version Cue if that's laying around.

    Restart.

    Yes. It seems like it was Adobe Cue that caused the problem.
    A few hours wasted is all, everything works smooth.
