10.4.6 has blocked my iMac

I installed the 10.4.6 upgrade package to my 10.4.5 iMac and rebooted as instructed.

Now i have the very first screen (white with apple logo) and the turning timer cursor. Does not move further.

I tried feeding the iMac my old Tiger install disk to re-install but I never get further than the white apple logo screen.

Does anyone have advice on how to wake up my iMac?

thanks
 
At first a few minutes, now on the last attempt it left it for over 15 minutes. Actually if I listen carefully I can hear the harddrive work away for about 5 mins then silence.

In between, and still with no success, I have reset PROMs using open-firmware.
 
back again, I have activated my iMac in target disk mode and I can access all files, which I am recovering really fast....

So the issue really is, how do I get the iMac to accept a full install from scratch.
 
Install the 10.4.6 update via FireWire Target Disk mode -- and this time, let the computer sit.

The 10.4.6 update, upon first reboot, takes significantly longer to boot up, and should not be interrupted, since critical update procedures are being run. More than likely, your computer was not "hung" or "locked up" -- you simply did not wait long enough. Mine took 10 minutes or longer to complete -- it's not out of the question that yours would take longer or shorter.
 
I eventually re-installed Tiger from scratch and the full 10.4.6 combo. Actually I was quite impressed I could re-install the OSX and maintain all my personal files.

With respect to the reboot, point taken, I should have waited longer, but how long is long? In my case I did non interrupt the reboot before the hard disk had stopped churning away for some time...

Maybe apple should consider presenting a screen indicating that something IS actually happening.
 
Interesting. I fully expected to have to wait while it updated my G4 2x1GHz tower 2 days ago but the 10.4.6 update ran very quickly and caused no glitches whatsoever (touching wood!) I did "Repair Permissions" before and after" (and was surprised to find no permissions to repair afterwards - none at all!)
 
Yes this upgrade was a little different from what we're used to. The "second reboot" while it was booting up was rather weird, but this is normal during the 10.4.6 update according to Apple. I didn't notice that it took very long on my iMac, but usually during the updates I'm doing something else to keep myself busy from touching the Mac and possibly causing more harm, which is what I believe happened here (no offense ;)).

The other factor in my quick update could be because I have an iMac G5, but people who have G4 Macs and lower have said that the update has taken considerable amounts of time.
