I was transferring data from Time Machine backup to a 20"core duo iMac using Snow Leopard DVD when I aborted the process, I then got tthe above message. Tried to reset the PRAM, start in Safe mode, start in Target mode and various other methods without success. Still won't start. Snow Leopard is still inside the machine and refuses to come out. Need help.

iMac, Mac OS X (10.5.8)

Is it not possible to tell from the Panic message where the problem lies. I'm wondering if the DVD is stuck and this is the problem. I live in rural Ireland. Ireland is an expensive country + the iMac is 6 years old. If I thought it was the DVD I could find something on iFixit..

Sorry about the logistics and economics, but without the entire crash report, deciphering what you've posted isn't possible. As for a stuck disc, restart, holding down the mouse button. If that doesn't eject it, then run this command in the Terminal app:


drutil eject -drive internal

Thanks, but tried the mouse - no luck.

Can't get to Terminal.

Strange under normal startup it takes about 30 seconds before the Kernel screen appears but if I connect a USB drive and press Option by startup it can take up to 2 minutes and it looks like the computer is trying to access the DVD in the USB drive. But Apple in their wisdom say you cannot start from a lower OS than what is already on the machine. I have Snow Leopard OS on the machine, and the DVD stuck in the machine and only OS Leopard to try and start from. So maybe this is also a problem. Hope you can follow all that.

Not so. Apple says not to install an OS that's earlier than that which shipped with the machine. So, now the DVD's in an ext disc reader? If so, the mouse trick won't work. All I can suggest is try another computer or HD to boot the machine. Then, this Terminal one should work after you hook up the USB burner:


drutil eject -drive external
