    I've recently downgraded from snow leopard down to leopard using from a time machine backup. Now when ever I boot up it with a kernel panic, I've tried multiple restarts and it still shows the same thing.

    Can anyone help?

    How far do you get in the boot process? Does it even boot before the Kernel Panic occurs?

    Did you try starting up while holding down the shift key or Command-V?

    I hear the chime then see the apple logo for about 5 seconds then the kernel panic comes up.

    I think that what you are doing is not officially supported by Apple, especially when restoring from a Time Machine back up. Do you still have the TM backup on an external hard drive? If so would it be worth reinstalling Leopard on a freshly formatted hard drive in you iMac and then only copying over key files that you need. I know this defeats the point of a full backup, but this should get rid of the majority of problems.

    What do the last few lines of text say? Also are you restoring to Leopard from a Snow Leopard Time Machine Backup? If you are I don't think that will work.

    I've never heard of that message before. Are you downgrading using a Time Machine Backup that was made using Snow Leopard?

    I'm just going to install from a fresh copy of leopard no restoring from back up.

    Well then Leopard won't like that. If you can you need to restore from a Time Machine backup that you had before you installed SL. If you don't have one that old then you have to start from scratch. I think there are some programmes that can get individual files from Time Machine backups.
