it would not work.
I may work if the backup was actually a clone of the other drive though.
Normally on a backup, the system files are not copied.
I have a powerbook with tiger on it and another powerbook with leopard on it. I have the leopard system backuped on an external hard drive. If I pluged the tiger into the external drive and copied it would the leopard system upgrade the tiger system? I hope that makes since...........
Thanks for any help
