Hi, i have a ibook g4 with the following specs. 1.07GHz G4 1.25 GB Ram CD ROM drive 30GB HD i attempted to install leopard with firewire through my mac mini, yet it get to the install menu and says: leopard cannot be installed on this machine. it is the two leopard discs that came with my mac mini intel c2d. I also have a powermac g3 i could run firewire out of if necessary. I dont know if it is the discs because i used the restore disc from a powermac g4 to upgrade this ibook to tiger. And help would be much appreciated.
