Hey ive got an alu iMac, and i wanted to re-install leopard on my emac 1.25ghz (will be 2gb ram soon after i realised its possible!) It currently has leopard on there but i want a fresh install before i sell it again.. it was 2nd hand and came with leopard in the first place My problem is im trying to use the osx install cd's that came with my alu imac.. i goto install on the emac (reboot from cd) and it says cannot install osx on this computer? anyone know why? Do i have a specific intel version of leopard?? it doesnt say anything like such on the cd and the utilities all run off the cd.. Ive never installed a mac os before maybe im doing something wrong? cheers!
