Hi guys, i really need your help here. My friends 12" powerbook was sent in for repair. He got a new case because his old one was really messed up. Anyways they sent him back a computer with what seems to be an empty hd. When I turn it on, a little icon with a question mark comes up. He lost his original osx cd's, so i took the powerbook home and inserted my tiger cd's (wich i got with my 15 inch powerbook) and it boots from the cd then tells me that it cannot install the software on this computer!? Is this normal, i thought you could install tiger on any number of computers. I need to get osx running on this laptop. What do i have to do!?
