Perhaps not the clearest title, but here we go. I recently got a Powerbook which came with Tiger. I also own a iBook running Jaguar. After using the Powerbook I came to like the OS and decided to pick up a copy for my iBook as well. When I received the DVDs they say "Powerbook G4 Install Disc" on them!! I thought I'd give the installation a shot anyway. No dice. As it turns out the eBay seller I bought this from is not returning any of my emails. Should I call it a day on this topic or is there a way to install this on my iBook?
