Hey all, I am trying to install Mac OS X Leopard onto my iBook G4 Mac OS X 10.4 Tiger. Every time I try to install, it takes me to the select the language, okay, then it says "Mac OS X cannot be installed on the computer". I performed the installation exactly the way it should be done. I have the latest Firmware which was the only option I found to check if something like this happens. I have tried everything on the Troubleshooting webpage except the erase install, which I what I would like to do next, but I do not know how to do this. Could someone please help me? I need help on why my Mac is doing this, or how to perform an erase install. Thanks so much.
