My friends got a white Macbook with 80gb HD, 1gb ram, 2.0 intel, runs tiger, 38GB free space on hard drive. So the problem is that i tried to install leopard on the computer, i followed the instructions for how to install, but it wont install, it says cannot install on this computer. This computer is fully capable of using leopard, plenty of HD space. And it the reason it gives for not installing is: Newer version of this software/program, already exists. I saved her photos on a DVD b/c thats all shes worried about keeping saved. So why wont this work and how can i fix it?? Thanks for any help, i tried finding answers already but couldnt find what i need.
