    Hello All, I am having trouble installing Leopard over my 10.4 Tiger Mac,

    I am using "grey faced" dvd's that came with my 10.5 Leopard Macbook, to install Leopard on my Mac, but whenever it starts up the process of installing it, it gives me an error " Mac OS X can not be installed on this computer"

    It gives me 2 options, to restart or "ok", if i choose "OK" i can roam about in disk utility, password reset etc etc as you would"

    I am wondering if this is a computer/disk problem, or will I just need to go buy snow leopard from a retailer?

    Your Mac needs to have an Intel processor for Snow Leopard. Check "About this Mac" to make sure you don't have a G3/G4/G5 processor.

    If you do have an Intel processor, then I'd suggest you do a clean install. Back up your current HD (including the System Folder) to a cheap external HD drive and go from there.

    If you are trying to use a restore disk on a computer other than the one it came with, it won't work. It sounds like you are, because if it has a Leopard restore disk, there is no way you could have tiger on it.

    Restore disks don't work between different model Macs. You can buy Snow Leopard and install that on your Tiger Mac. Its only $30.
