    Leopard requires an 867 MHz or faster processor. There are ways to get it installed on your Mac. You can Google for that. If you are trying to use the Install disc that came with your macBook, that won't work. You'll need a retail copy of Leopard.

    i have bought a tiger install disc from ebay this is a silver disc not a black one with the big X on it i have tried to install this too and it starts as all is well but after language selection it just reboots back into jag,
    my g4 runs all software that ive tried to install on it do you think it might be a hardware problem or just that im trying to install the wrong operating system software??

    Probably need a new install disc

    I think the biggest issue is that the DVD you have for your MacBook is probably only the intel native version of OS X. Without PowerPC code, it'll never boot. Buy/acquire a PowerPC version of 10.5.

    Next, that machine is officially unsupported by 10.5, which means you'll have to trick the system into letting you install onto it. Answers on this can be found here:

    Edit:
    Tiger should work unless the disc came from Tiger that was meant to be installed on a first generation intel iMac, MacBook, MacBook Pro, etc. Does the CD say anything like "for installation on ______ system"? Or does it look like a genuine retail copy of 10.4?

    Try to use disk utility (from the Tiger DvD) to format the HDD first! :cool:
