Hey Guys So, my macbook pro just broke down. And all I'm left with is a Powerbook G4, that I borrowed. So I wanna upgrade the operating system on it but there are some things that I can't seem to figure out. Can I go directly from panther to Leopard ? My powerbook meets the req. Also, I have the install discs that came with my macbook pro. Any chance I can use them to install leopard on my Powerbook? When my powerbook is turned it just spits out the first CD ( which I think contain leopard) but what if I do a completely clean install? Will that change anything? Hope you can help.
