so my fiancé purchased a MBP about 3-4 months ago and i believe is running leopard. I have a 4yr old Powerbook 1.5 G4. Can I take her OSX disk and install it on my pb so that I can have the same os? Im only have 512mb of ram, but am going to fry's electronics today and buying and upgrading that. I am just looking for something to hold me over until the Macbook's or mbp get refreshed, may even wait for snow leopard. Any advise would be greatly appreciated and sorry if this was posted in the wrong forum.
