so i got a used macbook for christmas, and it has leopard installed. The macbook didn't come with the install disk for leopard. My problem is that i want to put in a new, bigger hard drive, but to do so i need install disks for OSX, that i don't have. I do however have the OSX installation disks that came with a macbook pro. Can i use them to install OSX on the new hard drive? I wouldn't think that using them would work on my macbook, but i thought i would ask anyway. My other question if the macbook pro disks won't work is how should i go about getting a copy of leopard? i would assume that i have the right to use it if i purchased a macbook that had it already installed on the macbook, but i don't want to buy a copy if i already have a license to use it. thanks in advanced.
