So I had an aluminum 2008 unibody macbook. I replaced the hard drive with a 320gb and it has leopard on it. I damaged it and had to get a new mac. I now have a white unibody mac. To copy every thing would be a pain. I'd rather use snow leopard. What I want to know is if I can use the reinstallation disc 10.6 that came with the white macbook to upgrade my 320gb leopard hdd to snow leopard? Or will I have to go buy the actual snow leopard disc and waste $30?
