macos - MacBook Pro 3,1 Snow Leopard Installation


I have an MBP 3,1 (Mid-late 2007 model) and I'm trying to reinstall Snow Leopard. I don't have the original discs with my Mac, I got an original Snow Leopard install disc from another MacBook Pro but when I try to install says "Mac OS X cannot be installed on this computer".


Is there any way to re-install Snow Leopard on my machine?


Answer



The discs that come with a Mac are custom to that model (at least they used to be). If the other MBP isn't a 3,1 model then the install can fail like you experienced.


If the two machines are the same model, it might be that the other discs are upgrade only, and require an existing OS X installation before the upgrade can proceed (I had this problem with a MacBook that came with Tiger DVDs and Leopard upgrade DVDs as Leopard was just out - you had to install Tiger first, then upgrade to Leopard).
