Resolved Cannot install Snow Leopard on 2008 Mac Pro

[RangerNed]

I've tried 2 different OSX 6.3 DVDs but still get the "Mac OS X can't be installed on this computer" message. It has 32GB of RAM, so that's not the problem.

Are you using the Retail DVD/Mac Box Set or Recovery Discs? Have you also tried creating a Snow Leopard USB installer?

I was using a recovery disc for a MBP, but the retail disc I found in my loft works now. Thanks.

Turns out Apple locks Macbook copies to Macbooks.
