I have a black macbook 2,1 and a brand new macbook pro 5,3 with 2.8ghz will both of them support all of the new features in Snow Leopard i.e. Grand central and dumping some of the process on the gpu?
The Blackbook wont have Open CL support because of its intel graphics. But everything else and the Macbook Pro should have full support of Snow Leopard.
