I have a macbook with leopard, how to switch to snow leopard?
Install it from a retail DVD. If you don't have one, phone the online Apple Store.
Check to make sure you can install Snow Leopard. In the upper left, click on the Apple and choose About This Mac. If the processor is a G4 or G5, you cannot install Snow Leopard. It requires an Intel CPU. Any G5 or earlier is a PowerPC CPU.
