Regarding the comment of, > Unluckily I cant switch to Leopard - having a G4. Isn't Leopard 10.5.x? If so, that runs nicely on G4's. It's snow leopard that is 10.6. (Why does Apple use confusing names instead of simple numbers, and what do they do after Ocelot? Is there another big cat for 10.8, or do they switch to small cats?)
