I would like to put Lion on a MacBook (late 2006) currently running Tiger. Since it got a C2D CPU and 2GB RAM it should be okay. But I need some advice about the licence thing. Can I just buy Lion in the App Store on any Mac running Snow Leopard and put it on the MacBook in Target Mode? Or do I have to buy Leopard AND Snow Leopard for the MacBook too? Cheers.
