I'm thinking of dipping my toes in to the 1 series waters by purchasing a 1D classic from Adorama. I'm concerned on whether or not the camera will play nice with my Macs. I'm on the latest version of Leopard (10.5.8). No use getting the camera if I can't connect in order to make setting and user changes. Anyone out there using a 1D classic and a Mac running Leopard?
