I'm working with Canon 20D camera and just got a new Mac Mini with Leopard (Mac OS X 10,5). In this case, I've had no difficulty in transferring pictures and working with them with Photoshop CS3. I have, however, installed several updates to software since starting out. Both Apple and Adobe seem really committed to resolving these issues as quickly as possible and I would advise logging on to get the updates for both before trying to work with anything. They seem to be issuing updates on a daily basis, so far, so somebody must be having some issues. Not me, I'm happy to say. The only problems I have run into are getting scanner and printer driver updates that work with the Intel-based Mini. While that surprises me, it doesn't surprise me much. Everything works fine on my Power-PC based laptop.
However, Nikon and Mac people will need to address those specifics.
