OK, new convert here - just bought an iMac, PC is in the trash! With windows, I would plug my Olympus C5050 into the usb slot, and the transfer of images would immediatly start. With my imac, I plug the usb cable into the camera, and absolutly nothing happens. Any thoughts on how to get me on the right path? Do I need to download drivers from olympus? I thought mac had a feature similar to plug n play No? thanks.
