Hi Steve and welcome here! How exactly do you transfer the photos? The camera says "transferring photos" but it just mean that the camera is connected in the file transfer mode. In other words, the photos are not transferred automatically! You just have to open the Finder (or any other file manager you use) and simply drag & drop the images from Ricoh drive to your Mac drive. Hope this helps? If not, don't hesitate to ask for further assistance.
