How come I can't connect my D40 to my Mac? It has a SD card in it, but I don't have a card reader, so I put in the SD card into the camera, and connect it to my PM G5. I don't have iPhoto or Aperture. Shouldn't it just mount on my desktop? It works fine on my PCs. The format of the SD card is NTFS I think. Also, it isn't in Disk Utility. The camera show's "Connecting to PC"
