In order for me to properly use my memory card reader via USB port I need to find it's icon somewhere. I can't find the damn thing! Can anyone tell me where and or how to find the card reader on my IMAC so I can D/L movies? When I plug in the card my images will D/L automatically to IPHOTO but I know there is other data on that card but can;'t access it. I assume I must find the icon so I can "control" the reader. THANKS!
