Canon T2i and Macs

So you've taken photos on the Canon T2i and want to upload them onto a Mac computer. You plug the camera in and ... the camera does not appear on the desktop. What to do? Go to iPhoto, which will recognize the camera. According to Mike G. some other cameras do not appear on Mac desktops either so it's good to let people know to use iPhoto if the camera does not appear on the desktop.
