I did not want to hijack the other gentleman's thread so I decided to post my own. I tried connecting the camera via USB to my MacBook Pro, and then turning it on. But Canon Utility never launches. This is a version that came with my 5D; do I need another version for the 1Ds? I then manually launched Canon Utility, but all of the options except "Monitor Folder" are grayed out, it won't let me select "Remote Shooting."
