I'm sure this is a very dumb question... just bought my kids a Mac for Christmas. I installed the Canon EOS Utility software. When I open the software, I can select "Remote shooting" and make the camera's shutter snap when I hit the camera icon. However, I get an error saying "The application cannot be launched". Any idea if I need to download some other software? My end goal is to be able to do stop-motion movies. Thanks!
