Jane, There are certain cameras that will work on the Mac and certain ones that won't. Most depends on which OS you want. MacOSX supports almost anything you throw at it but you have to check on the side of the camera box. If it says "MacOS Compatible" it's good. Some cameras will even go as far as to put the "Built for MacOSX" Logo on the side of their box.As far as I know almost all canon digital cameras are Mac enabled. I have one myself and it works great. CJ
