so my Intel iMac suddenly decided it no longer wants to play nice with any of the digital camera's in the house. iPhoto, Aperture, image capture... nothing. It says the files are unreadable/damaged. Umm.... the cameras work fine on the MacBook Pro and PBG4. (Canon 10D and Powershot SD300) I was going to call AppleCare but its a sunday and I need the camera dumped to the iMac TONIGHT! Help?
