I'm not able to export photos from my Canon camera to my iMac since I upgraded to Yosemite 10.10.3. The thumbprints appear, but a message comes up saying the photo files are unrecognizable and cannot be exported. Seems to be a software problem--I'd just been successful a few days before, with 10.10.2, before I upgraded. I don't know if there are any solutions other than buying a camera that is compatible or ditching the computer!
