I tried to use DPP 3.0 on my Mac, but it could not display images?! I did show file names and types, but no image, regardless of if raw or jpeg (My raw files are Canon's .cr2). If I double clicked to edit, the program would crash. I tried to uninstall and reinstall it, but in vain. I finally uninstalled 3.0 and reinstalled DPP 2.2 and it works fine. I found only one post on the web with the same problem, but no one has posted a solution yet. Anyone here with the same experience?
