I have given the photographer another powerbook with the same specs. It has a fresh OS load. We have tried different card readers, different cards, different cards with pictures from different cameras. I have used 4.4.3.1 and 4.5.2 and both versions still have the problem from my previous post. There is nothing in the console log pertaining to Photo Mechanic. The only weird thing I noticed was that the last few lines said "Could not find application for bundle ID: com.apple.iPhoto". I photo has never been installed on this system. I noticed in the forums you have a debug build of Photo Mechanic. Maybe that might gather some more information to diagnose the problems?
