Had an issue last night where we were trying to download some pics from a friend's camera that he had plugged into our imac after logging onto the 'guest' account - which we have never used before. The Mac just kept on waiting and waiting and for the first time ever I had to do a Force Quit to get it to stop. When I logged on to my account it all worked perfectly. The obvious question is ---- why?
Have parental controls been added that stops pics from being downloaded, or some other filter on the guest account?
