since the last update I have found that iPhoto crashes on my Mac mini. It doesn't on my Macbook Pro nor my Macbook Air. It was also showing a lot of pictures distorted. After searching on the internet I decided to restore an old copy of the application from my time machine. However in the process it stopped when I selected 'replace existing copy' and said that I should check the application info and ensure that all items that I was restoring were unlocked. Since it was only the iPhoto application I checked that and it was 'not locked' I then tried restoring the old copy and leaving the existing one there but after doing so both copies crashed on startup. I have now deleted both copies and reinstalled iPhoto from iLife 11. The application updated OK with the latest update but it still crashes on startup. Does anyone have any advice on what to do now?
