iPhoto 9.4.3 Won't Open
iPhoto 9.4.3 with Mountain Lion (10.8.5) will no longer open. I get the message "iPhoto cannot be opened because of a problem." I tried opening iPhoto from the Applications Folder, from the iPhoto Library, and from the backup Library on a separate hard drive, but I always get the same message. I reinstalled the iPhoto app from DVD and download but I still get the same message. Can anyone help? Thanks. Sonny6
