Apple care could not recover my iphoto library at all. All four options failed. Even going back into time machine and pulling a backup did not work. Had to manually build a new iphoto. I lost all my projects, calendars , slideshows, and books. Had to search all my jpg files to find my photos to create a new library, 8000 of them!! I am disgusted with the update and will not bring down a new one unless it is a patch to recover what is lost. Also, this one of the new update slowed both of my computers, imac and macbook. Thank God I did not update the macbook with the new iphoto.
