The genius bar said there is something I can to do fix my iPhoto library. It has been buggy and slow. I know it isn't the computer as I just bought a new 27 inch iMac yesterday. Sounded like the process was something like generating a new library or something from the originals? Does that make sense at all? I took my old computer in to do it with a genius after someone had suggested it there and the next genius wouldn't show me how to do it and said I need a new computer which I think was not true. But either way... I have a new one now and I would like it to work better. They only thing that I have brought over from the old computer is my photo library transferred via Thunderbolt.
