Hi,

I upgraded my iPhoto library from 08 to 09 after a restore. When I opened iPhoto, something went wrong when it began recognicing faces while also downloading my MobileMe galleries. I suspect something about the MobileMe sync failed and iPhoto crashed on me.

When I opened it again, it pretended to be done with facial recognition but it could barely recognize a face and I kept having to try to manually choose faces.

I decided to reset its face recognition feature so it would try again (this involves teaching all faces anew! Be careful).

  • Quit iPhoto
  • Go to your Pictures folder and locate iPhoto Library.
  • Ctrl+Click or Right click it and choose to reveal package contents.
  • Trash faces.db and faces_blob.db
  • Open iPhoto and wait

Also, Apple has a really good article on how to make iPhoto 09 recognize faces better: http://support.apple.com/kb/HT3442
