Kan ju vara bra att understryka :
Important: If you imported photos of people while using iPhoto 8.1, there’s an extra step you should take after installing the 8.1.1 update. Select all those photos, Control-click to open the contextual menu, and then choose Detect Missing Faces. This will redetect the faces in those photos and correct any face recognition issues introduced in iPhoto 8.1. You should not quit iPhoto during the Detect Missing Faces process.
