Faces thumbnails missing after recovery from time machine
I got a new harddisk in my iMac via Apple's harddisk replacement program. I recovered all my data via a Time Machine backup (from a Time Capsule). All seemed fine after recovery of backup. When firing up iPhoto after the recovery iPhoto asks for updating all the thumbnails (don't know why). After a while everything seems fine - all photos are available with thumbnails in the events view. However all Faces thumbnails are missing - all persons in the faces view are black boxes. I can see that all the faces tagging are intact - when clicking a person I can see all the tagged images as black boxes. When switching the little "Faces - Photos" control to "Photos" I can see the photos containing all the tagged persons all right. I seems like it's only the face thumbnails that are missing.
So far I have tried the following without succes:
- Repaired the iPhoto database with iPhotos own tool (holding Command and Option down when starting iPhoto)
- Updating the entire library from an earlier backup
- Updated the faces database files from an earlier backup as explained in this post
I'm out of good ideas now - can anyone help?
