iPhoto Faces and Contacts.app Trouble
Yosemite (clean install) and iPhoto (MAS) installed and are up-to-date.
iPhoto uses my previous iPhoto Library backed up from external drive (before clean install Yosemite I moved iPhoto Library to external drive, after installing Yosemite I moved iPhoto Library to "~/username/pictures/" folder and launched iPhoto with holding Option key and choosing my iPhoto Library as default).
Then, trying to add picture in Contacts.app I double-clicked photo-field and in pop-up window chose Faces section (which is not gray or absent as it was in some users reports after upgrading to Mountain Lion OS X. in my case the Faces section is normal and can be chosen).
Inspite of my iPhoto Library has a lot of recognized faces the Faces section in popup window of Contacts.app does not contain any of them just advising me to use iPhoto or Aperture apps to recognize faces.
Rebooting and reinstalling iPhoto.app did not help.
Any ideas?
