Deleting Unnamed circles

Removing automatically detected faces circles of people, we do not want to name, has only been possible in Photos 1 and Photos 2. In the more recent versions of Photos this feature has been removed. Apple did not say why. We can only guess. Probably the artificial intelligence algorithms need to know all people in the photos to recognise the type of scene, for example crowds at a concert.

We are no longer expected to name all faces. The album with all unnamed faces is gone as well and we just add the faces to to the people album that we want to name.

You can't

You can either show all face circles, or hide all face circles.
