How to add People in macOS Photos?

Initially there was a +-Button in the People-Album. add people

But at some point in time this button disappeared.

I can still CMDI a picture in my library and add a new person, but it for some reason does not give me the option anymore in the People-Album.

If I remember correctly I was able to look through a huge list of already identified faces and add a name to them.

Was this feature removed?

Solution 1:

You can follow this article on iMore to find out about how to add more people.

Although, my personal opinion is that this feature should've been more proactive and keep identifying in the background.
