How to force a scan for People?
I just changed over my large family library to Photos.
As part of this I get the notice that I have 30000 photos, and XXX have already been scanned, Photos will scan for people "when you are not using the App"
Since I use an external that is not connected all the time I want to get this over with.
Does anyone know the exact procedure to use to get Photos to do this scan?
MacBook Air, macOS High Sierra (10.13.6), External Photos Drive
