Thanks, Soosie_J215.
Yes, I use all those those steps. I estimate that, more than half the times, they are problematic. Very often, when I click on the 'name' field, the field disappears; only after numerous attempts does it stay put so that I can type in a name. Also, frequently, I can't move the circle to anywhere near the face (especially after I crop the photo; it seems that the circle wants to stay where it was before cropping). And after (sometimes minutes, sometimes days) I input the name and move on to another photo, the name disappears; I've input the names into the same photos many times. I'm never confident that any names I input will remain there. Aggravating!
In the People album, I have 1375 faces identified. They are supposed to be in alphabetical order; but a few are not and I can't see why. Also, more than half of the boxes have no photos; they have just the people's names. When I close and open the album, including after being closed overnight, a different number of boxes, though hundreds, have no photos. Right now, ALL boxes have no photos! Yet, a few minutes ago, for a few seconds, all photos were shown.
Remember this is happening on my M2 MBAir (with 8GB memory) and running Ventura 13.4.1. I'm afraid to upgrade to the next OS for fear of having to start again to rename oft-renamed face names. Thousands of name fields are blank, despite having re-input the names of many of them numerous times. I've never managed to re-input all of the names, because while I'm doing that, ones I have just re-input have again disappeared.
Thanks for any help you can provide. I will likely buy Mylio which, though simple, is way beyond my simple needs. iPhotos and Photos have always been a drag for me this way. Nice idea poorly executed.
