Is there a way to permanently remove a name from the faces in the new Photos app?
Example:
When you tag a face accidentally with "John" instead of "John Miller", you can delete the face associated with "John" and remove the "John" tag from all your photos, but "John" will still be suggested every time you tag a face and start with "J…".
I guess this is especially annoying when you type fast and tag a lot of faces, where you will end up with dozens of typo/etc. names that will be suggested to you every time you enter a name…
Best Answer
The iOS 12 and macOS 10.14 versions of Photos makes this significantly easier.
Select the face / person / name in question and then select:
That purges the name and face from ones it will select in the People Album. I do see that both platforms will find names from your contacts, so if you just removed "Mary" from your album and you have any contacts with Mary in them, you will still get prompted. Temporarily deleting the contacts (make a backup) or deleting the sync of cloud contacts like iCloud and Outlook.com (or the many other contact sync options) you can test that Photos doesn't have that name anymore to suggest to you.
