Oh brother. I downloaded Sequoia 15.1 yesterday. This morning I opened Photos all set to remove some bits of dust from my B&W neg and..... NOTHING ! I clicked on Clean Up and almost immediately wanted to get rid of it. Apparently that's not possible. It would seem that Clean Up will rid your negs of unwanted people but not dust spots or errant scratches. And Red Eye--- what use is that to me? I'm strictly a B&W photographer. Photos editing has always given me exactly what I needed ---- until now. I can't believe Apple is so short-sighted.
I've downloaded a free app called Moravi. We'll see. And, I've sent a feedback email to Apple just in case a human might actually read it. I even talked to AppleCare to ask if it were possible to go back to Sonoma, where everything worked just the way it like it. Not really feasible without intercession at the Apple Store, yadda, yadda, yadda.
Bad Apple. Bad !
