Keep in mind that even if you keep Aperture running, you can’t use newer cameras. Apple stopped updating raw support.I have more than 100000 picture in Aperture many edited and all in specific albums, I do not want to loose all my legacy work. Also Capture One Pro costs at least 350, that’s a lot of money for me. I do hope one day Apple brings Photos up to spec with Aperture and then I can move.
