Once upon a time it was Aperture. Because Adobe's Lightroom didn't have some things I wanted, I stubbornly stayed with Aperture including using "Retroactive": https://github.com/cormiertyshawn895/Retroactive https://github.com/cormiertyshawn895/Retroactive It stayed that until Apple eventually managed to bring Photos library up to the same spec including RAW support, non destructive edits, etc., and eventually even import Aperture libraries w/o loss. Since then, stayed with Photos, and it's BnL fine if you mostly ignore "folders" and let it do dates and people and now objects search on-device. To prevent errors, I've found I must maintain at least one machine where all originals are on a RAID array.
