First off - I do not own any Apple products. But:
When I first saw this thread I was going to jump in and suggest Media Pro SE from Phase One. (Even Ken Rockwell uses it, so it must be good
) However yesterday (2018-08-30) Phase One announced that they will no longer sell Media Pro SE or offer any more updates. --- It's dead Jim.
Full disclosure - I bought the MS Expression suite which included Expression Media, which started out as iView MediaPro. MS sold Expression Media to Phase One who integrated some of the programs features into Capture One. Media Pro SE was a standalone Digital Asset Manager (DAM) - note I spelled out the definition so the moderators will not go ape over the use of the three letter word - hosting its own catalogue. I use it to categorize the JPEG's I have produced for distribution to the non-profits I shoot for and for my personal use. It loads images much faster off of disk and allows me to search for that already processed image quicker than going through my output folders.
