macCuller is for the first pass through a folder of photos. You open the folder, look at each photo once and press a key: K to keep it, G for maybe, D to reject it. It moves straight on to the next photo. When a whole burst is obviously wrong, switch to the grid and mark many at once. At the end, Move sorts the files into _keep, _maybe and _reject folders next to the originals. macCuller never deletes anything. Rejected photos wait in _reject until you decide to delete them yourself.

Your marks are saved inside the folder as you go, so you can quit at any point and pick up where you left off. Every mark shows a symbol (✓, ?, ✕) as well as a color, so you can tell them apart without relying on red and green. macCuller is currently in TestFlight beta.
