Sorry for advertising a competitor, but seems that Capture One resolved the migration from Aperture.
Capture One is a very fine raw editor, but insanely expensive in the last few years, so I give it up.
The free Fuji/Sony versions allows only import to catalogue, no direct editing from folders possible!

Except the extraordinary image quality provided by Capture One I like the very configurable tools menu!
