May I suggest RawTherapee?
Darktable in my opinion has very poor noise reduction algorithms. The best of them makes the picture very painting-like if taken using a high ISO level.
RawTherapee removes the most annoying chroma noise entirely when the noise reduction is turned on, and the amount of reduced luma noise can be adjusted. No painting-like appearance.
See How to reproduce camera noise reduction using open source software? for some noise reduction results. There you can compare the RawTherapee pictures with darktable pictures. Be sure to click the pictures to get maximum possible size.
The only caveat with RawTherapee is that the GIMP plugin doesn't work on Windows 10, the newest version of GIMP and the newest version of RawTherapee as of the time I'm writing this, so you'll need to remove the plug-in. This problem probably doesn't apply to MacOS.
