As far as I know, native Blender SDF modeling tools are not in sight at the moment.
ConjureSDF might eventually follow for macOS, but looking at the developer’s progress, that might be far into the future (no offense, he’s probably very busy).
Womp is pretty nice. It would be the number one option for me if I decide to go back to Mac. I would go for the paid version then.
Clavicula has lots of potential, but the releases are very irregular. I’ve fooled around with it, but I don’t dare to really invest time in it.
All in all, MagicaCSG is really ahead of the SDF pack at the moment, and that might get a macOS version in the future, but like ConjureSDF, that might take a long time.
Don’t get your hopes up high in that respect. Check the “SDF in Blender” section of this post to read everything I know about it.
