Hey there! I think I have a build for mac. Can't be sure though.
You can find it here https://github.com/Gleefre/waterdoor/actions/runs/3473009220 (as an artifact in the bottom of the page). You will need to unzip it twice.
Or you can find a once zipped file here: https://filebin.net/sj2b7ecmchb3zzg8 .
You will need an OpenGL 3 support probably, since I wasn't able (yet) to ship it.
Please, tell me if you are able to run it :)
