I have a theory this may be an issue of permissions on Mac, an issue I haven't figured out how to solve.
Someone on another forum told me this, which i've been told before.
----------
macOS app is missing the execute flag on the binary:
Bash: chmod a+x "OurApartment.OSX.app/Contents/MacOS/Our Apartment"
---------
I do not know how to solve this making builds on windows, but I may work it out in the future.
