I try yo play the game on macOS and everything is black... except the rain drops on a glass (which probably is self-emitted as a particle fx). There is no lights in the scene. I am using the latest MacBook pro with an AMD Radeon R9 M370X 2048 MB graphic card, so I don't think it's my hardware's problem. Have you tested the macOS build in any macOS device? Also to run the game I had to chmod +x the executable inside the app/Content/MacOS folder, which it's name is x86. Is this a x86 mac OS build? It should be a Universal or x86_64. I don't think that apple support x86 mac devices.
