+1. I’m pretty sure Godot can compile for macOS but window APIs could be platform specific
they aren't platform specific, but compiling for macOS requires an Apple Developer Licence + SDK + XCode + an actual macOS install on actual Apple hardware. Meanwhile with windows + linux, you don't even need both systems - you can compile for either from either. It would only be fair for them to charge even more for the macOS version to make up all that cost.
