PM TTYD - OSX:
Paper mario requires an emulation feature called "bounding box". But this requires an OpenGL 4.3 feature released in 2012. Bad luck, Apple did abandon their OpenGL driver a few years ago [1], so it seems unlikely that they will ever support it. So if you don't want to get Apple to support OpenGL or Vulkan, just install Windows with bootcamp. Or play a non-paper-mario game...
