Apple loves having proprietary stuff, so the only way you can compile something for macOS is if you have a Mac. You'll have to compile it yourself. Follow the SRB2 Wiki's CMake guide and you'll have a compiled version of the game for Mac.
https://www.jameds.org/SRB2/compile/ helped me with that, you'll probably find it useful too. I'm using 64-bit and OpenGL, but for me all the tailsball settings just do nothing and pressing shift makes Tails descend just like vanilla.
