Sorry, I don't have a mac and people I know who have a mac don't have GM2. If you or somebody have it and can compile it for me I'd be grateful to send the source code. Thanks for the interest!
I tried to make an executable on my Mac but it didn't work. I also looked for help online and no luck. I honestly have no idea what to do.
:( I'm really sorry. I'm attempting to port it/make a new version in Unity, so I hope there will be a bigger better cross-platformer TCYD soon.
