Thanks! I have a PC also so it's not a huge problem for me-- I'll just play it on my other computer.
maybe it's a game maker issue? that doesn't support newer mac versions? I can try later tonight, I'm still on 10.11 i believe
yea turned out I uploaded a build that got corrupted
For anyone who sees this, it turns out the launcher craps out because there are no execute permissions set on it... I ended up having to run the game through the terminal, Deios.app/Contents/MacOS/Mac_runner or something like that
