Sorry about this! Mac builds were always a little volatile with the original GameMaker (a little less so now in GMS2), and unfortunately I kinda expected this would happen at some point. Apple has a habit of constantly breaking software with updates! If I can dig up the source files and make time to re-compile it with GMS2 then that might solve these issues for a time, but that isn't something I was planning on doing anytime soon. :<
