GameMaker Studio 2.3...
Thank you anyway. Sigh. :/
Have you tried this?

Hi again, DreadDecripth.
It took me a while, but I did not give up - as promised!
I should have fixed the issue with code signing that was preventing my game from working on the latest OS. If you:
- download the executable (version 1.1.6);
- move it into the Application folder (or any other folder other than the Download foder);
- open it by clicking with the right mouse button;
- confirm "Open"...
...it should work. :)
Let me know how it goes, if you want!
