Hi, yarsavenger! Hope you read this.
I think I've solved the problem, finally (fingers crossed). It was an issue with code signing.
If you:
- download the executable (version 1.1.6);
- move the file into the Application folder as requested;
- open it by clicking with the right mouse button (or Control + click);
- confirm "Open"...
...it should work, even on the latest OS!
I'm sorry it took me so long, but code signing on Apple is really very complicated.
Let me know if it works! :)
