I have made a simple JavaFx application, which reads/writes the txt file (the code is below). I have tested it on Windows platform (7 and higher). After I gave app my friend for test on Mac. But when we run it, it just does nothing. The GUI did not appear.
I tried run it through terminal (just "drag and drop" the icon to terminal, then enter in terminal. I don't know did I do right?) and terminal returned message "Permission denied". Can somebody explain what is require to run application, and what is not permitted exactly?
I found the similar question there but it does not have an answer...
