A DESCRIPTION OF THE PROBLEM :
When closing a scene unsing CMD-Q on MacOS, I want to let the user confirm to save the project modifications to file. This works fine using Scene.setOnCloseRequest() on Windows, but not on MacOs. How can I do the same on MacOs?
stage.setOnCloseRequest(event -> {
            if (!acceptClosingFrame()) {
                event.consume();
            }
        });
