JFileChooser not working on mac os?

Question

macOS

fFileChooser opened the folder perfectly on windows, on macos it doesn't want to, the cursor just spins endlessly and nothing happens.

public void getDir() {
        chooser = new JFileChooser();
        chooser.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY);
        chooser.showSaveDialog(null);
        String fileLocation = String.valueOf(chooser.getSelectedFile());
        File dir = new File(fileLocation);
        readFiles(dir);

        }
