      You may want to get winetricks:
        brew install winetricks

        By default Wine uses a native Mac driver. To switch to the X11 driver, use
        regedit to set the "graphics" key under "HKCU\Software\Wine\Drivers" to
        "x11" (or use winetricks).

        For best results with X11, install the latest version of XQuartz:
          https://xquartz.macosforge.org/
      EOS
