-  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:

-  The current version of Wine contains a partial implementation of dwrite.dll

-  We recommend that you run winecfg, add an override for dwrite in the
- Libraries tab, and edit the override mode to "disable".
