Q: X11

While trying to open my 3D drawing software (Moi v 3), I get the following message: "The application X11 could not be opened. An error occurred while starting the X11 server: failed to activate core devices."

MacBook Pro (Retina, 15-inch, Late 2013) OS X El Capitan version 10.11.6

How to fix this?
