Hello,

I am trying to reach the help center for xcrysden.
I have followed the install instructions on my MAC below and have
received this error message:

application-specific initialization failed: no display name and no $DISPLAY
environment variable
Error in startup script: can't read "xcrys(platform)": no such variable

   - *Mac OS binary packages:*
   (compiled on macOS Mojave 10.14)
      - Shared: xcrysden-1.6.2-macosx-shared.tar.gz
