[gradsusr] GrADS on M1/M2 Mac

[Sim Aberson]

Paul,

I reported this many months ago on this forum, and got no response.  My
workaround has been to not upgrade XQuartz past 2.8.4.  I issue the
following commands:

  mkdir /tmp/.X11-unix
  sudo chmod 1777 /tmp/.X11-unix
  sudo chown root /tmp/.X11-unix/
  /Applications/Utilities/XQuartz.app/Contents/MacOS/X11.sh &

Once XQuartz starts running, I open an Xterm (not a regular terminal),
and run GrADS from there.  After that, I can run GrADS from either
terminal or Xterm.
