Did you start X11.app first? Use Finder and look in Applications/
Utilities then click X11. Once it is running you will
see the X logo in the Dock, then start your app.


I get the same error with running X11.app

cannot connect to X server

Justin,
The 'terminal' launched by default in X.app is a xterm.
xterm is a x-client program.
x-client programs require a running x-server to display to and function.
X.app is a x-server program.
The x-server program can be either local (running on same machine as x-client), or remote (running on separate machine than client).


If X.app is running, the local xserver display is :0.0

To view the DISPLAY in both the Terminal.app terminal, and the X11.app Terminal, type:
env | grep DISPLAY


The terminal in Terminal.app does not have a xserver specified by default.
To have any x-client program launched from Terminal.app, and display on your local x-server, you will need:
1) set the DISPLAY variable in your Terminal.app window:
echo $SHELL


   a) if says /bin/bash, type:
     DISPLAY=:0.0
     export DISPLAY

   b) if says /bin/csh, type:
     setenv DISPLAY :0.0

2) start X.app

3) the x-client program to run from Terminal.app

Your initial post, you had #3 only.
Your second post had #2 and #3 only.
