Crash when starting ARB

[guest]

Hello,

I've been trying to install ARB this morning and keep getting this error. I've tried the Macport and homewbrew methods of installation, but both give the same error.

(base) MACP80253:~ u1993000$ arb

ARB terminated abnormally
[press ENTER]

Looking at previous tickets there seems to be a crash when they have already loaded data, which I haven't gotten to the GUI to do. When I try another install using Macport, it gives me this output.

Thanks and stay safe!

Error: Can't open display: :0

This is not an ARB-specific problem. I think there is a general problem with your X11 server installation and/or configuration.

You should run into the same problem when e.g. trying to start a terminal using the command

xterm

When you fixed the problem for xterm, arb will most likely run as well.

We currently recommend the homebrew version of arb. So you might want to switch back..

Similar problems often occur when installing arb via homebrew.

Example error message:

The problem is not arb specific: your X display does not work. You will get the same error when you start any other X program.

Your problem is similar to ​https://stackoverflow.com/questions/37826094/xt-error-cant-open-display-if-using-default-display

There the problem had been fixed by rebooting.

If the problem persist after reboot, please send the output of the following commands to arb@…:

xterm

echo $DISPLAY
