I installed the „gv“ port (ghostview). Worked. I can give gv on the command line (shell prompt). But I’m getting:
Christophs-MBP:~ kuku$ export DISPLAY=:0 Christophs-MBP:~ kuku$ xhost + xhost: unable to open display ":0" Christophs-MBP:~ kuku$ gv gv: Unable to open the display. Christophs-MBP:~ kuku$ I thought, X11 apps can run against the macOS desktop server, can’t they? Or do I have to run an extra X11-server? — Christoph
