#570 Mac OSX 10.15.7 Crash on launch

[Anonymous]

Simply that, I downloaded it, launch it, and it shows an icon for a second, then closes.

Running XtrkCAD-bin from shell produces this log:

$ /Applications/xtrkcad.app/Contents/MacOS/XtrkCAD-bin ; exit;

(XtrkCAD-bin:3649): Gtk-WARNING **: 11:32:15.484: cannot open display:

The display is installed from XQuartz which is a dependency - did you install it? And after installing it, did you logout/login (or restart)?
