Comment 75 for bug 1835296

Holger, have you tried running it without a system-wide ngspice installed?

I just tried installing the ngspice-30.pkg, which installs to /Applications/ngspice/ and now I get no crash! Running it inside lldb shows that it's using the code models from the system-wide ngspice instead of the bundled ones:

If I rename /Applications/ngspice to /Applications/ngspice_old, it crashes. And looking at which images is loaded I get:

And here comes the important part: If I manually replace the code models in /Applications/KiCad/kicad.app/Contents/PlugIns/sim/ngspice/ with the ones that was installed from the ngspice-30.pkg, it works without crashes!

So my conclusion is that the MacOS packaging is breaking those files.
