 10.15.7 - running on an Intel 2.3GHz Quad-Core cpu w/16GB DDR3 RAM.

 Well, yeah. I debugged this problem on a 2016 Intel MacBook Pro on Mojave
 10.14.6. That's why I said it probably **''wouldn't''** show up on an
 Apple Silicon device. It ''will'' show up on an Intel Mac on Catalina or
 lower.

 I also suspect that this wouldn't show up on macOS 11+, Intel or Apple
 Silicon. I think Apple changed `libcxxabi` in that release to tolerate
 multiple definitions of type info data, by defining the preprocessor
 symbol `_LIBCXXABI_FORGIVING_DYNAMIC_CAST` when building `libcxxabi`. And
 in fact, when I try KiCad on an Intel Mac running Sonoma without the
 patch, it works just fine. For this reason, I suspect that help from
 upstream would be less than forthcoming, since KiCad 7 officially doesn't
 support any version of macOS prior to 11. But, one will never know unless
 one actually asks. The fact that exceptions would still be broken on Intel
 even with `_LIBCXXABI_FORGIVING_DYNAMIC_CAST` is probably a point in favor
 of asking.
