In general, if Emacs crashes from time to time, my advice is to run it
under a debugger at all times, and when it crashes, produce a
backtrace and post it together with the bug report.  If you can afford
leaving the crashed session under the debugger, please do, as we might
have some requests for you to look inside the crashed session and show
values of some variables.

It's your OS function.  I don't use macOS, but every modern OS records
some information about a crash of every program in some place, so
searching the Internet and/or your system documentation will certainly
reveal how to find that place and look up the crash info from there.

Thanks.
