This looks like the same problem I'm having on FreeBSD. Its

I work around that by applying a patch to make ARG_MAX tunable on
FreeBSD (haven't yet upstreamed that though), but not sure how to tweak
that on macOS.
ARG_MAX on macOS is set to 256*1024 on macOS [1], and kern.argmax is also a readonly
sysctl. Briefly looking over the xnu source tree leads me to believe that making ARG_MAX
unable there is even more tricky than on FreeBSD. Just increasing ARG_MAX and recompiling
xnu might work though. Then again, most apple boxes tend to not run self-compiled kernels,
so I would just go with your second suggestion.
Probably a better way would be to somehow reduce length of the
command
line.
