This could be determined by "ulimit -n" or "getconf OPEN_MAX".
Best regards, Michael.

That's a different limit (resource limit vs. size of a file descriptor set).

Itʼs possible to raise FD_SETSIZE at compile time on macOS (to 4096 if
memory serves), so the only reliable way to test this is to expose
FD_SETSIZE to lisp. poll(2) anyone? ;-)
