I am sorry to tell but, as you might well know, in that regard, I'm not keen to any other platform than GNU/Linux ... :(
however you may try hack the server prefix; from jackd --help output:
--autoconnect OR -a <modechar>
where <modechar> is one of:
' ' - Don't restrict self connect requests (default)
'E' - Fail self connect requests to external ports only
'e' - Ignore self connect requests to external ports only
'A' - Fail all self connect requests
'a' - Ignore all self connect requests
