This works:
syslog.openlog(logoption=syslog.LOG_PID, facility=syslog.LOG_USER)
syslog.syslog(syslog.LOG_NOTICE, 'QQQ test log')
I see the "QQQ test log" when I run syslog command.
And I can reproduce that logging.handlers.SysLogHandler does not work.
I added debug to the SysLogHandler() code and see that it does indeed write
into the /var/run/syslog socket.
I suspect that macOS /var/run/syslog does not implement the RFC that this code
depends on, but that a wild guess.
I suggest that you write your own handler that uses syslog.syslog() and use
that.
