The server is started automatically by .Nm launchd during system startup. .Pp The .Fl d option causes .Nm notifyd to log debugging messages to a log file. Messages are not logged to ASL to avoid potential deadlocks, since the ASL system makes use of the .Xr notify 3 system. .Pp The default log file is .Pa /var/log/notifyd.log . An alternate log file path may be specified following the .Fl log_file flag. .Pp The .Fl shm_pages Ar npages option sets the number of shared memory pages used for passive notification. The default is one page. If a value of zero is specified, shared memory is disabled and passive notifications are performed using IPC between the client and the server. .Sh SEE ALSO .Xr notify 3 .
