In the end I'm using homebrew (package) versions of ntp and gpsd. What versions? The That's a new one. I assume it sends standard NMEA? The main difficulties were setting I'm not sure that is hard. Just put the device path on the gpsd command line. increasing I'm not sure why you would need that. and dealing with Mac env restrictions I'm not sure why you would need that. I still can't get ntpshmemmon to run properly- permission denied to I've never had that problem on a mac. Maybe some new Apple specific hardening. Any solutions? Can it work? Yes. Do I understand your problem? No. cgps shows great data Good. ntpq -p shows the GPS data updating ( no PPS) You are skipping a lot of dettails. Please rung gpsdebuginfo and send the output here. In general, if ntpshmmon is not working, you can stop right that and not look at anything else NTP. One question is how to test it properly Run gpsdebuginfo, and send the result herre. Also try the Toubleshooting Guide: https://gpsd.io/troubleshooting.html I want the Mac system clock to rely on the gps No, you want it to rely on ntpd, which may rely on GPS for part if its data. I tried setting the date time system prefs to use 127.0.0.1 , No, you want ntpd to control your system time, not macOS. the If that is what you are doing, that is wrong. Any suggestions for testing? See above. Does anyone know if PPS is supported by the Radio? Probably not, but the output of "-ND 4" that I already asked for would tell you.
