I'm most of the way done connecting my GPS to my MBP OS X Monterrey , that's to
persistence and some help from Gary Miller
In the end I'm using homebrew (package) versions of ntp and gpsd. The GPS is
from an Icom IC-705 radio. The main difficulties were setting the correct
serial/usb device for the GPS to connect to , increasing the shared memory, and
dealing with Mac env restrictions
I still can't get ntpshmemmon to run properly- permission denied to connect to
SHM1&2
Everything is running from sudo/root
Any solutions?
cgps shows great data
ntpq -p shows the GPS data updating ( no PPS)
One question is how to test it properly
I want the Mac system clock to rely on the gps
I tried setting the date time system prefs to use 127.0.0.1 , the turning off
WiFi and resetting the clock manually then restore to automatically w 127.0.0.1
- not sure this is working right
Any suggestions for testing?
Does anyone know if PPS is supported by the Radio?
Thanks
Marc
