gpsd client for macOS

[Bryan Christianson]

I have released GPSDConfig-1.0.2, a gpsd client that runs on macOS 10.14.6 
(Mojave) through to macOS 14 (Sonoma beta).

The application will generate a boot configuration for gpsd, based on the user 
selected serial device. In addition, there is a flag to defer starting gpsd 
until chronyd is running.

I wrote the software as a request from radio amateurs who require timing 
accuracy on their Macs better than 1 sec but in the absence of an internet 
connection.

GPSDConfig will generate a refclock directive for chronyd enabling it to 
receive the gps timestamps from gpsd. Unfortunately there is no native PPS 
implementation for macOS so the accuracy is limited, but within the bounds 
required by these amateur radio enthusiasts.

If anyone has had success with PPS on macOS I'm all ears :)

The software can be downloaded from https://whatroute.net/gpsdconfig.html
