After quite a lot of investigation, I discovered that when running on MacOS, in addition to the usual setup steps, you need to have WIFI enabled in order for your location to be obtained.

Apparently Apple sometimes doesn't use IP geolocationing and resorts to visible SSID geofencing.

You can reliably trigger this by turning WIFI on / off. You don't need to connect to a SSID, just turning on WIFI is enough.

Symptoms :

1) checkPermissions() returns LocationPermission.always

2) isLocationServiceEnabled() returns true

3) Geolocator.getCurrentPosition(desiredAccuracy: LocationAccuracy.medium) hangs until timeout, then returns null

4) An exception is thrown (LOCATION UPDATE FAILURE:Error reason: (null)Error description: The operation couldn’t be completed. (kCLErrorDomain error 0.)).

(tested with MacOS Sonoma 14.5 on a Mac Mini M1)

Perhaps it would be useful to try replicating this and putting some note in the documentation.
