I can't get my D810 to tether to a MacBook Air 13" (High Sierra 10.13.6) laptop. Once the (new Nikon) USB lead is connected to both, the camera just locks up, and also is not recognised by any software.
The USB bus in System Report does not show it, neither does Image Capture, Bridge, Finder, etc.
s/w I have tried -
Capture One 20
Nikon Camera Control Pro II
Camera RC Deluxe
Any help or suggestions would be very appreciated!
