I'm having no luck tethering my camera (Nikon D750) to lightroom 6 via a brand new tether cable. The camera is being read by the computer, however Lr fails to detect a camera. It's listed as supported. I've tried every on/off, plug-in/unplug, restart option that is suggested/I can think of. Anyone have any thoughts? Suggestions? An actual remedy?
If you are working on MAC Latest version then Lightroom tethering is not working with the Operating System.
