Could you please confirm which version of Lightroom are you using?
Which version of Mac do you have?
5.7.1 Sorry about that
I am using Lightroom 5.7.1
Which version of Mac is it?
Is it Mac El Capitan?
This was a known issue with Nikon's SDK on Mac El Capitan though it has been resolved in Lightroom 6.4 release.
I believe there is no solution for Lightroom 5.7.1 for tethering.
Your options are :
- downgrade your OS
- Upgrade Lightroom version
- Use Nikon's tethering tool (if available)
Wow. It didn't work before I upgraded to El Capitain either. It was suggested I upgrade my OS system and I did. I can't go backwards unless I do a clean install and lose my system. I wished I had known this before going through all these updates. Very discouraged. Thank you for your time.
