Since I had my D850, I used Nikon Transfer twice and it worked.
But today, in the third try, it did not work
The preference set is that, by default, when I connect the cable from the D850 to the Macbook Pro, it opens automatically Nikon Transfer 2
So I turned off the camera. I connected the cable to the laptop.
I turned on the camera.
It automatically opened Nikon Transfer 2
The application recognise in the Source tab the D850 and Slot 1
It chose the primary destination in my laptop as usual.
In the preference tab, it chooses new files only.
When I click on Start Transfer, nothing happens.
I waited about 15 minutes and still nothing happen.
What did I do wrong ?
what should I do to make it work?
Why it worked the first two times and not now ?
