Anyone else having issues? I have a Nikon D810, the latest LR CC, and using a MacBook Pro retina 2013 model. I'm also using the tether tools power boost for the USB 3 cable. The computer will recognize the camera and allow me to start shooting. Then it starts disconnecting several times throughout. I usually have to quit and restart LR CC. Very frustrating! Anybody have ideas or tips? Is it just me?
