800E tethered to MAC ?
You can tether with CAPTURE ONE PRO even though they don't officially support it yet. In order to make it work you will have to do the following...
1. Install Nikon Camera Control Pro 2
2. Find the file Type0006 Module.bundle AND Type0007 Module.bundle from:
Library/Application Support/Nikon/Camera Control Module
From Finder, do:
Applications/Capture One (show package contents) Contents/MacOS/CaptureCoreServer (show package contents)
Copy both Type0006 Module.bundle AND Type0007 Module.bundle into this folder:
Copy fileLibNkPTPDriver.dylib from the same location into:
Library/Application Support/Nikon/Camera Control Modules
and place the fileLibNkPTPDriver.dylib into the Camera Control Modules folder"
Do NOT run Nikon Camera Control Pro 2 when running Capture One.
A reboot may be required for everything to function correctly.
When you update Capture One, you have to repeat the whole process.
