Unable to 0pen Nikon NEF file from D810. Photoshop CS6 on MAC. Downloaded 8.6 version of Camera Raw Plugin
Which version of mac os x are you using?
Did you get camera raw 8.6 with adobe updates?
(Help>Updates from within photoshop cs6)
Which version of camera raw does photoshop say?
Photoshop>About Plug-Ins and click on the words Camera Raw
Did you use Nikon Transfer to get the nefs from camera to computer?
Using Help > Updates out of Photoshop brought all the software up to date and allowed me to open the D810 raw images. Thanks.
