RAW NEF files not showing or working in Photos in Big Sur

I'm importing RAW NEF files from my Nikon Z6 II into Photos on Big Sur and they don't show a thumbnail and says an error has occurred when I try to open them. Info shows they are RAW NEF and the Geo location data. I can import them into Affiniti OK directly from the SD.


I'm only shooting RAW and not the JPEG.

MacBook Pro 15″, macOS 11.0

If you're resourceful you can install EXIFTOOL and use a terminal session to change the exif information. Here's what I have to change on all NEF's from the Nikon Z6 2.


  1. Download and install EXIFTOOL from https://exiftool.org/
  2. Copy all NEF files to a folder on the mac from the camera.
  3. Open a terminal session and change path to the folder where you copied the NEF's. Ex. cd Downloads (These are simple Linux commands).
  4. Run this line in the terminal: exiftool -overwrite_original -Model="NIKON Z 6" *.NEF

You should now see the NEF files thumbnails begin to populate on the mac finder folder.


NOTE: exiftool modifies the exif information for camera model that was embedded in the NEF file to "NIKON Z 6", from "NIKON Z 6 2".

The sensors and the resolution of the NIKON Z 6 and NIKON Z 6 II are identical, so the same RAW development should work (provided the lenses are the same as well).


I checked, how the RAW support is installed on macOS 11. Previously, several system versions ago, the RAW support has been installed as separate files for each cameras in the RawCamera.bundle. We could simply fake an additional RAW support file and reindex the RAW support. This worked well with the RAW support for Aperture. But the separate files do no longer exist. There are still the directories for RAW support, but the RAW support seems to be hard coded into one file inside the bundles.


/System/Library/CoreServices/RawCamera.bundle/

/System/Library/CoreServices/RawCameraSupport.bundle/

/System/Library/Assets/com_apple_MobileAsset_RawCamera_Camera/


Tagging the RAW images with the wrong camera model name seems to be the only way to fool the system, but doing this, we are mutilating our image files. We should keep the originals RAW files safe and just modify copies, and rename them, so we are aware of the fact, that the files have been modified and can revert to the previous versions, if Apple is ever going to release RAW support for the Nikon Z6 2.
