Nikon raw NEF files & OS 15 Quicklook feature

TidBITS Talk

I’m having an issue viewing NEF files on my MacBookPro M4 Max laptop when I press the spacebar to “Quicklook” a Nikon raw file. The image that appears in the window is all black. After doing some troubleshooting I found that if I grab the frame of the window to adjust the size, the image appears. This only happens with Nikon NEF files from the D300 all the way up to Z8 camera raw files. Any other files open as expected with PDF, Word, Nikon JPG, Canon raw CR2, and Sony ARW files. I also discovered that this only happens when the display presets in System Settings are set to “Apple XDR Display (P3-1600 nits)” or “Apple Display (600-nits)”. All of the other display presets work with my Nikon raw files as they should. Anyone else seeing this?

There are reports (e.g. MacRumors) of this happening for Canon CR2 and CR3. This is the first I have seen regarding Nikon. Seems that it does not affect everybody and there is some variation in hardware. I get exactly what you described my M3 MBP and CR2 files, but on my Intel iMac it is really weird - black for the preview in Finder’s column view, but Quick Look works as expected.

Report to Apple with Feedback Assistant.

Your comment about display presets is new to me. I will experiment.

Thanks gilby. Let me know what you find out with the presets. I have filed a support ticket with Apple. It seems that many people have had one issue or another with the quicklook feature for quite some time. I didn’t have any problems with quicklook on my 2013 Mac Pro prior to Apple not supporting the newer raw files. It is now stuck on Mohave as the last supported OS. I added Raw Right Away to it when I upgraded to a newer camera that wasn’t supported in Mohave. It works great. I may need to install it on my laptop and see if that works.

Presets do make a difference!! With my CR2 on M3 MBP macOS 15.4.1, with preset changed as you say to, for example, Photography P3-D65, I now see the images in QuickLook and in Finder view by icon or gallery. The only black rectangles are in Finder’s view by columns.
