CR3 Previews Not Working in Finder After macOS 15.4 and 15.4.1 Updates

Hello,

I hope this response helps you resolve your issue. I am experiencing the same difficulty in QuickLooking my .cr3 files. Currently, I am compelled to manually open each .cr3 file using Lightroom.

The only solution I have discovered is to zoom in slightly while using QuickLook, and the image will be displayed. I trust this information is timely and helpful.

opino igual, pero me han dicho en apple que tenemos que ponernos en contacto con canon para que lo habiliten ellos, me suena rarísimo pero eso me han dicho, que el resto estan obligados a actualizarse con las actualizaciones de apple

An understanding of software development and testing is not a prerequisite for owning a Mac - quite the opposite! I also have the same problem with CR3 files, which has slowed down my work considerably.

I have the same problems with the same symptoms - CR3 files in column view in finder show as a black box. Changing the dimensions of the window makes the image appear but if you move away and return to the file it is a black box again.

Something that has not been mentioned before is that if the file is stored elsewhere, the problem does not seem to occur. I use Dropbox and .CR3 files that are only stored on Dropbox do not seem to be affected.

MacBook Air M2, macOS 15.4.1

Adobe Bridge is my work-around for those with access but there is a way to view in Finder under the following conditions:

The preview pane in the last column of the Finder window does (VERY eventually) display a preview instead of a black box on my machine (specs to follow) IF the user manually rescales the finder window and releases the mouse-click. Upon releasing the mouse button, the preview of the .CR3 displays. Not satisfactory at all, but hopefully a breadcrumb for Apple Support ...

I had the same issue on my M1 macbook. A previous poster suggested making sure your display setting preset was in photography mode. That did the trick for me. However, Now a Sequoia update to 15.5 seems to have fixed the Finder bug. I'm in Apple XDR Display and my CR3 file in finder can be previewed.

Thanks. Looking at Canon CR2 files, when I resize the Finder window, the image appears, but goes back to a black rectangle for the next image. So, it seems necessary to repeat the resize process for every image. Not a user friendly way to search through hundreds of images. One more fix that is needed in Sequoia.

I just ran into this same issue Cr3 files, from my Canon R5. I am running MacOS 15.5, MacBook Pro 13" M1. I found a workaround which is in Bridge, right click and open the file in Camera Raw from there I can open the file into Photoshop. (26.7.0). I downgraded Photoshop to 26.6 same issue. All my other files are fine at this point CR2, and Jpeg..

This worked for me:

Finder > View > Show View Options

Then check > Show Item Info

If that doesn't work then the other solutions listed may work better for you but his was a super quick and simple solution.

CR2 works for you? I have all the same problems listed above for CR3 with CR2, from 5Dmii and 5Dmiii

Yes, slightly zooming in on the black window will result in the image loading (albeit very slowly), but if you zoom back out to see the whole image, the blackness returns. This needs to get fixed.

This issue has totally ruined my work flow. doesn't anyone have a work around until apple can get its act together?

I have the same problem with monochrome Leica DNG-Files (M Type 246)

Wow! Not ideal but thanks for that tip. It works

same with me. my entire project got stalled.Anyone from Apple here?
