Canon R6 CR3 Files are Not able to be seen in PREVIEW

I didn't read the all the posts for this thread but have some experience with EOS RP and EOS R5 using macOS Catalina. Not all CR3 files are created equal. For example, Catalina RP CR3 files (in CRAW) work fine whereas the R5 CR3 do not.

Factors to consider (i.e. experiment with) are compressed versus uncompressed RAW as well as whether HDR is enabled.

For Catalina, I developed a workaround to create custom icons for EOS R5 CR3 files (CRAW, HDR enabled, CR3+HEIF generated). Have a look here. I imagine that the same approach would work with Big Sur.

See below for Finder screenshots.

P.S. HIF files should be renamed with an HEIC extension in order to open with Preview in macOS X Catalina

No member of the Apple product teams will ever respond here. It is a public site.

You can send direct feedback to the macOS product team including your camera model, firmware, and the lense you were using to generate the CR3 image. I say lense because one of the two Apple CameraRAW support bundles lists every vendor's known lense in it. That was a surprise to me.

Neither dialabrain nor I can reproduce your issue of total R6 CR3 image blackout with multiple M1 and Intel Macs between us.

My Canon EOS R6 .cr3 sample file below.

After Big Sur 11.2 update I can open, view and edit that it in Photos.app 6.0 and also view it in QuickLook and Preview. GraphicConverter can also open it with only Apple CoreImage enabled (LibRaw also handles that unlike the old dcraw).

But apparently for some strange reason other Big Sur 11.2 installs fail to open it.

Yes, it works now when Apple intoduced CR3 support to Mac, iPad and iPhone on Feb 2nd 2021. Do the following:

1. Ensure that you have the latest OS in the device(s).
2. Open the Apple Photos app in the device, close all other apps and leave the Photos app running idle for a couple of hours.

This fixes the problem. Photos app makes presuamable some corrections and updates to your photos library, therefoe it takes a while.

Have now experimented have to import photos using MacBook or they don't display on iOS so can only assume photos on MacBook is generating a preview that iOS can read not ideal!!

One should never assume…

iPad Air 2 - iPadOS 14.4. Same image I previously posted from an iMac.

This could be a problem rooted to my Photos library in iCloud. Out of the 16 most resource consuming processes in my Mac, 8 are related to Photos or iCloud. However, there are no runaway processes and the Mac is not overheating.

I will now let my Mac run idle at least overnight and see what happens.

In System Preferences > Software Update > Advanced, do you have this selected? Apple pushes the MRT and XProtect bundles this way, and it would not surprise me if they did so with the two relevant RAW bundles:

I don't have a "BEST" guess. I downloaded a couple RAW sample files from…

Additionally they do not work in Photos. Yes I can find a work around, but that's not what I paid for and I'm more than just a bit ******. This is not good customer service for a photo centric software and hardware provider. I'm not at all satisfied

I don't know what more I can do. I posted a screen shot showing the R6 RAW files in Preview. I have now checked three of my Macs that are running Big Sur 11.2 and they all can open the R6 files. That doesn't lead to a conclusion that there is a bug. Rather that there is an issue local to your machine.

I hope you can sort yours out.

Apple is dependent on the information that they receive from Canon for RAW support. As we are fellow users. we cannot possibly know if that information is complete for the R6 yet, or if it remains a work in progress with more f(x) to appear later.

Canon has issued R6 product advisories as a v1.1.1 firmware update for the R6 in Sept 2020, and another firmware update v1.2.0 in Nov 2020. The expected compatibility with Big Sur 11.2 may depend on firmware currency in your camera, though I have no way of knowing that A Priori.

The R6 raw images that I (and dialabrain) downloaded and that work in Quick Look, Preview, Affinity Photo, but not as Finder icons are based on R6 firmware v1.0.0.
