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

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.

It works for me now, but I have to be sure to connect the camera in first and then open Photos. If photos is already open, then the files can not be seen. This is not a problem, just a process that works just fine.

You might want to try the free XnView MP app to browse your R6 images.

I did nothing but the let the Photos app open running idle in the MacBook Air, iPad Pro and iPhone 11 Pro with all other apps closed, connected to wifi and with full battery. That fixed the problem in all three devices in a couple of hours. I spyed with activity monitor what was happening in the MacBook Air while it was ”idle”. There were 6 to 8 Photos related or iCloud related processes actively running, and they fixed the problem.

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.

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.

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.

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 did spell it out. The camera has to be connected to the computer before you open Photos. If you open photos before connecting the camera the images will not upload. This is the only change I had to make that is different from my EOS R. The R6 seems to need this. process or it will not play.

I simply added this RAW CR3 to the Photos application. There was no upload or settings. Just a Get Info on the image in Photos.

You should also post an EtreCheck report.

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

FWIW, the R6 CR3 files work in Photos for me.
