macOS support for CR3 flies from EOS R5 mark ii

[cdel3133]

I am unable to open CR3 files from my new R5 mark ii on my Macbook pro using Preview or (Mac) Photos.

My camera is using latest firmware. My computer is using latest OS (Sequoia 15.2 (24C101)). I rebooted the computer a couple of times.

"Get info" correctly reads the file type, size, other data. However, it can't give a preview and the icon has no image.

I was able to import the CR3 files into Photos, but I cannot see previews or open them for editing. I was able to export CR3 files, but not jpgs, from Photos.

I am able to open the files (including the ones exported from Photos) using Canon's Digital Photo Professional 4.

In researching the problem online, I was able to download someone else's CR3 file from an R6 - it opens ok.

I realize I am probably part of a small group that buys the R5 mark ii and uses Mac Photos for editing. My previous camera was a Canon 5D mark iv and I never had problems with this computer and workflow.

I encountered this problem recently and made postings about the problem on Canon and on Apple support/discussion forums. The problem seems to be an Apple problem, and my posting there has resulted in a thread at https://discussions.apple.com/thread/256248724?sortBy=rank&answerId=261856023022&page=2

There is still no resolution to the problem, and I'm running Tahoe 26.3.1 on my MacBook Pro.

It seems to be unique to the R5M2. I have no problem with my R6M3 files, and that is a later model camera.
