I have a recently purchased Canon Mark II 6D, with EOS3 imprt software with Catalina and the Mac cant read the camera via Canon factory USB cable

Another idea: why not simply take out the memory card from the camera and either use a USB card reader or the one on your Mac (if yours has one)? Much easier than dealing with trying to tether the camera. And, doing it this way will result in the card reader/card icon showing up on your desktop where you can open it and view the pics right there or import them into a photo editing app. You would not need the Canon software at all.

Apple product teams and engineers are not here — just fellow users. Apple supports the EOS 6D Mk II with camera raw support in Catalina. That puts the problem back in Canon's lap with that EOS 3 utility, or a damaged USB cable.

Is there a current update for the EOS 3 utility software on the Canon site? Do you have access to another Mac running Catalina 10.15.2 to test if you can read and import the image on that hardware?

Have you tried importing the images with the macOS Image Capture app (found in Applications)?

Is the camera seen by that?

FWIW, my experience is the Nikon and Canon apps seem a little slow

on the draw when it comes to compatibility updates (like many months after a

new OS release).

As I said, the easy way is to take out the camera card and use a USB card reader. You do not need the camera, nor do you need their software. Canon is known to be excruciatingly slow updating their software after OS updates. You can simply insert the card reader; its icon should show on the desktop (make sure you have your Finder preferences set to show external disks); open that and you can choose to view them, import them to any photo editing app, or whatever.

That is the situation with image capture

it sees the camera but does not respond.

On the other hand Camera works perfect with Capture one. (but its trial version)

so anyone any solution ?

Did you try Apple's Image Capture utility with your connected camera?
