I am having issues connecting my R8 to my Mac via the EOS Utility. I have the latest software and have gone through the user manual. The message I keep getting is:
"Communication with the camera via USB cannot be established.
Start EOS Utility after closing all the apps that communicate with the camera, and then turn on the camera again."
I am unaware of any apps that I have that would be trying to communicate with my camera in the background. Anyone know what's going on? Thanks in advance.
Solved! Go to Solution.

It is a problem that seems to have developed with the 13.4.1 update to Ventura.
I was able to sync my 1D X MkIII prior to that update and now I get that error.
If you are only looking to download images you could get a card reader. If you are wanting the tethering features then we have to wait for Apple to fix the problem.

So why do i have to wait for apple to fix it instead of canon just updating their broken program? Don't understand that... yes, maybe it's apples fault, that it's no longer working but what stops canon from fixing it?

I have often wondered why Apple keeps breaking other programs with every OS update?

The solution is to go to Settings -> Privacy and Security -> Camera and then disable all the apps that are given access to camera.
After this EOS Utility will start without an issue.
Best,

Have you tested this? I believe that setting is for the computer camera.

Yes I did test it. I'll see to record a video and can post it here. I think the moment you connect your camera to your Mac, it will be treated as an additional camera, together with the built-in one.

That wiould be good to see.
I tried it on my MacBook Air M2 Sonoma. Didn't make any difference with EOSU 3.17 - no connection either way.
I installed EOSU 3.16.1 - connects fine to my 1D X Mark III with or without disabling apps authorized to use the camera.

No - this doesn't work. I switched them all off to try anyway. In any event, those settings you refer to are for the camera in your computer, not your actual Canon Camera.

The only thing enabled for me is the Canon Eos Utility. I already disabled everything else, no luck.

Having the same exact issue. It's looking like it's a MacOS problem which hopefully gets addressed soon.
