I haven't been able to get it to work. I have 2019 MacBook Air runnign Big Sur. Using Canon 80D. EOS Utilty NOT running. Installed EOS Webcam utility. Camera not visible in ANY services listed. I've tried reinstalling a few times and finally gave up. I know it's not the USB cable because I can run the camera from my Mac (EOS Utility) with the USB cable I have. Sure would be nice to have it work. No other cloud services running either.
Hey so I just got off the phone with support because I was having this EXACT issue. Make sure you download EOS Utility 3.13.10 for macOS, not the Utility 1.0. You may have to pick a different camera to find it (go to the "Choose a Search Area" search bar at the upper right and type in a camera name). For example, I have a T5, but it only showed up as an option for the T6. Download the EOS Utility 3.13.10 for macOS software, and after installation make sure to restart your computer. It should work after that.
I believe the answer for now is that it is not compatible. I have read through almost all comments and here is what I have experienced.
There isn't software available for Big Sur right now. Someone else said they have it, but I doubt they could get it again if they delete it. Maybe they could share a liok to the download. Might have been a beta version and then they upgraded OS.
I am running M1 MBA and have been messing with this for 3 days and finally got it to work. I think its because I am running the rosetta version of Zoom and EOS Webcam Utility. When I go to downloads for any of my cameras it says there isn't anything for Big Sur, but does say that Catalina is detected (I assume it is recognizing something through Rosetta).
If you need EOS Webcam Utility then I would suggest holding off from updating to Big Sur. I am disappointed that Canon released the full version of EOS Webcam Utility around the same time as Big Sur and didn't release a version for that OS.
Final clarification. I am running EOS Webcam Utility and Zoom on Big Sur, but I think it is working only because of Rosetta which is used with New (Fall 2020) M1 Macs.
