EOS Webcam Utility Problems with Sequoia: Camera works in EWU but not in other apps

[webcam_user_21]

I recently installed MacOS Sequoia (15.1) and installed EOS Webcam Utility Pro for Sequoia (2.2.24).

My camera works within the Webcam Utility app--but that's the only place it works. In Zoom, Meets etc EOS Webcam does not appear within the list of available cameras.

When I open "System Settings"-->"General"-->"Login Items & Extensions", in the "Allow in Background" section, "Canon USA Inc" has two items. The slider is blue, IE on. In the list of Extensions, I don't see anything related to cameras, Canon or EOS.

I've tried uninstalling, reinstalling and rebooting multiple times without luck.

Any help would be much appreciated. I really depend on my Canon as webcam.

Good to hear!

Though I have 15.1.1 installed and it's still not working for me. Just tried with EOS Webcam Utility Pro v2.3 and no luck, it's still not installing extensions for me.

Which ver of Webcam Utility are you using?

I used 2.3.15 that came I. The 2.3 download.

Problem solved! 2.3.15 working for me. I had to get my corporate IT function to allow the system extensions to be installed. Our corporate anti-virus / system control software was preventing this from taking place.
