Canon EOS R50 UVC Webcam Not Working Properly on macOS v26 (Tahoe)

Hi everyone,

I'm using the Canon EOS R50 as a streaming camera for OBS via UVC mode. After updating to macOS v26 (Tahoe) on my MacBook M3 Pro, the camera is no longer working correctly.

Issue Details

The Mac detects the camera as “Canon Digital Camera”, but fails to initialize the video feed.
The camera stays in STBY (standby) mode, even after selecting it as the source in OBS.
I was able to get it working once after a full system restart, but:
- If I disconnect the camera or switch sources, it gets stuck in STBY again.
- Only a full restart temporarily resolves the issue.

Tested Setup

macOS v26 (Tahoe) – issue occurs.
macOS v15 (Sequoia) – UVC mode works perfectly (tested on a different device).
Canon EOS R50 Firmware – tested on both v1.4.0 and v1.1.0.
Camera is set to Movie Mode with USB connection set to “Video calls/streaming”.

Has anyone found a workaround or patch for this issue on macOS Tahoe? Any help or insights would be appreciated!

Thanks in advance!
