Webcam Not Working on Windows 11 or Mac
Most webcam failures are permissions or another app holding the camera. Open the webcam test after each step.
Privacy shutter and keys
Check for a physical slider over the lens and a camera key (often F8/F10) that disables it.
Permissions
Windows: Settings → Privacy & security → Camera → allow access and desktop apps. macOS: Privacy & Security → Camera → enable your browser. Browser: address bar → Camera → Allow.
Close other apps
Only one app can use a camera on many systems. Quit Teams, Zoom, OBS and the Camera app.
Drivers
Device Manager → Cameras (or Imaging devices) → update or uninstall and restart. For USB webcams, try another port without a hub.
Settings guide
See our webcam settings guide for brightness and resolution, and Zoom camera fixes.
