How to Fix Webcam Not Working on Windows and Mac

A non-functional webcam can disrupt video calls and remote work. Most issues have straightforward solutions.

Check Privacy Settings

Windows 11: Settings > Privacy & Security > Camera. Mac: System Settings > Privacy & Security > Camera. Ensure camera access is enabled.

Update or Reinstall Drivers

Open Device Manager, find your camera, update the driver. If that fails, uninstall and restart to auto-reinstall.

Test in Multiple Apps

If webcam works in one app but not another, check app-specific camera settings. Close other apps using the camera.

Check Physical Connections

For external webcams, try a different USB port. For laptops, ensure no physical privacy shutter is closed.

When to Seek Help

If software fixes fail, the hardware may be faulty. Built-in laptop cameras require professional repair.
