How to Fix Webcam Not Working on Windows & Mac — Complete Guide

⚡ Quick Answer

If your webcam isn't working, start by testing it in a browser-based webcam tester. If it shows a live image, the issue is app-specific (permissions or settings). If no image appears, check camera privacy settings, update drivers (Windows), or restart the camera service (Mac).

Step 0: Test Your Webcam First

Before anything else, test the webcam in your browser. This bypasses all third-party apps and tests the camera at the browser/OS level.

Image appears in the test? Hardware is fine. Jump to the app/settings section for your OS.
No image in the test? The camera isn't being accessed. Continue from Fix 1.

Fixing Webcam Issues on Windows

Fix 1: Check Camera Privacy Settings

Settings → Privacy & Security → Camera. Make sure "Camera access" is On. Enable individual apps (browser, Zoom, Teams) in the list below. This resets after major Windows updates.

Fix 2: Update or Reinstall the Camera Driver

Device Manager → Cameras (or Imaging devices) → right-click webcam → Update driver. If updating doesn't work: Uninstall device → restart. Windows will attempt to reinstall automatically.

Fix 3: Close Apps Using the Camera

Windows only allows one app to access the webcam at a time. Close all video apps (Zoom, Teams, Skype, Discord, OBS) and check the system tray for background apps. Reopen only the app you need.

Fix 4: Disable and Re-enable the Camera

Device Manager → Cameras → right-click webcam → Disable device → wait 10 seconds → Enable device. Test in the browser tool.

App-Specific Fixes (Windows)

Zoom: Settings → Video → Camera dropdown → select correct camera.
Teams: Profile → Settings → Devices → Camera.
Google Meet: Lock icon in Chrome address bar → Camera → Allow.

Fixing Webcam Issues on Mac

Fix 1: Check Privacy Settings (macOS)

Apple menu → System Settings → Privacy & Security → Camera. Enable the toggle for Safari, Chrome, Zoom, etc. Restart the app after toggling.

Fix 2: Force Quit Apps Using the Camera

Press Command + Option + Escape. Close FaceTime, Zoom, Teams, or any app that may be holding the camera.

Fix 3: Restart the Camera Daemon

Open Terminal and type: sudo killall VDCAssistant — press Enter, enter your password, then test the webcam again.

Fix 4: Boot in Safe Mode

If the webcam works in Safe Mode, a third-party app or kernel extension is causing the issue. Identify and remove it.

Frequently Asked Questions

Why is my webcam not working on Windows 11?

The most common causes are camera privacy settings being turned off (Settings → Privacy & Security → Camera), a driver issue after a Windows update, or another app holding the camera open.

How do I fix webcam not working on Mac?

Go to System Settings → Privacy & Security → Camera and enable access for your browser and apps. If that doesn't help, try running sudo killall VDCAssistant in Terminal.

Why is my webcam showing a black screen?

A black screen usually means another app is using the camera, browser permissions are blocked, or the camera driver has crashed.

My webcam works in the browser test but not in Zoom — why?

Zoom doesn't have camera permission, or the wrong camera is selected in Zoom's settings. Go to Zoom Settings → Video and select the correct camera.
