Test your webcam in your operating system's built-in camera app first

The fastest way to check if your webcam works is to open the camera app that came with your computer. On Windows 10 and 11, search for "Camera" in the Start menu and click the app. On Mac, open Spotlight (Command + Space), type "Photo Booth", and launch it. Both apps will show you a live feed from your webcam within seconds — if you see your face or the room behind you, your hardware is working.

If the app opens but shows a black screen, your webcam may be disabled in your system settings or blocked by privacy controls. If the app won't open at all, your computer may not recognize the device. Either way, the next steps depend on which problem you have.

Key Takeaways

  • Open your operating system's built-in camera app (Camera on Windows, Photo Booth on Mac) to see a live feed from your webcam in under a minute.
  • A black screen usually means your webcam is disabled in settings or blocked by privacy controls, not broken hardware.
  • Check your privacy settings on Windows (Settings > Privacy & Security > Camera) and Mac (System Settings > Privacy & Security > Camera) to see which apps have permission.
  • Test your webcam in a video call app like Zoom or Google Meet to confirm it works in real-world conditions before troubleshooting further.
  • If your webcam still does not work after checking settings and permissions, restart your computer and check the Device Manager (Windows) or System Report (Mac) for hardware errors.

Check your privacy and permission settings on Windows

Windows 10 and 11 let you control which apps can use your webcam. Open Settings, go to Privacy & Security, and select Camera. You will see a toggle at the top that says "Camera access" — make sure it is turned on. Below that, you will see a list of apps with permission to use your camera. If the app you want to use is listed but the toggle next to it is off, turn it on.

If Camera access is turned off entirely, no app will be able to use your webcam, even if the hardware is working. Turning it on will let Windows and your apps detect the device again. After you change any setting here, close and reopen the camera app to see if it works.

Check your privacy and permission settings on Mac

Mac requires you to give permission to each app that wants to use your camera. Open System Settings, click Privacy & Security, and select Camera. You will see a list of apps that have requested camera access. If the app you want to use is there but does not have a checkmark next to it, click the app name and turn on the permission.

If you do not see your app listed, it has never asked for permission yet. Open the app and try to use the camera feature — Mac will prompt you to allow it. Click Allow, and the app should then be able to access your webcam. If Mac does not prompt you, the app may not support your camera or may have a bug.

Test your webcam in a video call app

Video call apps like Zoom, Google Meet, and Microsoft Teams have their own camera test tools that show you exactly what your webcam will look like to other people. These tests are more realistic than the built-in camera app because they use the same code path that a real call would use.

In Zoom, click your profile picture, go to Settings, select Video, and you will see a preview window. In Google Meet, start a new meeting, click the camera icon at the bottom, and you will see a preview before you join. In Teams, click your profile picture, select Settings, go to Devices, and look for Camera. If you see a live preview in any of these apps, your webcam is working in conditions that match a real call.

Check the Device Manager on Windows for hardware errors

If your camera app shows a black screen and your privacy settings are turned on, your computer may not be recognizing the webcam as a working device. Open Device Manager by right-clicking the Start button and selecting Device Manager. Look for a section called Cameras or Imaging Devices and expand it.

Your webcam should be listed by name — often something like "USB Camera" or the brand name. If you see a yellow exclamation mark or a red X next to it, Windows has detected the device but found a problem. Right-click the device and select Update Driver. Windows will search for a newer driver online. If that does not work, uninstall the device, restart your computer, and Windows will reinstall it automatically.

If your webcam does not appear in Device Manager at all, the hardware may not be connected properly. If it is an external USB camera, unplug it, wait 10 seconds, and plug it back in. If it is built into your laptop, the connection may be loose inside, and you may need to contact the manufacturer or a repair shop.

Check the System Report on Mac for hardware errors

On Mac, open System Settings, click General, and select About. Click System Report. In the window that opens, click USB in the left sidebar and look for your camera in the list. Your built-in camera will usually say "FaceTime HD Camera" or similar. External USB cameras will show the brand name.

If your camera appears in the list with no error message, the hardware is recognized and working at the system level. If it does not appear at all, the connection may be loose or the device may not be compatible with your Mac. If it appears but shows a warning, try unplugging it (if external) or restarting your Mac. If the problem persists, contact the camera manufacturer or Apple Support.

Restart your computer and check for driver updates

Many webcam problems go away after a restart because the operating system reloads drivers and resets connections. Shut down your computer completely, wait 30 seconds, and turn it back on. Then open your camera app or video call app again and test the webcam.

On Windows, you can also check for driver updates by opening Device Manager, right-clicking your camera, and selecting Update Driver. Choose "Search automatically for updated driver software" and let Windows search online. On Mac, open System Settings, click General, and select Software Update to check if macOS itself needs an update — camera drivers are often included in OS updates.

Frequently Asked Questions

Why does my webcam show a black screen even though the app opens?

A black screen usually means your camera is disabled in privacy settings, blocked by another app, or covered by a physical privacy shutter. Check your privacy settings first (Settings > Privacy & Security > Camera on Windows, System Settings > Privacy & Security > Camera on Mac). If that is on, try closing other apps that might be using the camera, or check if your laptop has a physical shutter or cover over the lens.

How do I know if my webcam is broken or just disabled?

Open your operating system's camera app and check your privacy settings. If the app opens and shows a live feed, your camera is working. If the app opens but shows a black screen and your privacy settings are on, the camera is likely disabled in software. If the app will not open at all or your camera does not appear in Device Manager (Windows) or System Report (Mac), the hardware may be broken or disconnected.

Can I test my webcam without opening an app?

Yes. On Windows, search for "Camera" in the Start menu and open the app — no installation needed. On Mac, open Photo Booth from Spotlight. Both show a live preview in seconds. You can also test in any video call app like Zoom or Google Meet without joining an actual call — they all have preview windows.

What should I do if my webcam works in one app but not another?

Check the privacy settings for the app that is not working. On Windows, go to Settings > Privacy & Security > Camera and make sure the app has permission. On Mac, go to System Settings > Privacy & Security > Camera and check the same thing. If the app is not listed, open it and try to use the camera — your operating system will prompt you to allow it.

Do I need to install drivers for my webcam to work?

Most built-in laptop cameras work without installing anything — Windows and Mac include drivers for common models. External USB cameras usually work the same way. If your camera is not recognized, check Device Manager (Windows) or System Report (Mac) to see if Windows or Mac found a driver automatically. If not, visit the camera manufacturer's website and read the driver for your model and operating system.
