- Hold these keys for 10 seconds.
-
Release all keys and turn your Mac back on.
-
For Apple Silicon Macs:
Just restarting your Mac will automatically reset the SMC.
Remove Third-Party Applications
If you have recently installed third-party applications that use the camera (like webcam enhancers or virtual backgrounds), try removing them to see if that resolves the issue. Conflicts may arise from such software interfering with your webcam functionality.
Advanced Fixes for Webcam Issues
If the basic troubleshooting steps have not yielded results, consider these advanced solutions:
Using Terminal Commands
Advanced users can try using Terminal to reset the webcam’s settings:
- Open Terminal from Applications > Utilities > Terminal.
- Type the command
sudo killall VDCAssistantand press Enter. You may need to enter your administrator password. - This command kills the process that handles webcam functionality and forces it to restart.
Consult Apple Diagnostics
You can use Apple Diagnostics to check for hardware issues, including your webcam:
- Disconnect all external devices except keyboard, mouse, display, and Ethernet connection if applicable.
- Shut down your Mac.
- Turn it back on and immediately press and hold the D key until you see the diagnostics screen.
- Follow the instructions that appear on the screen and check for any reported issues.
Reinstall macOS
If everything else fails, consider reinstalling macOS. This should be your last resort as it may result in data loss if not done correctly. Ensure you back up all your important files before proceeding. You can use macOS Recovery to reinstall the operating system without affecting your files.
To reinstall macOS:
- Restart your Mac and hold down Command + R immediately after pressing the power button.
- Select Reinstall macOS from the utilities window.
- Follow the on-screen instructions to proceed with the installation.
When to Seek Professional Help
If you’ve tried all of the above troubleshooting steps and your webcam is still not functional, it may be time to seek professional assistance. There could be underlying hardware issues that require diagnosis and repair by a certified technician.

What should I do first if my webcam isn’t working on my Mac?
If your webcam isn’t functioning, the first step is to check for any obvious issues. Make sure that your Mac’s camera is not blocked or covered. Look for any physical obstructions that could be interfering with the lens. Additionally, ensure that the application you’re using has permission to access the camera. You can check this in System Preferences under Security & Privacy, then Camera.
If the camera is not blocked and permissions are set correctly, try restarting the application. Sometimes the software may encounter a temporary glitch that can be resolved by simply quitting the app and reopening it. If that doesn’t work, a full restart of your Mac can help clear existing processes that may be hindering webcam functionality.
How can I check if my camera is recognized by my Mac?
To verify that your webcam is recognized by your Mac, you can use the built-in application called “Photo Booth.” Open Photo Booth from your Applications folder; if the camera is working, you should see yourself on the screen. If you encounter an error message or cannot see your video feed, it suggests that your Mac isn’t recognizing the webcam.
Another way to check is to visit “System Information.” Hold down the Option key and click on the Apple menu, then select “System Information.” Under the “Hardware” section, find “Camera” to see if it’s detected. If it shows that no camera is available, there may be deeper hardware issues that need addressing.
What can I do if my webcam is recognized but not displaying video?
If your webcam is recognized but isn’t displaying video, ensure that no other application is currently using the camera. Applications like Zoom, Skype, or FaceTime may hold exclusive access to the camera, preventing other apps from using it. Close any open applications that might be utilizing the webcam, then try again.
If that doesn’t resolve the issue, consider resetting the PRAM or SMC on your Mac. These resets can resolve hardware-related issues that affect your system’s performance, including the webcam. Instructions for resetting PRAM and SMC can be found on Apple’s support site specific to your Mac model.
Are there software updates that might resolve my webcam issue?
Yes, outdated software can often be a culprit in webcam issues. To check for software updates, go to the Apple menu and click on “System Preferences,” then select “Software Update.” If updates are available, install them. Many updates include bug fixes and improvements that may enhance your webcam’s functionality.
Additionally, ensure the application you are using is also up-to-date. Sometimes specific applications may have known issues that are resolved in newer versions. Updating both macOS and the involved applications can offer a comprehensive fix to webcam-related problems.
What if my webcam still isn’t working after trying all troubleshooting steps?
If your webcam remains non-functional despite troubleshooting, it may indicate a hardware issue. In this case, you should consider contacting Apple Support or taking your Mac to an authorized service center. They can perform diagnostics to identify any hardware malfunctions or technical failures that are not easily recognizable.
Another option is to use an external webcam while you troubleshoot the internal one. Many third-party webcams are compatible with Mac computers and can serve as temporary solutions. However, keep in mind that even external webcams may require drivers or permissions that should be configured correctly.
How can I ensure my privacy while using my webcam?
To protect your privacy while using your webcam, always be mindful of the applications you install and the permissions you grant them. Review the settings for each application to ensure that only trusted services have access to your webcam. Consider regularly checking your System Preferences under Security & Privacy to manage application permissions effectively.
Additionally, you can use physical camera covers or stickers to block the lens when the camera is not in use. This simple precaution can prevent unauthorized access to your webcam, ensuring that you maintain privacy when your camera is not actively in use.
