Why is my Mac’s camera not working?
Your Mac’s camera may not be working due to a variety of reasons, including software issues, hardware problems, or conflicts with other applications. It’s possible that the camera is being used by another app or process, or that there’s a problem with the camera’s drivers or settings. In some cases, the issue may be caused by a physical problem with the camera itself, such as a blockage or damage.
To troubleshoot the issue, try restarting your Mac and see if the camera starts working again. You can also try closing any apps that may be using the camera and then reopening them. If the problem persists, you may need to try more advanced troubleshooting steps, such as resetting the System Management Controller (SMC) or reinstalling the camera drivers.
