On your powerful Mac devices, webcam not working is possible and can be fixed easily with:

1. Close Other Camera Apps 

If you are using multiple camera apps on your Mac, switching from one app to another can cause the Mac camera not working. For instance, if you open the Zoom app without closing the FaceTime camera, your Zoom camera will not work. Therefore, close all other camera apps before using your camera.

• Type Activity and select the Activity Monitor. 
• Double click on all other apps using the camera and select Quit on the window that pops up.

• Power off your Mac. 
• Hold the following keys for seven seconds — ⌘ Cmd + ⌥ Option + ⇧ Shift. 
• While holding these keys, hold the power button for another seven seconds. If your Mac has turned on, it will turn off now. 
• After a few minutes, turn on your Mac.

• Power off your Mac. 
• Hold together ⌘ Cmd + ⌥ Option + ⇧ Shift. 
• Also, hold the power button for ten seconds. 
• Power on your Mac. 

3. Stop the VDC Assistant and Apple Camera Assistant Processes

The VDCAssistant and AppleCameraAssistant are two processes that perform webcam duties in the background on your Mac. If these processes stop working correctly, it can cause the Mac camera not working issue. 

Mostly, when a process crashes, the system automatically restarts. Sometimes, the automatic restart won’t work, and you have to manually kill processes with a terminal command, either searching for it in Spotlight or going to Applications > Utilities. Type the following command, and then press Enter:

sudo killall VDCAssistant;sudo killall AppleCameraAssistant

You need to enter your admin password and then try to use the webcam again. If you aren’t comfortable with terminal commands, you can also restart your Mac.

Screen Time is a core macOS feature that monitors your Mac’s usage. It is a macOS parental control handler that includes restricting access to the webcam. If you have restricted webcam access, your Mac camera will not work.

To confirm the Screen Time restriction problem, follow these steps:

• Go to System Preferences > Screen Time > Content and Privacy and click on Camera. 
• If the Camera is disabled under the Apps tab, you can authenticate or change the settings.
