When you open apps on your Mac that can use the built-in camera, such as FaceTime, Photo Booth, or others, the camera is turned on automatically. However, if your camera doesn't work, this guide will walk you through various troubleshooting steps to get it up and running.

Common Issues and Their Solutions

There are several common issues you might encounter when using the camera on your Mac. Let’s look at each one and how to fix them.

Restarting Your Mac

If your camera isn't working, the first step you should take is to restart your Mac. This can often resolve the issue. Here’s how you do it:

Step 1: Click on the Apple menu in the top-left corner of the screen.

Checking if the Issue is Unique to FaceTime

Sometimes, the problem might be specific to FaceTime. Here’s how you can check:

Step 2: In FaceTime, check the Video menu to ensure you’ve selected the correct camera.

If the issue persists, move on to more advanced troubleshooting steps.

Advanced Troubleshooting Steps

Here are some advanced steps to try if the camera still doesn't work after restarting and checking the settings.

Forcing the Quit of AppleCameraAssistant and VDCAssistant

If the camera is still not working, you can force quit some system apps and services that might be causing the issue. Here’s how:

Step 1: Open Terminal. You can find Terminal via the Spotlight Search.

Step 2: In Terminal, type the following commands and press Enter after each one:

{sudo killall VDCAssistant}

Step 3: In Terminal, type the following command and press Enter:
