Webcam Not Working On Mac: What Could Be The Cause?

It will say disconnected or unavailable if your MacBook camera isn't operating correctly. If the Camera on your MacBook isn't working, the "There is no connected camera" warning could pop up with any software. But don't jump to the conclusion that you need to "re-connect" the Camera or that there's a hardware problem that necessitates warranty service:

  • A camera settings app is not included with macOS. Most Mac camera apps have their own setting choices, so there's no physical or software on/off switch.
  • Even if you suspect a hardware problem, you can typically solve the problem of a Mac camera not working on your own with the help of a few simple procedures.

The following is a thorough list of tips for getting your Camera back up and running if it has malfunctioned.

Check the permissions on your webcam.

  1. If you're having problems with your Mac's Camera, the first thing you should do is verify the permissions for webcam use.
  2. Select System Preferences from the Apple option in the left corner of your Menu bar.
  3. Go to the Privacy tab under Security & Privacy.
  4. Make sure the app you wish to use has a checkmark next to it by scrolling down to Camera.

Using Terminal, enable your Camera.

It's possible that your Camera was in use by another app and did not exit properly, allowing the new app to use the webcam. As a result, you may need to use Terminal to terminate the process.

Open the Terminal program by going to Finder > Applications > Utilities > Terminal and typing in the following commands:

Sudo killall VDCAssistant

This command terminates the VDCAssistant process, which aids in the Camera's operation. We were prompted for our admin password for the command to take effect. Type it in when the Terminal prompts you.

You might alternatively use the command sudo killall AppleCameraAssistant.

Although this one may be exclusive to OS X, our Big Sur macOS could not detect the procedure.

Look for apps that are using the Camera at the same time.

We know that apps that use the Mac camera turn it on automatically. However, it's also worth noting that the Camera may only be used by one app at a time. So, if your Mac webcam isn't working, check to see whether you're being refused access to the Camera because another app is now using it:

  • From the Applications menu, select Activity Monitor.
  • Close any other apps or utilities that are currently using the camera (e.g., Skype, FaceTime, and Photo Booth)
  • If you're not sure which apps are accessing your Camera, save your work and dismiss all open apps to eliminate any possibilities.

Reboot your computer.

If leaving apps doesn't work, there's a risk that some background processes are accessing the Camera. A restart will probably fix the problem, restoring complete control of the Camera. To restart your Mac, follow these steps:

  • In the top menu bar, select the Apple icon.
  • Restart by clicking the Restart button.
  • To restart an M1 Mac, go to the Apple menu > Restart.

When FaceTime isn't working on your Mac, use Force Quit.

Restarting is effective, but it takes time and stops whatever you're doing, which may not be an option if you're in the middle of a crucial FaceTime conversation. Fortunately, there's a workaround for FaceTime not working on Mac that doesn't require a reboot and addresses the problem immediately. To Force Quit the process, use the following command line:

  • Go to Utilities Terminal Applications Utilities Terminal Applications Utilities
  • Type sudo killall VDCAssistant inside the terminal window.
  • If prompted, press Return on your keyboard and input your admin password.
  • Relaunch the app to see whether the webcam issue on Mac has been addressed.

On a Mac, fix the Skype camera that isn't working.

If you're wondering why my camera won't work on my Mac when I'm making Skype calls, Skype likely is to blame. If your Skype camera isn't working on your Mac, follow these steps:

  • Make sure you're using the most recent version of Skype.
  • If you've done all this and your MacBook still doesn't have a linked camera, reinstall the software.
  • Is the issue still present? If FaceTime isn't working on your Mac, follow the outlined steps. After that, restart your computer and test Skype once more.

Finally, make sure you're connected to the internet and that your speed is enough (at least 128 kbps, or 1 Mbps for HD FaceTime video calls). If you're having trouble with your internet connection, consider WiFi Explorer, a network analyzer that may help you diagnose and fix common network issues without hiring an expert.

WiFi Explorer evaluates your network environment (band range, signal quality, security status), detects channel conflict and coverage difficulties, and makes quick WiFi recommendations.

WiFi Explorer's visual graphs make it simple to analyze the issue at a look without having to delve into the numbers.

Reset the system controller on your Mac.

If none of the above seems to help and the Camera on your Mac is still not working, you can try resetting the System Management Controller (SMC). The SMC is in charge of several hardware tasks on your Mac, and rebooting it may solve your problems.

To reset the SMC on a MacBook (2017 or older), follow these steps:

  • Turn off your computer.
  • Make sure your power adapter is plugged in.
  • At the exact moment, press and hold the Shift, Control, and Options keys and the power button.
  • Allow 30 seconds before letting off the keys, which will restart the Mac.

Resetting the SMC on a new MacBook Air or Pro with the T2 security chip is more complicated and requires two steps. While performing the first step may solve the problem in some cases, completing both steps is often a more reliable method of resolving the Camera not working on the MacBook issue.

The first step in resetting the SMC on MacBooks (from 2018 or later) is to:

  • Turn off your Mac.
  • For 10 seconds, press and hold the power button.
  • Wait a few seconds after releasing the power button.
  • Restart the computer.

Check to see if the problem with your Mac webcam is still present. If the problem remains, move on to the next section.

On MacBooks (2018 or later), the second step is to reset the SMC:

  • Turn off your Mac.
  • Press and hold the right Shift key, the left Option key, and the left Control key for seven seconds after the computer has been switched off.
  • Press and hold the power button for seven seconds while still holding the keys.
  • Wait a few seconds after releasing everything.
  • To turn the Mac back on, press the power button once again.
  • If the problem with the MacBook Pro camera not working was caused by the SMC, whatever the problem was, it should now be fixed.
