How to Fix Camera Not Working on Mac - 11 Quick Fixes

If your camera is not working on Mac, it can instantly interrupt video calls, online meetings, or recordings. The good news is that in most cases, this issue is not caused by hardware failure. Instead, it's usually related to software conflicts, app permissions, or system settings. In some cases, using an external webcam for Mac can also help you quickly bypass hardware-related limitations.

In this guide, we'll walk you through 11 quick fixes to get your Mac camera working again, most of which take just a few minutes to try.

Part 1: Why is the Camera Not Working on Mac?

When the camera in the Mac is not working, understanding the real cause helps you fix problems in the right way.

1. Camera Permission Disabled

After the launch of macOS Mojave, Apple has implemented powerful privacy controls. All applications must be approved by the user before they use the camera hardware. Permission is denied permanently unless it is later changed.

2. Another App is Using the Camera

macOS restricts camera access to a single application at a time. Background applications frequently retain camera control invisibly. A minimized Zoom window blocks FaceTime from accessing the camera entirely.

3. macOS System Bug

Software updates occasionally introduce unintended consequences. Camera functionality sometimes suffers following major system updates. Apple typically releases patches to address these issues.

4. Screen Time Restrictions

Screen Time settings can restrict camera access for specific applications. Restrictions remain active until someone with the passcode modifies them.

5. Hardware Failure

Physical damage requires professional intervention. Liquid exposure corrodes internal components. Impact damage loosens cable connections. Software troubleshooting cannot address mechanical failures.

Part 2: Quick Check Before Fixing the Camera

Before trying advanced fixes, it's helpful to quickly check whether software or app conflicts, or hardware failure, are causing the issue.

1. Test the Camera in FaceTime

Opening FaceTime reveals immediate camera status. A functional preview confirms working hardware. Problems are likely in specific third-party applications.

2. Test the Camera in Photo Booth

Photo Booth activates camera capture immediately upon launch. Visible self-image confirms basic camera operation. A black screen indicates deeper issues.

3. Check if the Camera is Detected in the System

Click the Apple menu and select "About This Mac." Click "System Report" and locate "Camera" in the sidebar. Absent listings suggest macOS cannot communicate with camera hardware.

After completing these checks, you can use the quick reference table below to identify the issue and apply the appropriate fix.

Part 3: How to Fix a Camera Not Working on Mac Quickly?

The following are known ways of repairing the camera on your Mac. Begin with the easiest solutions and proceed onto more complex solutions. 

Method 1: Restart Your Mac

The temporary processes in the system are killed, the memory is cleared and in most instances, the small software glitches are resolved by a simple reboot. The stuck camera processes often release upon a clean reboot.

Step 1: Save all open work

Step 2: Select Restart from the Apple menu.

Step 3: Allow the Mac to complete restoring.

Step 4: Restart the camera application and test.

In many cases, the Mac camera not working issue is resolved by restarting the device.

Method 2: Quit All Apps that may be turned off using the Camera

Since, one application can use the Mac camera at a time, when there are a lot of applications attempting to capture the camera, one or more applications will fail to capture the camera.The Zoom, Teams, FaceTime, or even browsers with webcam permissions may create conflicts.

Step 1: Use Command + Tab to switch between open applications.

Step 2: Close any application that may be accessing the camera, such as Zoom, Skype, Teams, FaceTime, Slack, Chrome, or Safari.

Step 3: Alternatively, click the rightmost button for each application on the Dock, then select Quit.

Step 4: Reopen the application requiring the camera.

Method 3: Re-open the App that Needs the Camera

There are instances when apps such as Zoom, Teams, or FaceTime cannot automatically initialize the camera when opened. The problem of the app failing to initialize can be resolved by fully stopping and restarting the app.

Step 1: To completely quit the app (not just close the window), press Command + Q.

Step 2: Allow processes to clear, 10 seconds.

Step 3: Restart the app and make sure the camera is recognized.

Method 4: Enable Camera Permissions

The issue with the iMac camera not working is often related to permission settings. In macOS, an unauthorized application must be explicitly granted permission to use the camera. If permission was not initially granted to set up, or it was revoked by mistake, the camera will not appear in that app.

Step 1: Click the Apple menu, then select either System Settings (macOS Ventura and beyond) or System Preferences (older macOS).

Step 2: Go to Privacy and Security, then select Camera.

Step 3: Toggle ON the switch beside any application that uses the camera, such as Zoom, Teams, or Chrome.

Step 4: Reopen the application after authorization.

Method 5: Disable Screen Time Restrictions for the Camera

When the Screen Time feature is enabled on the Mac, especially on parentally controlled or managed computers, it can block access to the camera for specific apps or block it altogether.

Step 1: Go to Apple menu, then System Settings, then Screen Time.

Step 2: Click the left panel, then click Content & Privacy.

Step 3: Select App Restrictions or Allowed Apps.

Step 4: Make sure that the camera is turned on and switch it on where necessary.

The account administrator can be contacted if you are unaware of the Screen Time passcode.

Method 6: Update MacOS to the Latest Version

Apple is known to release regular updates to macOS that contain bug fixes for system components, such as the camera driver. If the camera failed on the MacBook after an update to macOS, there is a patch that could have fixed the problem.

Step 1: Select the Apple menu >  Go to System Settings >  then choose General >  Now click on Software Update.

Step 2: Click Update Now if it has an update.

Step 3: Have the Mac update itself and install the update.

Step 4: Reboot on completion of installation.

Method 7: Force Quit Camera Processes (VDCAssistant/Apple Camera Assistant via Terminal)

The VDCAssistant and Apple Camera Assistant processes handle camera communication in macOS. If either of them becomes unresponsive or crashes, their termination causes macOS to restart them. This is a good way to resolve the problem of the camera mac not working when there is no clear reason why.

Step 1: Applications > Open > Utilities > Terminal or Spotlight Search.

Step 2: Enter the next command and press Enter: sudo killall AppleCameraAssistant VDCAssistant

Step 3: Type the Mac administrator password as required.

Step 4: Go to Close Terminal, then restart the camera application.

Note: The Apple Camera Assistant may not be seen on more recent Macs with the macOS Monterey or later. This is normal. The VDCAssistant component merely has to be started.

Method 8: Close Camera-Related Processes in Activity Monitor

Activity Monitor provides an alternative way to end the processes related to the camera, because some of them are not comfortable with the graphical interface but find it easier in the Terminal, not requiring the use of command-line tools.

Step 1: Open Activity Monitor, then Applications, then Utilities, then Activity Monitor.

Step 2: On the search bar on the upper right, there is VDCAssistant.

Step 3: Find the process and press the X button (Force Quit) at the top.

Step 4: Repeat if Apple Camera Assistant appears.

Step 5: Relaunch the camera app.

Method 9: Boot Your Mac in Safe Mode

Safe Mode restarts the Mac with only very basic system components. It removes all third-party login items and extensions. This will help determine whether an application or extension is interfering with the camera.

For Apple Silicon Macs (M1, M2, M3, M4):

• Shut down the Mac completely
• Keep pressing and holding the Power button until you see the loading startup options.
• Click the startup disk, then press Shift and click Continue in safe mode.

For Intel-Based Macs:

• Shut down the Mac and press the Shift key right away.
• Shift at the appearance of the login screen.
• Log in and test the camera.

When the camera is in Safe Mode, something is running, or a startup item is causing the issue. Boot up again and delete new programs.

Method 10: Reset NVRAM/PRAM

NVRAM is a store of system settings. One can also reset it to adjust the camera issues due to corrupted system preferences. Macs based on Apple Silicon have another way of NVRAM and do not have to be rebooted manually.

Step 1: Shut down the Mac completely

Step 2: Press Power, and then hold Command + Option + P + R at once.

Step 3: Hold the keys for approximately 20 seconds, or until you hear two startup tones on older models.

Step 4: Unscrew the keys and enable normal startup.

Step 5: Test the camera after login

Method 11: Reset SMC (Intel-Based Macs Only)

The SMC manages low-level hardware functions, including camera initialization and USB power delivery. A reset clears stuck hardware states that prevent the camera from starting. This method resolves persistent issues with the Mac Pro camera not working on Intel machines.

MacBooks with T2 chip (2018+):

• Power off the Mac
• Hold Control + Option + Shift on the left side for 7 seconds
• Keep holding and add the Power button for 7 more seconds
• Release everything, pause briefly, and press Power

MacBooks without T2 chip:

• Shut down the Mac
• Hold Shift + Control + Option + Power together for 10 seconds

• Release all keys and start normally.

Apple Silicon Macs lack a traditional SMC. A standard restart achieves comparable results.
