Your Mac's camera is off by default, and you turn it on through System Settings
Your Mac's built-in camera (called the FaceTime camera on most models) is not blocked by a physical switch like some laptops have. Instead, macOS controls it through software. To use it for video calls, recordings, or any other purpose, you need to open System Settings, navigate to Privacy & Security, and grant camera permission to the app you want to use.
The camera itself does not have an "on" switch in the traditional sense. What you are actually doing is telling macOS which apps are allowed to access it. Once you grant permission to an app like Zoom, Google Meet, or FaceTime, that app can turn the camera on whenever you open it. You can revoke that permission at any time, and the app loses access when ready.
Key Takeaways
- Your Mac's camera requires permission from each app before it can be used, and you grant this permission in System Settings under Privacy & Security.
- You can see which apps have camera access and remove permission from any app at any time.
- If an app says your camera is not working, the first step is to check whether you have given that app permission in System Settings.
- A green light next to the camera lens means the camera is actively recording or streaming right now.
How to grant camera permission to an app on your Mac
Open System Settings by clicking the Apple menu in the top-left corner, then select System Settings. Click Privacy & Security in the sidebar. Scroll down and click Camera. You will see a list of apps that have requested camera access. Toggle the switch next to any app to turn its camera access on or off.
If the app you want to use is not on the list, it has never requested camera access yet. Open that app, look for a video call button or settings menu, and try to start a video call or enable the camera. The app will then ask for permission, and you can click Allow. After you allow it once, the app will appear in the System Settings camera list.
What to do if an app says your camera is not available
The most common reason an app cannot find your camera is that you have not given it permission. Go to System Settings > Privacy & Security > Camera and check whether the app's toggle is on. If it is off, turn it on. If the app is not on the list at all, open the app and try to use the camera again — this will prompt the permission request.
If the app has permission but still cannot see the camera, restart the app completely. Close it entirely (not just minimize it), wait a few seconds, and open it again. If that does not work, restart your Mac. A small number of older apps do not work with newer versions of macOS, so check the app's website or support page to see whether it is compatible with your Mac's operating system version.
How to see which apps are using your camera right now
When an app is actively using your camera, a small green light appears next to the camera lens at the top of your Mac's screen. This light cannot be turned off or disabled — it is a hardware indicator that the camera is recording. If you see the green light but did not start a video call, an app is using your camera without your knowledge.
To find out which app is using the camera, click the Control Center icon in the top-right corner of your menu bar (it looks like a rectangle with sliders). You will see which app is currently accessing the camera. Close that app or end the video call to stop the camera from recording. If you do not recognize the app, check your running applications and close anything suspicious.
How to remove camera access from an app you no longer use
Go to System Settings > Privacy & Security > Camera. Find the app in the list and toggle its switch to off. The app will no longer be able to access your camera. You can turn it back on at any time if you change your mind. Turning off camera access does not uninstall the app or affect any other functions — it only prevents that app from using the camera.
If you want to be extra cautious, you can remove camera access from every app except the ones you actually use. This is a reasonable choice if you are concerned about privacy. The trade-off is that if you install a new app and want to use its camera feature, you will need to go back to System Settings and turn on permission first.
The difference between camera permission and microphone permission
Your Mac has separate controls for camera and microphone. An app can have permission to use your camera but not your microphone, or vice versa. If you are on a video call and the other person cannot hear you, check System Settings > Privacy & Security > Microphone to see whether the app has microphone permission. If you are on a video call and the other person cannot see you, check the Camera list instead.
Some apps request both permissions at the same time, and some request them separately. You can grant one and deny the other. For example, you might allow Zoom to use your camera but not your microphone if you prefer to use external speakers and a separate microphone.
What happens if you deny camera permission and then change your mind
If you clicked "Don't Allow" when an app first asked for camera permission, the app will not ask again automatically. To give it permission later, go to System Settings > Privacy & Security > Camera, find the app on the list, and toggle its switch on. The next time you open the app and try to use the camera, it will work.
If the app is not on the list even though you denied it before, open the app and try to use the camera feature again. This will re-trigger the permission prompt, and you can click Allow this time. After you allow it, the app will appear in the System Settings camera list.
Frequently Asked Questions
Can I cover my Mac's camera with tape or a sticker?
Yes, many people do this for privacy reasons. A small piece of tape or a camera cover will block the lens completely. The green light will still appear if an app tries to use the camera, but no video will be recorded. Keep the cover thin enough that it does not damage the screen when you close the laptop.
Why does my camera show a black screen even though the app has permission?
The most common cause is that another app is already using the camera. Your Mac can only send camera video to one app at a time. Close any other apps that might be using the camera — check video call apps, messaging apps, and recording software. Restart the app that is not working. If the problem continues, restart your Mac.
Does granting camera permission mean the camera is always on?
No. Granting permission only means the app is allowed to turn the camera on if you ask it to. The camera stays off until you actually start a video call or enable it in the app's settings. The green light will only appear when the camera is actively recording or streaming.
Can I give camera permission to an app without giving it microphone permission?
Yes. Camera and microphone permissions are separate. Go to System Settings > Privacy & Security and adjust each one independently. An app can have camera access but no microphone access, or any other combination you choose.
What if I see an app in the camera permission list that I do not recognize?
Turn off its camera access when ready by toggling the switch to off. If you do not know what the app is, search for its name on your Mac or check your Applications folder. If it is something you installed and no longer use, you can uninstall it. If you do not recognize it at all, it may be a system app that came with macOS — turning off its camera access will not cause problems.
