Your Mac has a webcam ready to use without any setup
Your Mac's built-in webcam—called the FaceTime camera on most models—works when ready in any app that needs video. You don't install drivers or flip a switch. When an app wants to use your camera, macOS asks your permission the first time, then remembers your choice. The camera sits in a small black dot at the top center of your screen, above the display.
The camera turns on only when an app requests it. A green light appears next to the camera lens when it's active, so you always know when you're being recorded. If you don't see that light, the camera is off.
Key Takeaways
- Your Mac's camera activates only when an app requests it, and a green light shows when it's recording.
- Video calls in FaceTime, Zoom, Google Meet, and similar apps use your camera automatically once you grant permission.
- You can check which apps have camera permission in System Settings under Privacy & Security, and revoke access anytime.
- If an app can't see your camera, restart the app first, then check that you granted permission in System Settings.
- Covering your camera with a physical cover or tape is the only way to block it completely when not in use.
Using your camera in video call apps
When you open FaceTime, Zoom, Google Meet, Microsoft Teams, or any other video call app, the camera usually starts automatically. The first time you use it, macOS displays a permission dialog asking "FaceTime would like to access your camera." Click Allow to proceed. After that, the app remembers your choice and starts the camera without asking again.
Once permission is granted, you'll see your own video preview on screen. Most call apps show a small preview window of yourself in the corner while you see the other person full-size. You can usually mute the camera by clicking a camera icon with a slash through it—this stops sending video without closing the app.
If the camera doesn't appear in a video call app, close the app completely and reopen it. If it still doesn't work, check your permission settings (see the section below). Some apps also let you choose which camera to use if you have multiple cameras connected—look for a camera or settings icon in the app's menu.
Checking and changing camera permissions in System Settings
macOS keeps a list of which apps can use your camera. You can see this list, add apps to it, or remove apps from it at any time. Open System Settings (the gear icon in your dock or Applications folder), then click Privacy & Security in the left sidebar.
Scroll down and click Camera. You'll see a list of every app that has asked for camera permission. A toggle switch next to each app shows whether it's currently allowed to use the camera. Click the toggle to turn camera access on or off for any app. The change takes effect when ready—you don't need to restart anything.
If an app you want to use doesn't appear on this list, it means you haven't opened it yet or you clicked Don't Allow the first time it asked. Open the app again and grant permission when prompted. If the app doesn't prompt you, try restarting your Mac.
Using your camera with Photo Booth or Screenshot tools
macOS includes Photo Booth, a straightforward app for taking photos and videos with your camera. Open it from your Applications folder (or search for it using Spotlight—press Command + Space and type "Photo Booth"). The app shows your live camera feed and lets you take still photos or record short videos. Click the camera icon to take a photo, or click the video camera icon to record. Your files save automatically to your Pictures folder.
You can also capture video from your camera using the Screenshot tool. Press Command + Shift + 5 to open the screenshot menu, then click Record Selection or Record Entire Screen. A small floating menu appears with a camera icon—click it to include your camera feed in the recording. This is useful if you want to record yourself while demonstrating something on your screen.
Troubleshooting when your camera won't work
If an app says your camera is unavailable or you see a black screen instead of video, start by closing the app completely and reopening it. Sometimes the camera gets stuck and needs to be released. If that doesn't work, restart your Mac—this clears the camera from memory and lets it start fresh.
Next, check your permission settings in System Settings as described above. Make sure the toggle for that app is turned on. If the app isn't listed at all, open it once and grant permission when prompted.
If multiple apps can't see the camera, or if Photo Booth shows a black screen, your camera may need a restart at the system level. Shut down your Mac completely (not sleep), wait 10 seconds, then turn it back on. This resets the camera hardware. If the camera still doesn't work after a restart, contact Apple Support—the camera hardware may need service.
Protecting your privacy while using your camera
The green light next to your camera is your main privacy indicator. If you see it on when you're not in a call or using an app, something unexpected is accessing your camera. Check which app is using it by opening Activity Monitor (search for it in Spotlight), clicking the CPU tab, and looking for the app name. Close that app when ready.
To prevent accidental camera use, you can cover the lens with a physical cover, a piece of tape, or a small sticker. This is the only foolproof way to block the camera completely. Some people use small sliding covers designed for laptop cameras, which you can buy online for a few dollars.
You can also disable camera access for apps you don't use. Open System Settings > Privacy & Security > Camera and turn off the toggle for any app that doesn't need it. This doesn't hurt the app—it just prevents that app from using your camera. You can turn it back on anytime.
Using an external camera instead of the built-in one
If you want to use a different camera—a USB webcam, a professional camera, or a phone connected as a camera—plug it into your Mac or connect it wirelessly. Most USB cameras work when ready without drivers. Open your video call app and look for a camera or settings menu. You should see an option to choose which camera to use. Select your external camera from the list.
Some apps let you switch cameras mid-call. Others require you to choose before you start. If your external camera doesn't appear in the list, make sure it's fully connected and powered on, then restart the app. If you're using a phone as a camera, make sure both devices are on the same Wi-Fi network and that the phone app supports Mac connection.
Frequently Asked Questions
Can I use my Mac's camera while the lid is closed?
No. When you close your Mac's lid, the display goes to sleep and the camera stops working. You need to open the lid to use the camera. If you want to use your camera while your Mac is docked, you'll need to connect an external USB camera instead.
Why does my camera look blurry or dark?
Clean the camera lens with a soft, dry cloth—dust or fingerprints can blur the image. If the image is too dark, make sure you have enough light in front of you. Most Mac cameras don't have a brightness adjustment in the camera itself, but many video call apps let you adjust brightness in their settings. Check your app's preferences or settings menu.
Does my Mac camera work if I'm not connected to the internet?
Yes. The camera itself works without internet—it's just a video input device. However, video call apps like Zoom or FaceTime need internet to send your video to other people. You can use Photo Booth or Screenshot to record video locally without internet, but you can't make video calls.
What if I see a camera permission dialog every time I open an app?
This usually means you clicked Don't Allow before, or the app was updated and lost its permission. Open System Settings > Privacy & Security > Camera and make sure the toggle for that app is turned on. If it's already on, try turning it off and back on again to reset it.
Can I disable my camera completely so no app can use it?
You can turn off camera access for every individual app in System Settings, but there's no single "disable all cameras" switch in macOS. The easiest way to may support your camera can't be used is to cover the lens with tape or a physical cover. This blocks the camera at the hardware level, regardless of what any app tries to do.
