Symptoms
- Video calls show a black screen where your camera feed should be
- An app reports it can't find or access the camera
- The green camera indicator light doesn't turn on when expected
- Camera works in one app but not another
Likely causes
- CommonThe app not having camera permission granted in macOS privacy settingsSimilar to microphone access, macOS requires explicit per-app permission.
- CommonAnother app already using the camera in the backgroundOnly one app can typically access the camera at a time.
- PossibleA temporary software glitch with the camera processRestarting often clears this.
- PossibleA physical camera cover or accessory blocking the lensEasy to overlook, especially with privacy covers.
- Less commonA hardware fault with the camera module, more likely on older MacBooksThis becomes more likely if no app or setting combination restores the camera.
What to do
- Check System Settings > Privacy & Security > Camera and make sure the app you're using is toggled on.
- Quit other apps that might already be using the camera (video calling apps, browsers with an open video tab).
- Check for and remove any physical camera cover if you use one.
- Restart the Mac to reset the camera process.
- Test the camera in a different app (like Photo Booth) to narrow down whether it's an app-specific or system-wide issue.
- Check for macOS and app updates, since camera-related bugs are occasionally fixed in updates.
- Reset the SMC and NVRAM/PRAM (Intel Macs) if the issue persists across all apps.
- If the camera doesn't work in any app after all these steps, it likely needs professional inspection.
Tools and parts
- None required
When to call a pro
If the camera doesn't work in any app after software troubleshooting, an Apple-authorized shop can check for a hardware fault with the camera module.
