If your Mac camera light is always on, there are a few simple steps you can take to try and fix the problem. These steps include quitting any apps that may be using the webcam and disabling camera access permission. If these steps don’t work, your computer may have been hacked.

The camera turns on as soon as you open an app that uses a camera such as FaceTime, Zoom, or Photo Booth, and a green light will be next to the lens to indicate that it is indeed on. The camera (and again, the green light) both turn off when you close or exit all apps or features that were using the camera.
