8 Days Ago   A webcam can be easily misused—and sometimes hijacked by malicious software. While macOS has been generally free of malware that can tap into the camera, and Apple has a hardware-linked green LED that can’t be disabled in software when the camera is active, you may still want to prevent the camera from being used at all.
