The Anatomy of a Mac Webcam
Before we diagnose the problem, let’s take a closer look at the webcam itself. Macs come equipped with a built-in FaceTime HD camera, located above the display. This camera is responsible for capturing high-quality video and photos, making it an essential feature for video conferencing, online meetings, and even selfies.
