In recent years, people have discovered that the WebCam of laptop computers has the opportunity to quietly record videos without the user's knowledge. Hackers can use some programs to invade your system and use your WebCam to "steal" users' surroundings.
Therefore, some WebCam lens protection caps appear on the Internet, which can manually block Webcam shooting. However, Apple recently published an article reminding users not to install the WebCam cover on the MacBook, because when the computer is closed, the display may be damaged.
Because the gap between the display and the keyboard is designed to be extremely narrow, if you close the Mac laptop with the camera cover closed, it may damage the display. Covering the built-in camera may also interfere with the ambient light sensor, causing functions such as automatic brightness adjustment and "original color" to not work properly.
Apple says that Mac laptops have a camera indicator design to let you know when the camera is turned on.
The FaceTime HD camera built into the Mac computer is designed to pay attention to your privacy, and the camera indicator used will emit a green light when the camera is activated, so you can always keep the camera on.
In fact, some users really caused the MacBook screen to malfunction because of the WebCam Cover. Since users sometimes close their MacBook without having a WebCam Cover, the screen may be damaged.
