If you ask someone why they use a webcam cover, chances are it’s for security reasons. However, Apple now says you must remove these covers or face the consequences.
Apple says you shouldn't use a webcam cover and we agree: here's why
A good seal: According to an Apple support page, a webcam cover prevents the MacBook from closing completely because they are “designed to very tight tolerances.” Continuing to use a cover could damage the screen.
Going coverless: Instead of using a cover, Apple suggests relying on the camera indicator light, which glows green when the camera is active. No green light means the camera is not active and your activities are safe from prying eyes. Another tip is to control which apps have access to the camera, which can be done through System Preferences.
“We design Apple products to protect your privacy and give you control over your information,” Apple says. “Our products and features incorporate innovative privacy technologies and techniques designed to minimize how much of your data we — or anyone else — can access.”
