A tight seal: According to an Apple support page, a webcam cover prevents the MacBook from closing completely, as they’re “designed to very tight tolerances.” Continuing to use a cover could result in a damaged display. Going coverless: Rather than using a cover, Apple suggests relying on the camera indicator light, which glows green when the camera is active. No green light means no active camera and your activities are safe from prying eyes. Another tip is to control which apps have camera access, which can be done through the System Preferences. “We design Apple products to protect your privacy and give you control over your information,” says Apple. “Our products and features include innovative privacy technologies and techniques designed to minimize how much of your data we—or anyone else—can access.” Camera shy: If you must use a camera cover, Apple recommends it be no thicker than 0.1mm and should leave no adhesive residue. If it is thicker than 0.1mm, remove the cover before closing your MacBook. Bottom line: It’s unlikely camera covers are going away anytime soon, but the very least you could do is make sure your camera cover isn’t thick enough to leave a gap when you close the laptop for the day. No one wants to get their screen repaired, or their MacBook replaced, because of a camera cover and (completely reasonable) webcam anxieties. Via: The Verge
