Webcam covers may protect privacy but risk damaging MacBook displays, Apple warns. The lid-to-keyboard gap is engineered with millimeter precision; adding even a thin plastic cover concentrates pressure on the screen, potentially causing cracks, permanent marks, or display failure. Newer models with the notch design have virtually no bezel for a cover to attach. Apple recommends only paper-thin covers (~0.1mm) — and notes such damage voids the warranty.
Safer privacy alternatives exist. Every MacBook has a hardware-tied green LED that lights when the camera is active; the MacBook Neo shows an on-screen green dot. macOS also requires apps to request camera permission. Users can audit and revoke access in System Settings → Privacy & Security → Camera. If the indicator lights unexpectedly, review those settings immediately.
Engadget's Filipe Espósito emphasizes that physical covers are largely unnecessary given these built-in safeguards.
