    Perform a hard system restart

    Click the Apple menu and select Restart. If the system is unresponsive, hold the power button or Touch ID sensor until the display turns black, wait five seconds, and power the device back on.

    Note: A hard reset forces the hardware drivers to reinitialize upon startup.

    Confirm physical hardware integrity

    Ensure no physical obstructions cover the camera lens. Check for third-party privacy covers or security software that explicitly disables camera hardware input at the kernel level.

    Note: Some enterprise security profiles block the camera for compliance reasons.
