If you suspect that hackers are spying on as you chow down on your deep-dish Dominos and watch 365 DNI for the fifth time, you may want to rethink that post-it note you've been covering your Mac camera with.
Whether you own a MacBook, MacBook Air, or MacBook Pro, the simple act of closing down your Apple laptop while a camera cover is in place can interfere with features like light display and automatic brightness.
MacBooks are designed with privacy in mind, and the little indicator light glows green when the camera is active - meaning you'll always know when the camera is in action.
One reason for this is that the closing mechanism of your computer is a fine-tune design designed to "very tight tolerances" meaning that an extra layer obstructing the camera has the potential to cause display damage.
Added to that, there are a bunch of features that a makeshift camera cover can affect, including the ambient light sensor, auto-brightness settings, and Apple retina display True Tone technology.
The post reads: "If you close your Mac notebook with a camera cover installed, you might damage your display because the clearance between the display and keyboard is designed to very tight tolerances.
"Covering the built-in camera might also interfere with the ambient light sensor and prevent features like automatic brightness and True Tone from working.
It continues: "As an alternative to a camera cover, use the camera indicator light to determine if your camera is active, and decide which apps can use your camera in System Preferences."
Apple go on to advise that if you're someone who works in an "environment [that] requires a camera cover at all times" then it's best to use something slimline and non-sticky that won't leave an adhesive residue.
Apple say: "Make sure the camera cover is not thicker than an average piece of printer paper (0.1mm)" in order to avoid damaging the display.
If the worst happens and your camera is damaged, you should be covered by AppleCare+ Insurance.
