You may think of it to be pretty obvious, but Apple literally just published a support page warning against closing the laptop when the camera cover is in place. There's no need to make fun of apple for this. They’ve said that it could result in a cracked display because “the clearance between the display and keyboard is designed to very tight tolerances.”

You may know about the plastic covers that have a sliding mechanism. Well, do you know that they’re bad news for your laptops? Considering Apple’s repairs are costly, it’s better to get something that isn’t cheap.

Hence, as a recommendation, Apple has suggested the green LED for the camera on MacBook Pro and MacBook Air. “The camera is engineered so that it can’t activate without the camera indicator light also turning on.”

Apple understands that some employees are mandated by their employers to use the camera covers, so in that case, it has advised to remove it before closing the laptop.

Furthermore, there are cases when the screen of MacBook Pro has broken even when a very light pressure is applied to close the laptop. If you don’t trust the light, then you should instead, go for a strip of tape instead of a stick-on cover – it’s definitely safer!
