Apple Advises Against MacBook Camera Covers Due To Display Cracking (appleinsider.com) 126

Apple, in a new support document, is warning users against closing their MacBook lids with a cover over the camera. From a report: Placing a cover, sticker or tape over a laptop camera is a practice adopted by some privacy- and security-conscious individuals to protect against webcam hijacking. Now, however, Apple is explicitly advising against the tactic. In a support document published earlier in July, Apple urges users not to close their MacBook Pro or MacBook Air lids if there's a camera cover installed on it. "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," Apple notes. The support document also outlines some of the privacy and security functions of the camera, including the green indicator light that lets users know when the camera is active and the camera permission settings introduced in macOS Mojave.

      That's what they had on the original iSight FireWire camera. They had a mechanical shutter that you operated by turning. When you opened it, it'd trigger an event to open iChat AV; FaceTime's predecessor. When you closed it, it'd turn off the camera and microphone circuit along with closing the shutter in front of the lens. It was a quite expensive camera though, so the built in ones resembling what we have now came next and were the first popular ones, since there was no opt out choice either.

      As a reply has already pointed out, that's wrong. But your assertion is also wrong—I very often expect tight tolerances out of my equipment and electronics. I want a paper-thin gap when it's feasible for one to exist without compromising the functionality of the product. Go look at the panel gaps on a Japanese car—they're all as small as they can be with very little deviation. Now look at cars made by virtually anyone else—the tolerances are sloppy and ugly.

      Tight tolerances are often a sign of quality engineering. Being able to fit 2mm of plastic between the lid and the case would be a sign of shit build quality.

    The support document also outlines some of the privacy and security functions of the camera, including the green indicator light that lets users know when the camera is active

    That's backwards. If the light burns out or somehow fails, the camera can be on and you'll assume it's off because you've been trained by the indicator to think that light off = camera off. You won't realize the indicator has failed until you deliberately turn the camera on and notice the light doesn't turn on.

    The most important indicator is one that tells you that the camera is off, not on. Lenovo did this right. The built-in cover on my Thinkpad's camera [youtu.be] shows red when it's closed. So whenever I see it's red, I know the camera is covered and I'm protected. If it fails (say the cover breaks off and falls inside the bezel), I know the camera is uncovered because it's no longer red. It fails safe, rather than fails dangerous.

    If you want, you can add another indicator to tell you the camera is on. But to protect against failures, the most important indicator is one that tells you the camera is off, so you can assume the camera is active if you don't see that indicator.

    • The other big problem with the light is that it comes on with the camera when it starts recording. So that means that if you happen to see that it's illuminated, it may already be too late.

  • by Anonymous Coward
    the light is not a substitute. first because it's a software-controlled feature and can be overridden. second because the point of the cover is to make sure the camera isn't turned on. for example if you are taking a conference call on the toilet. you want to be absolutely sure the software doesn't decide to turn the camera on.

  • Funnily enough, most users started using the covers because they were afraid of cracking.
