Re: Don't close your MacBook with a cover over the camera

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. Doesn't this sound like an engineering oversight and not a user error? Why are camera covers not just part of the design? My phone camera physically retracts when not in use.

Your phone camera sounds like an engineering oversight.

As a former one plus 7 pro owner, I agree with this sentiment.

There's a reason Zukerberg's laptop has its mic and camera tapped up. It doesn't matter what device you use unless there's a physical switch to disconnect it'll never be safe. Software can ALWAYS have zero days, just because it hasn't been exploited yet doesn't mean it can't be.

But can't you specifically wire the indicator light to always be lit if the camera has power? I don't see Apple claiming they've done that but a correct design would make the indicator light work that way and be related to software at all. Meaning you could only disable the indicator light by physically modifying the device.

This is the only correct design, yet almost nobody does this. One of the challenges is verifying that this was done correctly.

You may be able to verify a design like this once with a teardown, but it's impractical to verify your particular device, and next to impossible to re-verify this every time you leave your laptop unattended.

People are suggesting just using tape, but the issue is when you want to un-cover it frequently (which is probably more common now than a few months ago). For a couple dollars you can get a thin, nice-looking little plastic cover that you can actually slide out of the way when you need to use it. Most of these are thin enough not to be a problem, but they vary, and even the really thin ones usually don't quite let yo…

Black electrical tape actually retains stickiness surprisingly well, and it peels off easily.

even then there probably should be some minimum "flash" time in that if it turns on and off faster than the LED lights up or human eyes can see then it may still take images faster than we can register?

EDIT: a commenter below said

"Macs newer than 4 or so years also have a feature that forces the LED to stay lit for at least 3 seconds after it has been turned on to prevent the single-frame-grab attack."

> Why are camera covers not just part of the design? I guess Apple are going to say that they'd rather focus on the security of the OS and computer to prevent unauthorised software from being able to access the camera than on a mostly cosmetic doodad.

A simple built-in camera cover is not a cosmetic doodad. And physical covers cannot be remotely hacked, unlike the active camera light which has been overridden multiple times.

If we're talking about focusing on security, then the choice should be clear.

Nice try there Mr.CIA (wink-wink)...

It's connected to the damn circuit! You can't power up the webcam without powering up the light any more than you can make the camera see through a piece of electrical tape.

What makes you feel that way?

I enjoy the peace of mind and lack of a notch on my screen. It's designed and advertised as a feature, not an oversight.

Yeah, people who don't understand how hardware works.
