Be careful. My Macbook Pro cooked it's display twice. Some program made it not go to sleep when I closed the lid, I put it in my backpack, and it overheated the display so much that I had yellow-brownish spots (which followed gravity over time). No way to check if it's sleeping when the lid is closed, because reasons...

I really miss the "snoring" light that Macbooks used to have, though more to tell if the computer is actually waking up.

I really don't get why they left the light off them. It's not something that takes any space at all and they can even make it invisible when off with their micro holes like they did with the old Bluetooth keyboard.

Sometimes it seems Apple is just minimalist for the sake of it. Because this is really a useful feature.

I doubt lasering those holes is particularly cheap, i.e. likely much (much) more than the cost of a big hole with an LED.

But I do very much like them, and would happily pay a bit to get it back.

They could manage it in a $80 keyboard when that tech was new and probably more expensive, I'd think they could do it in a $1500 laptop :)

And a hole with a plastic insert would be fine for me too. It wouldn't be as minimalist but not doing it at all is much worse IMO.

Membrane keyboards are so incredibly common and simple to make that I'd be willing to bet they make dramatically more profit on that keyboard than on a $1500 laptop (proportional to price). Even after accounting for all the wasted R&D and refunds and repairs spent denying problems with their butterfly mechanism.

So kinda yes... but also kinda no, I don't think that really supports a claim that it's cheap enough to do everywhere.

But yeah, I'd totally be fine with an LED glued into a hole. The indicator is the important part, and it's a shame that it's gone.

I wouldn't be surprised if they feel like macbooks are so reliable that sort of feedback isn't even necessary

I always assumed those were the result of my cycling backpack putting too much pressure on the screen. It's basically bow-like structure to keep the bag off my back.

I do have my MacBooks cooking themselves in my backpack every so often too.

Basically, every MacBook's I had in the past > 10 years ended with that issue.

Mystery solved!

I can confirm that this is the issue. I have little white spots on the display, and they appear during my motorcycle trips, when my luggage is pushing against the display. I got a fresh one from the latest trip. Armoured cases are not nearly as armoured as they should be.

What’s the name of the backpack btw? Been looking for something like this

We have a few users that leave clamshell mode while working at home and the past year never opened their laptops. Same thing. Permanent heat stain on the display in the form of the keyboard. Granted that's more than just sleeping issues, but it's definitely something that happens.

I once had told Caffeine not to sleep my 2014 MBPr when the lid was shut and later put it in my backpack.

Why the frak doesn’t the laptop have an over temp shutdown feature? iPhones so, trying leaving one in the sun for a bit.

Caffeine shouldn't prevent it from sleeping anymore anymore unless you have an HDMI plugged in it.

Yes and Macs have worked like that since the PPC days. Display closed + no external display connected = sleep. Removing said display will also make it sleep.

I guess it's a bug or some monitoring service that crashed.

Perhaps it was Amphetamine with the relevant setting to prevent sleep with built-in display closed.

Any fullscreen apps using the GPU will prevent a MacBook from sleeping when the lid is closed. Games, YouTube, even some GPU-heavy apps can prevent it from sleeping.

I’ve had this issue with my work Mac not sleeping: I’ve always hypothesized it’s something to do with the provisioning of the machine, because it’s the only Mac I’ve ever had this problem with.

This happened to my iPhone 1 too. Caused a really ugly burn in the display :'(

Of course iOS wasn't as stable as it is now.. I don't think this will still happen.

Is there a way to find out what app is guilty?
