Now if only there were a fix for MacBooks turning external displays on while they’re asleep (even with Power Nap disabled) and connected via thunderbolt…

This happened all the time when I ran a Dell monitor in my setup. I now have 2x Apple Studio displays and this hasn’t happened once in over a year.
 
I can see the need for wanting to open or plug in a MacBook without it turning on, but I think it's enough of an edge case that people who want it probably are going to be comfortable opening up Terminal and putting in a few commands. It's like 60 seconds work.

Myself, 95% of the time it's on but sleeping, even for a week at a time. I just find it more convenient to have all my apps and windows ready to roll as soon as I wake it up.
 


Apple designed Macs with Apple silicon chips to automatically turn on and start up when the Mac's lid is opened or when the Mac is connected to power, but there is a workaround in macOS Sequoia if you don't like this behavior.

In a new support document, Apple provided separate instructions on how to prevent an Apple silicon Mac from turning on when the lid is opened or when it's connected to power. Both processes require the Terminal app. Apple's instructions:

1. Make sure that your Mac laptop with Apple silicon is using macOS Sequoia or later.
2. Open the Terminal app, which is in the Utilities folder of your Applications folder.
3. Type one of these commands in Terminal, then press Return:
- To prevent startup when opening the lid or connecting to power: sudo nvram BootPreference=%00
- To prevent startup only when opening the lid: sudo nvram BootPreference=%01
- To prevent startup only when connecting to power: sudo nvram BootPreference=%02
4. Type your administrator password when prompted (Terminal doesn't show the password as it's typed), then press Return.

If you use these commands to change your Mac's behavior and want to undo it, you can open up Terminal and enter sudo nvram -d BootPreference.

Great this option which we've had in the past is back however it still has some shortcomings. Like others have mentioned why can't they be a little more civilized and just add an option under preferences? Also the stupid thing still powers on if you touch the touchpad. My MacBook Pro has a power button and I just want the stupid thing to power on when I press the power button is that too much to ask for a $3K laptop? I think not! It's about me and what I want I should be able to set it so it works my way. No I don't want to install some stupid app so that I can clean my computer and prevent the computer from powering on accidentally when the touchpad is pressed. Never ending saga on a simple issue!

Yeeeeah, use cases like "what if I want to use my MacBook as a doorstop in a room full of sleeping tigers" are not, in my book, sufficient reason for stuffing another toggle switch into System Preferences. It's times like these that I find myself missing Jobs' unapologetic "we designed it right, it's you who is wrong" approach... because a lot of the time, he was correct.
True. I feel like some of it stems from treating laptops as pieces from a museum.
 
I would like to be able to switch on my MacBook (m1max16") with the lid closed.
I have tried powering it via USB-C from one of the external displays, but this has ruined the display, perhaps because it only supplies 90W.
 
is there a way to keep the lid close but still stream to Apple TV?
I believe there’s a free program called Amphetamine that will keep the laptop on with the lid closed. I use it with Astropad Studio to turn my MBP into a touch screen MBP with the help of a stacked IPad.
 
I suspect the millions of comments of 'If I open my laptop, I want to use it!' adequately explain to the other million comments saying 'Why is this a terminal command and not a GUI setting?!'

It's an uncommon use case. There are many, many uncommon use cases that can be configured from the command line and not the GUI.

Incidentally, you don't have to 'learn to code' to use these options. If you know how to open an application, if you know how to copy and paste, then you also know how to enter a command from Apple's website into the terminal.

If only there was an option to keep the lid open but use 2 external displays on the Macbook Air M3 (for cooling purposes).
There is a workaround:

- While your monitors are plugged in, go to Screen settings
- Select one of your external monitors
- Choose to recopy the external display to MacBook’s screen
- Dim MacBook’s screen to 0 brightness

Done!

Jobs should have never made Cook CEO. Jobs should have made Scott Forstall CEO.

Forstall was responsible for leading the development of Mac OS X (and iOS). If Clueless Cook hadn't fired Forstall, Forstall would've still been at Apple. The absurd situation of users having to use a command prompt in 2025 for basic functionality would've never happened if Forstall was still in charge of Mac OS.

Not sure Forstall would have been a good CEO, but he would indeed have been a great leader for everything related to UI-UX.

Concerning Cook, optimizing operations was probably a great move in 2011 (Cook has its own merits), but now, he should leave his position to somebody having an actual vision.

But no, Scott's not there, dropping his skeuomorphic design for the 'flat' interface has improved performance of the OS.
What are you talking about? Quite the opposite happened. With iOS 7 and many versions after that older devices were very slow. Even the newest devices were dropping frames. It didn’t helped the performance at all. And it looked and still looks amateur.

Because most people aren’t gonna use it, and it’s always a balance when you put in more preference settings, since the UI will get cluttered.
Well, they should work harder on that de-cluttering of the UI. With every new software version the UI gets worse. As an example look at the horrible new settings app on Mac.

For everyone wondering why they don't just make it a preference, it's because if they spent time on that, people would complain that they were wasting there time on implementing things that "nobody uses" instead of other things. You can't please everyone. Even if it it's something that takes 5 minutes to implement. This is why we have 3rd party power management apps like Caffeine.
 
My first reaction: "I'm gonna do this!"

Three seconds later: "So one less way to wake my Mac, increasing the odds in a weird situation of bricking it."

Uh... Thanks anyway.
 
What's the use case for opening the laptop and not wanting it on?
I often set up my workstation in the morning and open the laptop but have o run to a meeting, so I don’t want it on just yet.
Other scenario: I want to clean the screen & keyboard, but don’t need it on.
 
Like many others here, though, I’d *really* like to turn off the “power up when any key is typed” option.
I have oily fingers so like to clean my keyboard and trackpad often. The automatic startup is a bone of contention for this loyal (32 years and counting) Mac user.
