The Auto Boot feature powers on your laptop as soon as you open the lid, so it should be disabled before undertaking certain repairs. Auto Boot can be found on 2016 (and newer) MacBook Pros and 2017 (and newer) 12" Retina MacBooks.

This guide will walk you through the process of disabling Auto Boot, and then re-enabling it when your repair is complete.

Note: Disabling Auto Boot may not work on Apple’s newer ARM-based M1 MacBook Pro or MacBook Air, released in late 2020. At this time, we don’t know any procedure for disabling Auto Boot on devices equipped with Big Sur v11.1 or later.

  1. Power on your Mac and launch Terminal. To launch Terminal, you can either use Spotlight Search or navigate to Applications / Utilities in Finder and double click the Terminal icon.

    Hi. This does not work on 2018 13” MacBook Pro with Touch Bar. I did exactly this to disable auto boot. But when I check by using nvram -p it says: auto-boot true. Am I doing something incorrectly? I did everything step by step. Copied and pasted the sudo command, pressed enter and then entered my password. I have Big Sur 11.1 installed. Is there any other way since I need to replace the screen. Thank you. Adrian

    I have a new MacBook pro 13 MI chip and tried doing this on my computer because I was very annoyed. I followed these steps and it did not work. I still have not found a solution. Are there any suggestions?

    Good question! These instructions are for Intel-based machines—I don’t know of any solution for the newer ARM-based (M1) MacBooks. If we learn how to do it, we’ll update the instructions.

    Ciao, provando la seguente procedura su MacBook Air 2020 (Intel) non accade nulla una volta inserita la password.

    Ho provato a spegnere per vedere se le modifiche avevano effetto ma niente, il Mac si avvia premendo tasti e aprendo il display.

    Solo in alcune occasioni invece mi viene mostrata la percentuale della batteria a schermo nero.

    Quando fa cosi significa che è stato disattivato l’avvio automatico?

    grazie, spero mi possiate aiutare.

    Ive applied this to a MBP 15” A1707 and it worked. Now when i open the laptop display a battery level appears for a few seconds. I’d rather see that than have the mac auto start ans so i will not be re-enabling auto-boot function

    I tried this on a USA MacBook Pro 2018 (A1989 EMC 3214), but it did not work.

    AutoBoot remains on. What now?

  3. You can now safely power down your Mac and remove the bottom case, without it accidentally powering on.
    • You can now safely power down your Mac and remove the bottom case, without it accidentally powering on.

    • Remember, you must still disconnect the battery before servicing internal components.

    One slight problem I found with the Mid 2018 MacBook Pro 13-inch: It still powers on if you accidentally touch the touchpad or inadvertently press a key. Is there a way to disable this behaviour temporarily whilst carrying out repairs?

    On top of that, I couldn’t find a comprehensive 2018 teardown guide, so wasn’t even sure which one was the battery connector. I disconnected what I thought was the battery, but viewing some other videos, it appears I didn’t have the battery disconnected whilst replacing the screen! Out of sheer luck, nothing got fried and the replacement screen works fine.

Hi I have done this and it worked in disabaling the auto boot feature but it now displays the battery symbol with the percentage charge! Is there a way to disable the battery symbol from appearing?

Kirk Davis - Contestar

This only prevents from turning on when lid is opened, but pressing any key it turns on again… very annoying
