updating auto-boot option to 'false' broke my macbook

My macbook (16" M2 Max) is no longer able to boot after running `sudo nvram auto-boot=false`. Now when pressing the power button (or opening the lid, for that matter), a message is displayed directing me to support.apple.com/mac/restore

My question is:

  • Why is this feature so locked-down as to be completely inconfigurable?
  • Why does an nvram setting from previous generations of macbook being changed cause the machine to be effectively bricked when modifying this setting to `false`?


For context, this was done in an attempt to disable the auto-boot upon lid open feature, which currently interferes with the practice of opening the lid to see if the computer is on.

MacBook Pro 16″, macOS 14.5

For those who have done this and need a solution to revert the change:

  • power off the macbook
  • hold down the power button until startup options are loaded
  • boot using the macbook's disk
  • hopefully this succeeds and allows you to login
  • open a terminal and run `sudo nvram auto-boot=true`


This doesn't resolve the root cause of the issue - a lack of user configurability or documentation thereof
