On lid open Macbook Pro 2016 boots automatically - after turning off I need to juggle 10 seconds with the touch id power button to boot

This is a side-effect of the implementation. Setting the AutoBoot NVRAM variable doesn't actually prevent the machine from booting.

  • The machine will still boot automatically when the lid is opened, or on the first power button press, but will only boot to a page with a battery icon.
  • Until the machine shuts down again (by itself after a little while, or by the power button again), the power button won't work to turn the machine on.
  • Once the machine is off, you can use the power button again, at which point the machine boots normally.
