Disable boot on power source and boot on lid open by running this on terminal:

sudo nvram AutoBoot=%00


Enable it again by running

sudo nvram AutoBoot=%03



-----
Feature removed by apple on latest firmware, doesn't work anymore.
Bonus: Boot chime control
sudo nvram BootAudio=%00
sudo nvram BootAudio=%01


More about the boot audio thing later.

You are a champ! I don't even own the new MBP but this will cheer up a lot of folks. Nice work.

I was wondering when I first read about this - was it only disabled on power on, but still occured on a restart?

Short question for clarification: is my interpretation correct that the first of these commands disables the boot chime, while the second enables it?

I have two questions:
  1. Could I enable AutoBoot on my older Mac?
  2. Can I have both the chime and AutoBoot on my new Mac?

I tried the audio commands and no "bong". Are we sure this works?

What’s the build number of macOS you’re running?

2. Yes.

Oh man you spoiled a headline news with virtually all IT tech website - they are sooooo lame to not figure it out.

You are champ!

Kudos or should I say kiitos!

You brought back, and I quote: "iconic Mac startup chime" - haters will be sooo disappointed.

:p:D:p:D
