I have the late 2015 (15 inch) MacBook Pro. By default it turns on when laptop lid is open. This is not good for me, sometimes I open the lid on weak battery to make sure it's not turned on, so I wanted to make sure it's off. And then it just wants to boot up, imagine.
(Side note - I don't use sleep function, because it eats up an unoptimally lot of swap and compressed memory (which also cannot be changed since 10.9, see Can I turn off swap and/or memory compression on macOS 10.12, Sierra? ), I use nosleep extension to just lock the screen on lid close when on AC, or on battery for short)
Thankfully there is a leaked (not documented) bash command to change this in terminal:
sudo nvram AutoBoot=%00
But then if the machine is turned off, the power button behaves strangely:
- On first press (no matter long or short) the battery status will show with a percentage.
- Until this screen and this mode goes off (few seconds), everything you do with the Touch ID power button is ignored.
- Then you can press the Touch ID button long to power on, when you release it, Apple logo shows up so the system is booting finally.
So I'm happy the startup tune is off now, but instead you need to morse a startup tune through the power button to power on your MacBook Pro ;)
Is there a tweak to make this work as expected for an old physical power button to turn on properly in the old easy way?
