2016 MacBook Pro: Enabling the Startup Chime... does not work

Apple removed the startup chime by default for the 2016 MacBook Pro, but it can be restored. Thanks to reader Jewels Davies for passing along this nvram fix.

UPDATE: I tried the solution below immediately after writing this post... the wrong order of course, but the machine was running a test at the time and could not be interrupted. This solution just does not work on my MacBook Pro. The volume is at maximum and not muted and there is no sound upon restart. A dozen Mac web sites apparently all copy each other and never bother to test if a claimed fix works.

Enabling the startup chime

Does not work.

The commands shown should be entered in a Terminal window.

To enable the startup chime:

sudo nvram BootAudio=%01

To disable the startup chime (silence):

sudo nvram BootAudio=%00

I too cannot get Startup chime re-enabled on Macbook Pro 2016. Did you find an alternative solution?

MPG: nothing yet.

I can confirm this doesn't work! Tried a number of times, no start up tone.

Another issue; can't boot into single user mode. Tried of course Command S, then just S, then Control S; no go. Weird.

DIGLLOYD: so far, no one has stated that it ddoes work.

Auto boot

Not tested or verifed as yet.

Auto-boot means that when the lid of the MBP is opened, it starts up. Given the confusing lack of a power-on button, it is probably best to leave auto-boot enabled.

Disable auto boot:

sudo nvram AutoBoot=%00

Enable auto boot (boots when lid is opened)

sudo nvram AutoBoot=%01

I’ve got a Late 2016 15” MacBook Pro and can confirm that enabling the startup chime does not work, however disabling auto boot does. Without auto boot enabled, a large battery status icon is shown in the centre of the display.

Kind of cool, it helps now that there’s no way to see your battery status without booting up your Mac!

MPG: nice feature.
