How to Enable the Mac Startup Chime on New Macs

Mr. Macintosh:

sudo nvram StartupMute=%00

Reboot.

I have literally rebooted 5 MacBook Pros multiple times just to hear that classic sound. I could not be more happy!

Hell yeah I enabled this. No idea why Apple did away with this chime.

(Use “01” in place of “00” to turn the chime off.)
