Macbook Startup Sound

Disclosure: MacBook Pro helped me in the computer world since December 2012. I bought it myself around San Francisco and loved its ANSI keyboard (because it is very good to touchtype DVORAK on it).

This year I bought a used MacBook Air from its first owner, again a model bought originally in the U.S. This one is Linux-only since the beginning and it works reliably well.

Here is what I found at the Arch Linux wiki regarding how to mute the startup chime and it worked. Thanks!
