Everything returns. There are brand icons and symbols that seem to disappear and eventually come back. Like the glass bottle of Coca-Cola that seemed devastated by cans, or Converse sneakers.
Apple in 2016 capriciously loaded the initial sound emitted by Macs, and that would not be heard again. It seems that now it can be recovered with a simple command in Terminal.
Sometimes large companies make decisions that are somewhat strange and incomprehensible to users. The sound of the bell heard when starting a Mac was a central part of Apple's marketing for many years. An iconic sound associated with the bitten apple logo.
An update of macOS in 2016 eliminated this bell by the root, without leaving the possibility for the user to choose to listen to it or not, which would have been the most logical. Now a user has figured out how to reactivate it, and has shared his achievement on Twitter.

How to activate the initial bell on your Mac
- Open the Launchpad
- Opens Others
- Opens Port
- Type sudo nvram StartupMute =% 00 and hit enter
If you want to mute it again after activating it, enter the same command changing only 00 to 01. If you activate it and don't hear it, don't worry. You just haven't been lucky. this trick seems to be that it doesn't work on all Macs, it depends on the model.
Another Terminal command was discovered long ago shortly after the bell's removal in 2016 that restored sound, but was removed again in a later update. We do not know if this new return of the initial sound is intentional by the company, or will be removed again in a future update.
The truth is that I do not know why Apple decided to eliminate this sound. Perhaps they thought it annoyed users every time they turned on their computer. It would have cost nothing to activate or silence it at will from System Preferences.
You forgot to mention that the system asks you for your password when entering the command, because the action you are trying to execute is at the "superuser" level, which is what the 'sudo' command implies…. otherwise I tried it and it worked without problems !!!
