Apple had removed the chime on MacBook Startup for a few years, after the launch of the Newer Generation MacBooks.
The Startup Chime was a very famous sound and was loved by the Mac users until Apple decided to remove it.
However, if you’ve been missing out on that, I have good news for you! It has just come back on the Newer MacBooks.
Let us see how we can bring back the MacBook Startup Chime Sound on your New MacBook.[UPDATE]: Apple has brought back the Startup Sound (or Chime) on the macOS Big Sur update. You can either upgrade to macOS Big Sur to get the iconic Mac Startup Chime or if you don’t want to upgrade, you can follow this tutorial.
There are two ways you can enable the MacBook startup Chime Sound.
Launch Terminal on your Mac. Go to Spotlight search and type in Terminal to fire up your Mac’s terminal.
Once the terminal is open, copy paste the following command and press Enter.
sudo nvram StartupMute=%00
To Disable the Startup Chime Sound on your MacBook, simply run this command on the terminal:
sudo nvram StartupMute=%01
2. Using an App
If you don’t want to fiddle around with the terminal, you can simply use this application by DosDude1 and enable the Chime for the Mac.
It is a very simple and lightweight app for enabling the Chime on the Mac. It is named “ChimeEnabler”.
