How to Turn on the Classic Mac Startup Beep
Donnning. Classic Mac Ringtone is a great way to let yourself know that your Mac is booting up after shutting down or restarting. But if I’m right, this friendly buzz has gone missing for most new Macs over the years . (I only have a MacBook Pro, and I can confirm that booting up my MacBook has been boring and quiet for as long as I can remember.)
If you’re missing the classic Mac boot sound – ah, nostalgia – you can get it back in less time than your Mac will likely need to boot, period. I have not tested this trick on any other Macs and I believe it only works if your Mac has a T1 or T2 chip inside. However, this is such a short process that it doesn’t hurt to give it a try.
First, open your Terminal. Once downloaded, enter the following:
sudo nvram StartupMute=%00
Press Enter, enter your Mac password, unmute or turn up your Mac volume to a reasonable level and restart your laptop or desktop. You should now hear the old familiar “donnnnng” sound when booting your system. If not, you’re out of luck.
If you ever get tired of the startup sound, you can simply reset PRAM to turn it off, or go back to Terminal and enter the following:
sudo nvram StartupMute=%01
