Everyone who has used the above computer knows that there is a bang sound when booting. This sound can easily scare others. Especially when the computer is turned on at night, how do you completely cancel this or turn off the boot harmony? After groping through the editor, I finally found a way to shut down completely. The following is introduced to everyone.
1. Open the finder on the left, and then click the application here, which is the function on the sidebar.
2. Then click on the utility at the top and click on the terminal here.
3. Then type the command in the terminal: [ sudo nvram SystemAudioVolume =% 00 ], then press Enter, and enter the administrator password. There is nothing displayed during the input process, this needs attention. The administrator password is the password set for the first time when the computer is turned on.
4. After entering, there is no display, this [$] is displayed, then the setting is successful. There will be no sound the next time you turn it on.
5. If you want to restore the sound of booting, then enter the command: [ sudo nvram -d SystemAudioVolume ], press Enter, and enter the administrator password again. If your computer resets [NVRAM], then this function is invalid, you must re-enter the command to do it.
