How to completely turn off the boot sound on Mac

Mac users know that every time they turn on their phone, there will be a "duang" boot sound, and sometimes the sound is loud and startling.

If you want to temporarily disable this boot sound, a simple way is to keep holding down the mute key (F10) on the keyboard when you turn on the phone, but this method is to treat the symptoms rather than the root cause.

1. Open "Applications", open "Utilities", find and open the [Terminal] program, and then enter the following command and press enter (note, don't copy more spaces when copying.)

2. After that, you will be prompted to enter the password, enter the user password, and press Enter.

This way, when you start your Mac again, it will be completely silent.

Note: You can't see it when you enter the password, you can't see it like you can enter the password, just enter it, press enter after entering.

3. If you want to restore the normal boot stiffness, just enter the following command in the terminal again: sudo nvram -d systemaudiovolume

How to turn off the mac boot sound.

1. If you need to temporarily turn off the Apple computer boot sound, you can press and hold the F10 mute button on the keyboard after booting.

2. If you need to turn off the Apple computer boot sound for a long time, you can enter ** in the terminal**, and if you need to recover, you can re-enter sudo nvram -d systemaudiovolume**.

Note: On a dedicated keyboard for Windows PCs, use the Alt key instead of the Option key and the Windows flag key instead of the Command key.

Some keys on the Apple keyboard have special symbols and features, such as display brightness, keyboard brightness, Mission Control, and more. If you don't have these features on your keyboard, you may be able to implement some of them by creating your own keyboard shortcuts. To use these keys as F1, F2, F3, or other standard function keys, use them in combination with the Fn key.

There are several types of operations:

1.Before shutting down or restarting, turn the volume down to the lowest so that the next time you turn it on, there will be no boot sound. But remember to adjust the volume every time.

2.If you're using Apple's keyboard, when your Mac has just turned on, quickly press and hold the F10 key until the gray apples appear, so that your Mac doesn't make a boot sound.

3.You can use a scripted method to turn off the sound when the user logs out, and unmute it when the user logs in, so that the boot sound disappears.

1. Open the Finder on the left, then click on the application here to find the function in the frame;

2. Then click on the top utility, and then a new page will pop up, and then click on the terminal option in the pop-up box;

3. Then enter the command in the terminal and press Enter, enter the administrator password. If nothing is displayed during the input process, the administrator password is the password set for the first time the computer is turned on;

4. Then after entering, there is no display, and this [$] is displayed, then it means that the setting is successful, and the next time you turn on the phone, the system sound is completely turned off.
