The Happy Mac sound used to indicate that the Macintosh computer has successfully run the usual diagnostics and the system is running in normal conditions. Whereas, the Sad Mac or Chimes of death used to indicate a problem in the hardware. All the old versions earlier used to have different chimes. After the release of MacBook Pro 2016, these startup sounds were removed for Macintosh computers, except for MacBook Air 2017.

There can be many reasons that you don’t want the startup sound every time you turn on your computer. Maybe you work late at night and don’t want the sound to disturb your family’s sleep. Or you are attending a meeting and you don’t want everyone to notice you when you turn on your computer. Or any other reason.

If you have the earlier version of Mac and you don’t want the startup sound, every time you Turn On your Mac, then we have some easy tricks for you that you can use. You can either Mute it temporarily or permanently with these hacks.

Third Method

If turning down the volume every time before Shutting down your MacBook is not the thing for you, or you forget to do so every time then we have another hack for you. This is known as the Auto Mute app. After installing this app you don’t need to worry about turning down your MacBook volume before turning it off. Auto Mute will automatically run and turn the volume down when you turn off your MacBook, resulting in a quiet and no sound when you turn on your MacBook next time. But this is a third party app. You can choose among any of the Auto Mute apps from the app store and try it if you wish. These apps will ensure that the sound is automatically muted every time you turn off or turn off your Macbook.

If you were not looking for a temporary fix like this one, you can continue to the next step to permanently disable or mute the startup sound.
