Is there a way to lower the startup sound on a MacBook M1 Pro? I have adjusted the slide bar but its still not a low as I had on my 2014 Macbook Pro.

Hey there boxerdog62,

If you're tried turning off the startup sound using the link from the related article, then try adjusting the system volume and test to see if that helps with the sound during startup.

1. On your Mac, choose Apple menu  > System Settings, then click Sound  in the sidebar. (You may need to scroll down.)

2. Click Output on the right, then select the device you want to use in the list of sound output devices. 

All sound output devices available to your Mac are listed, including the computer’s internal speakers, devices plugged into your computer’s sound port (), USB speakers, and AirPlay devices.

For any device plugged into the computer’s sound port, choose Headphones.

3. Do any of the following to adjust your sound output settings:

• Adjust the volume: Drag the Output volume slider.

If you have Sound in the menu bar, you can turn the volume up or down from anywhere.

To set a volume for alert sounds, drag the Alert volume slider in Sound Effects. The alert volume is relative to your computer’s volume, so if you lower the computer’s volume, alert sounds also play more quietly.

• Stop sound output: Select the Mute checkbox.

• Adjust the balance: Drag the Balance slider.

Change the sound output settings on Mac

Take care!
