Annoying startup chime sound is back after security update 2020-001!

[macpot]

Hey guys,

I have a Macbook Pro 2020 with Catalina 10.15.7, and after the security update 2020-001, the startup Chime Sound is back with no option (in System Preferences > Audio) to disable it!

If any of you guys know a way to disable it, or lower the volume, please let me know!

I remember that a few years ago when there was a Chime sound, if I muted/lowered the system volume before shutdown, the chime would not be played, but so far it's not working on this version!

Onyx can disable it

Titanium Software | Operating System Utilities for Mac - OnyX

OnyX is a multifunction utility that you can use to verify the startup disk and the structure of its system files; run cleaning and computer maintenance tasks; configure some hidden parameters of many Apple applications; and more.

I also just noticed the startup gong on my iMac 2020 with Catalina 10.15.7 after the security update 2020-001. It surprised me.

Same here with a 2018 Mac mini. In addition to the unexpected chime now sounding, I'm also seeing the Apple logo on powerup with my eGPU, which never showed before.

Same here, MacBook Pro 16" 2019. A loud chime was played during the update process. Very annoying.
Hope Apple will bring an option to disable it in the System Preference.

I don't mind the startup chime, I just wish it would follow the volume setting. With the volume muted the startup chime is muted, but with any other volume setting the chime is FULL BLAST!

When I was on Mojave, there was a command that you can type into terminal to turn it on. I’m sure the same command can be used to turn it off on Catalina.

OS X Daily had an article on how to do this:

I believe this is how I enabled the startup chime on my 2018 Mac mini when I bought it a few months ago.

Don't get me started with that blasted security update. My Catalina 10.15.7 would not install it. I finally had to reinstall from recovery and then migrate my data back. When it finally started up, the chime startled the bejezuz out of me.

Does anyone know how to adjust the volume of the startup chime and not just shut it off????
