Just installed the latest update on my iMac. Now, all of a sudden, that annoying, wake up the whole house, start up sound is back. Sounds like a frustrated organ player. I eliminated this wonderful feature right after I bought my iMac years ago, but I forgot how I did it. Can anybody help please. Thanks in advance.

1) Open Terminal
2) Type in sudo nvram SystemAudioVolume=%80
3) It will prompt for your password. You won't see the characters as you enter them, so you'll have to type it in 'blind' and press Enter. If you don't have a password, this won't work.
4) Restart the machine.
 
Thank you very much! I appreciate your help. It's always frustrating when Apple tries to take over my computer and makes decisions for me. Just sayin'.
[doublepost=1469202761][/doublepost]It worked!!! You're a genius. Thanks again.

Just note that the startup sound signals a particular stage of the boot cycle. Make it quieter? Sure. But if you eliminate it altogether you may run into extra challenges someday if the Mac needs troubleshooting. Booting to Recovery, Safe Boot, resetting NVRAM/PRAM... all of those keystroke combinations (and many others) need to be entered in the moments between the beginning of the startup sound and the arrival of the gray screen.

So noted. Thanks, but I think I'll take my chances. I don't always remember to turn my sound down and that loud, obnoxious sound sent me straight to the ceiling this morning. I'm 71 and could have a heart attack just signing on. Thanks again.

I think it is time for a new startup tone. I miss the 90's when they were always changing. It gave the machines a personality. The Quadra 800 with the PPC 601 card in it was my favorite. I think the 840av used it. The current sound is getting old.

LOL, at 71 give thanks you still have good hearing! Lots of folks your age walking around with hearing aids. :rolleyes:

Came here to make a similar comment.
The startup sound is an inherent part of the Mac experience . Love it.
 
If you shut off your sound before you shut down by pressing F9, you will not get a startup chime when you reboot.
