i learned in another thread that the volume for the startup chime is set by the volume level last set while no external speakers are plugged into the computer. I too, had a very loud startup chime, and always had external speakers plugged in. Upon disconnecting the speakers and lowering the volume on the keyboard, the startup chime is now set much lower.
ive tried the start up ninja app and also tried muting my imac before turning it off both methods don't work for me i have a set of external speakers plugged in but they are turned off when i fire my imac up im not to sure about changing lines of program unless its pretty simple
Solution #2: Via the Command Line in Terminal
You can completely disable the chime, there is a command line you can enter while in Terminal that will silence the chime until you turn it back on again.
Just open up the Terminal application, you can find it in Applications -> Terminal, and enter the following on the command line:
Code:[B]sudo nvram SystemAudioVolume=%80[/B]
Youll need to enter the Administrator password when you enter this command.
If you decide youd like to reenable the system chime, simply enter the following on the command line:
sudo nvram -d SystemAudioVolume
Again, youll need to enter the Administrator password to execute this command.
Hi Guys,
When I first switch on the iMac for the day, I always get the loud sonic boom, even if I have the sound muted
Is there a way to stop it or do I just have to live with it?

How does that deteriorate the HDD?
It is excessive read write cycles. A Hard Drive theoretically has an infinite amount of read writes compared to a HDD, but there is two main things that deteriorate its lifespan, heat and boot up/down cycles.
Now, you told me above that you have an SSD rather than a HDD, so shutting down and booting up is even worse. An SSD has a set number of writes it can perform. This number is usually so high that something else in your computer will go wrong before it. But having excessive read/writes on it is just wasting it. It's like deframenting as SSD.
SSDs and HDDs used in modern computers have so many write cycles that you'd have to rewrite tens of gigabytes daily to see any significant degradation within a computer's normal 5 year lifespan.
Shut it down if you want without fear of wearing anything out. However, the iMac's sleep mode uses very little electricity and wakes up nearly instantly versus rebooting.
It is unnecessary read writes.
