Power Up/Down Sound Effects?

[tactician1016]

Is there a way to set
A) a different sound for when I power on?
B) a sound effect for when I power down?
I already have a .aif file for the latter.

Unless you'd like to mess with the EFI, then no.

 

[tactician1016]

The what?

The EFI is a chip on Apple motherboards that controls hardware-level input and output. It is the equivalent of BIOS on most PC motherboards.

The Apple startup chime is hard-coded onto that EFI chip, and it indicates that the hardware passed its equivalent of a POST test; it's not a software-enabled startup sound like in Windows. One would have to reprogram the EFI to change the chime.

Trust me, if there were an easy way to change it, I would've already changed mine to a quote from a particularly funny Apple "Mac vs. PC" ad:

"Mac has issued a salutation. Cancel or Allow?"

EDIT: There may be a third-party app for enabling sounds to be attached to Mac OS startup and shutdown, like Windows. Unfortunately, I can't think of any names right now, and they wouldn't replace the Apple chime anyway.

So, startup is a definite no, shutdown probable no? Darn.

Shutdown's easy, actually. Just put an alias to the file in the /Library/ShutdownItems folder. It may be best to create an Automator action that will quit itself after it plays, just because I don't know how the system would handle opening a file in iTunes or Quicktime while trying to shut down, but the general principle is straightforward.

I see. Where might I find the shutdown items folder?

I wasn't keen on the default startup chime, so I downloaded StartupSound.prefPane and muted it!

You probably will have to create it. Be careful of the exact capitalization and spacing, I believe it should be "ShutdownItems" without a space. If it doesn't work, you can try it with the space.

So, just put a link to the file in the folder? seems simple enough.

 

[tactician1016]

no luck

I put the folder in the Library, with the audio file. No luck. Any ideas?

I've tried this before, and it seems to work:

StartupSound.prefPane

That's only to change volume though.
