Where is the sound file of Installer success stored? I've tracked Installer.app to be located at /System/Library/CoreServices/ but I can't find the sound that plays after a successful installation.

I've looked at the following paths:


/System/Library/PrivateFrameworks/Install.framework
/System/Library/CoreServices/Installer.app
/System/Library/Sounds


Where is that sound file located?
The file you are looking for (on El Capitan) is located in: /System/Library/Components/CoreAudio.component/Contents/SharedSupport/SystemSounds/system/

Specifically, the file is burn complete.aif (or burn failed.aif, they're identical).

Older versions of OS X (unknown when it changed) have it at (source):
/System/Library/Components/CoreAudio.component/Contents/Resources/SystemSounds/system/
