"Updated" Tone Plays Frequently But Don't Know Why

[jason.siegel]

About once a day, my Mac makes a tone, and I don't know the cause. I think it's the sound the Microsoft Office software update program would make to indicate there was updated software when I opened it periodically. I don't see any open programs though that seem to be causing this, and it's persistent. Any ideas? It's driving me nuts.

Thanks. There's nothing in Notification Center that can explain this however.

I uninstalled a bunch of apps to try to find the culprit, but to no avail. Any other thoughts?

You can disable Microsoft's AutoUpdate launch agent with

sudo defaults write /Library/LaunchAgents/com.microsoft.update.agent.plist Disabled -bool YES

and restart.
You can manually check for updates by opening /Library/Application Support/Microsoft/MAU2.0/Microsoft AutoUpdate.app

Thanks. To clarify, I meant it's the same sound but not necessarily the Microsoft AutoUpdate. I'm trying to figure out what is actually causing it.

Check the launch agents in ~/Library/LaunchAgents and /Library/LaunchAgents. Microsoft's AutoUpdate agent has a start interval set to 43200 seconds, that's once every 12 hours.
