At apparently random times, I hear the "glass" notification sound. There is no notification or alert that pops up on screen when I hear the sound, and the sound will happen even when I'm no using the computer (like when the screensaver is active or the display is off). I've tried turning off various potential culprits like iTunes--I thought perhaps the sound was from the wi-fi syncs completing with my iOS devices, but it still makes the sound even with iTunes closed!


I'm not sure if the sync still happens even without iTunes being active, but normally when it is, I'll see an "iPhone sync complete" message in the playhead when a sync DOES occur. Also, there seem to be no preferences for alert/notification sounds within iTunes.


I'm not using any chat applications like Skype, iChat, or Adium: only TotalFinder, Firefox, and Overflow. I have iStat Menus running in my menu bar.


I've tried browsing through the Console log, but I can't find anything that seems to line up with the time that I heard the sound. Does anyone have any ideas as to where this "glass" sound effect is coming from, and how I might be able to shut it off?

    MIght not be an Apple app. Look through your third party programs>preferences for possible culprits.

    It turns out it's happening every 20 minutes, on the "8"-- 3:38, 3:58, 4:08.

    Sounds like you have some kind of alarm clock app installed.  Have you installed any?  If so check your login items.

    At first, based on your description, I thought it might be alerting you that a new message has arrived.  In Mail's "Preferences>General" you have the option to make the "New Message" alert sound "Ping" or "Glass" among others.  However, the frequency options are manually or every 1, 5, 15 or 30 minutes, but no option for every 20 minutes.


    If you don't use and if it turns out not to be Firefox, check your email app.
