I was running the Tweetbot for Mac Beta, and still had it installed when I installed the full release from the Mac App Store.

Now I have 2 entries in my preferences for Notification Center, and I don't know which is which. I have removed the Beta application, and only have the real thing installed, but oddly whereas the Beta had the 'Egg" icon rather than the bird, both set of preferences use the bird icon.

Where does this preference pane get it's information about installed applications? How can I remove an app from the list?

  • I too have this issue. I've even tried deleting Tweetbot, but one of the icons still remains. Most likely the beta one. I don't know how to get rid of it. Commented Nov 8, 2012 at 16:11
  • Apparently this issue still persists in macOS 10.13 (High Sierra). I have several apps that show up twice (Brave Browser, Google Chrome, for instance). Commented Oct 4, 2019 at 19:38

Open terminal and run this command:

/System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchServices.framework/Versions/A/Support/lsregister -kill -r -domain local -domain system -domain user && pkill Finder

Or, if you have OnyX utility app, go to "Maintenance" > "Rebuild" > check on "LaunchServices" (leave the other options unchecked) > execute

  • I am using OnyX 3.1.6 and it didn't work. Did it two times, no luck. Commented May 16, 2016 at 15:39

    Does this reset existing preferences for notifications? Commented Apr 17, 2019 at 23:08
