I am experiencing a strange problem: after I installed a bunch of updates, the Mac AppStore badge was not reset. When I go to "Updates", I get the message "no updates available". I tried to

  • delete the AppStore cookie
  • rebuild the Spotlight index (found a recommendation to do so somewhere)
  • logged out and in the AppStore
  • delete some of the updated Apps and re-installed them

without any effect. Today, I got an update for another application; the update count was incremented and was not reset again.

Any ideas?

Rather than rebooting, you can just type killall Dock from your terminal application. It will reset the dock and clear the badges.

  • That trick didn't work for me. The badge was removed for a few moments, but popped up again.

  • Did the new alerts pop up because you had valid messages? The killall Dock is something Apple actually recommends on their support site.

  • No, there weren't any updates at that time. After one update was available the problem is now resolved for me.

A reboot did the trick. Badge is reset.
