I'm a gamer and one day i was playing mine craft when this blabbering thing just showed up. I went to activity monitor and there was a process called com.apple.dock.extra. From the first day there was a annoying voice all the time and when i went to internet pages, i could not scroll down as it would go back up to the top again. Just yesterday i was playing mine craft when my up key stopped working. After some investigating, i think it has to do with com.apple.dock.extra. Whenever i press up, the annoying little black box goes up to multiple links and says them out to me. Finally, there is a big black box that appears telling me where my system is. My computer is a 13 inch MacBook Air version 10.7.4 and i have Mac OS X Lion 10.7.4. I have a 1.8 GHZ processor. Could someone PLEASE tell me how to fix it, as this is my school computer.

  • Does this happen when you quit Finder (open finder then press command+q)? – Benedikt S. Vogler Jul 26 '16 at 13:20

You could try this fix:

In Finder use the Go to and go to /System/Library/CoreServices/Dock.app/Contents/XPCServices

In XPCServices Folder and move the com.apple.dock.extra.xpc file to desktop.

Then go back to the activity monitor and force quit the process and test!

    NO! DO NOT DO THIS! Never ever delete anything inside /System. – ganbustein Jan 25 '15 at 7:21
  • @ganbustein you are right, lets not delete, lets just move it for now. – Ruskes Jan 25 '15 at 7:37
