Since updating to 10.9.2, some of my programs won't open and my webcam is not working either (2008 Macbook Pro). Facetime freezes when I try and open it. Other programs that aren't opening include iTunes, VLC Player. So far. Here's a sample from the Console: 3/19/14 7:47:01.765 PM iTunes: Can't open input server /Library/InputManagers/MultiClutchInputManager.bundle Similar message earlier from other apps mentioning MultiClutchInputManager.bundle. It does not exist in that directory. What is it, and is that what is causing my problems? Thanks everybody! EDIT: This accompanies that message for iTunes: 3/19/14 7:52:34.823 PM com.apple.MediaLibraryService: void *NSMapGet(NSMapTable *, const void *): map table argument is NULL THOUSANDS of those identical entries at the exact same time. Any correlation?
