When I use my MB for an extended amount of time, my MB will not restart or shut down unless I hard shut down. When I try to do it, a pop up says that Finder (or some other application) has failed to turn off and that I need to force quit the program before I try again. When I would go to force quit, the application would not be there or for Finder, clicking relaunch does nothing. If I don't use the MB for a long time I am able to turn it off without any problems. Is there something I can do to fix this?
