My white MacBook occasionally will not respond to the shut down command either from the Apple menu or from the panel brought up by a brief press of the power button. The shut down process starts - the option to shut down in 120 secs panel appears and the top menu bar disappears - but then the set just hangs. After a minute or so a panel appears with the message that shut down has been cancelled because one or other app failed to quit. The relevant app is not open (I double check using Force Quit) and the only way to shut down is to hold down the power button. I have run repair permissions and verify disk and there are no problems shown. Does any one have any idea please what the problem is and how I can cure it? Thank you.

    You will need to note which applications failed to quit at shutdown. There is an obvious problem when this happens, and the problem is associated with the indicated application(s). There may be a problem with a corrupted preference or cache file that is causing the application(s) to hang.

    You can start by deleting the preference file(s) of the suspect application(s). You will find them in the /Home/Library/Preferences/ folder. Usually they are in the form of "com.author.applicationname.plist." Then download and install AppleJack - VersionTracker or MacUpdate. Read the documentation carefully then use the program as instructed. See if that helps.

    I'm not sure what to tell you to do if the computer does not respond to the various startup shortcuts. This would be indicative of some sort of hardware problem.

    If you are unable to use AppleJack, then you can try using one of the various utilities like TinkerTool System to clear caches. But this would not do anything to "fix" the inability to use startup shortcuts. This problem would be related to the keyboard in some way. Startup shortcuts are recognized by the computer's firmware and should not be dependent upon OS X.
