  Definitely get rid of the apply button. :-)

  I recommend using KVO/KVC and Bindings (read the documentation for
details). This allows you to use NSUserDefaultsController to apply
preference changes immediately. It also allows you to use the
validation method -validateValue:forKeyPath:error: to take immediate
corrective action. See this doc for a good overview of the process:

  Without specific details about some of the settings and the nature
of their dependencies, that's about as detailed as anybody can get.
