Okay, this is a little hard to follow since you're quoting style is, well,
non-existent. But, if this is a prefs file created and maintained by
CFPreferences, then you should be able to use the identifier used to create
it to access it. If for some reason that's not possible, but you can locate
the file, you can read it yourself and use other Core Foundation APIs to
parse it and look for the key, or do you just need to verify the existence
of something in the file you locate with a simple search?
