If you're using a document-based approach, then you should simply call
NSDocument's updateChangeCount: method, with the constants NSChangeDone
and NSChangeUndone. If you're not, then I suggest you replace your
edited flag with an edit count, and code your own updateChangeCount:
method to manage it.

Hi folks.
I have an NSTextView that i am using as a text-editor. When the
contents are changed, i set a flag to say that Edited=True, and use
[NSWindow setDocumentEdited:hasChanged] to notify the window that an
edit has happened (sets the little dot in the red top-left button).
Now if I do apple+z to undo, then my text-editor is now not edited -
however I am not sure how to check this - I am thinking it may be
possible to look at the Undo-stack, and if nothing is on it then I can
assume that an edit has not happened? Is this a good approach to take?
Can anyone offer any advice?
Cheers.
