I have a static text string "passwords must match" that I show
whenever they don't. (to see the keystrokes, I made a delegate for
the password fields that overrides controlTextDidChange:, and to hide/
show the NSTextView, I call NSView's setHidden:).
If the person clicks <Save> anyway, I cause it to be ignored (a
delegate to NSSavePanel that overrides -(NSString*)
panel:userEnteredFilename:confirmed, and returns nil), AND I kick off
an animation loop that makes the text fade in and out every half
second. (NSViewAnimation)

I'm pretty certain there is no proper API for disabling the Save
button. But the delegate methods will allow you to stop the button
from taking effect (weird I know). I suggest you do an NSBeep() at
the same time to at least give some feedback as to why the panel
couldn't close.

I haven't tried myself, but just checking the headers it looks like
the closest thing would be to make your controlling class the
delegate and then implement either
- (BOOL)panel:(id)sender isValidFilename:(NSString *)filename;
or
- (NSString *)panel:(id)sender userEnteredFilename:(NSString *)
filename confirmed:(BOOL)okFlag;
since they control whether to allow the selection process to
complete. The docs for these methods have more details that might
help you decide which would be better.

I'm extending NSSavePanel by using an accessory view. The view
contains two NSSecureTextFields, to contain the user-typed
password and confirmation.
I know how to detect when the two password fields don't have
identical content, to display a warning string on the dialog, and
to prevent the user from exiting the dialog.
But I'd also like to disable the <Save> button. Is it possible?
