My app (macOS 12) observes a value in NSUserDefaults.
Starting with macOS 12 observeValueForKeyPath:… is called at the start of the program, although nothing has changed yet.
When the value actually changes, it is called twice.
Also: NSKeyValueObservingOptionNew or NSKeyValueObservingOptionOld just return NSNull instead of old or new values.
Any workaround for these multiple (and unnecessary) calls?
Gerriet.
