I have a WKWebView in an OSX app. everything works. except when the user clicks "Download Image" or "Download Linked File"... nothing seems to happen. I have navigation delegate set, I have ui delegate set. but none of their methods are called. I did redirect the menu item by changing them to call my own method, but there is not enough information passed to that method for me to work out the URL I'm supposed to download. If I know the URL, then I can handle the rest, I already have working code for that. thanks
