The toolkit is not meant to just let you port the app directly from iPad to Mac even though you can. Just like you can just press a button and have an “iPad app”, you should make affordances for the Mac just like you do when moving an app from the iPhone to the iPad. That’s the entire point of the article.

To get an idea, the developer has been playing with a tool he wrote that lets him take an x86 build of an iOS app - when you run any iOS app in the simulator it creates an x86 build - and “marzanipies” it.

For instance he took a binary build of Marco’s Overcast app (with permission) and turned it into a Mac app.
