I don't see a solution posted for this. I am unable to run a Unity-based app that works on Android and iOS, as a Mac version. I just wish to run it only local MAC It builds just fine but each time I go to run it, it reports Failed to validate Mac Appstore receipt. But this is not an app in the App Store.

Good question. No clue how they gather this iinformation. Been using AppFigures.com which appears to present a lot of data for every app Including the ranking of keywords associated with each apo. Those keywords lead to searches returning the app.
