Verifying the purchase (receipt) of another application (Mac App Store)

TL;DR: Is there a way to verify that a user has purchased another app (of mine) from the Mac App Store?

In a brief, I want to completely rebrand one of my applications on the Mac App Store. The current version is very buggy and has a user base of nearly 90% pirates. I want to shut down the old application and completely rebrand it as a new product.

However, I don't want to completely screw over my current, legitimate customer base. I am hoping there is a solution to this. The way I was hoping to go about this was to:

The new app will have extensive anti-piracy measures. Furthermore, the current application requires a connection to one of my servers. When I release the rebranded app, I will shut down the current app.

I realize the forcing users to migrate may cause some backlash; however, I am hoping that, by providing the new and improved version 100% free, the backlash will pass.

  • Look for the old app using NSBundle bundleWithIdentifier
  • get the receipt of this bundle using appStoreReceiptURL
  • validate the receipt
  • unlock functionality

Bare in mind that the terms and conditions of Apple say something along the line of "only appstore IAP should be used to unlock features; don't roll your own license mechanism"
