Making in app purchase available for Mac & iOS

Question

I've got app for iOS and Mac which has all functionality unlocked with single in app purchase.

But now it's separate in app purchase on Mac & Separate for iOS. I wonder if it's possible to have one in app purchase which could unlock both iOS and Mac.

Update: I wonder if Apple provides mechanism for it.

Answer 1

It is possible, but you need your server where you could track licenses. Many apps do that e.g. like Office 365.
