Universal purchases, which will allow developers to offer an app across Apple’s platforms, are now available for Mac apps. In a short notice posted to Apple’s developer news site, the company said:
The macOS version of your app can now be included in a universal purchase, allowing customers to enjoy your app and in‑app purchases across iOS, iPadOS, macOS, watchOS, and tvOS by purchasing only once. Get started by using a single bundle ID for your apps in Xcode and setting up your app record for universal purchase in App Store Connect.
The feature began appearing for some developers on App Store Connect a little earlier in the day:
I was (finally) able to add a MacOS Platform to our iOS app in App Store Connect today. If you tap the + button App Store page for the app, it now lists “MacOS” in addition to iOS and tvOS.

Prior to universal purchase, Mac apps were treated as separate products by Apple’s stores, which meant developers had to either charge separately for apps and, in some cases, jump through complex receipt-checking hoops to bundle their apps. This change should make the process of charging a single price or signing up for one subscription for apps across the Mac, iOS, iPadOS, watchOS, and tvOS much simpler and will enable cross-platform In-App purchases too.
