Mac App Store app purchase protection

Hi, I have published an app on the mac app store (for a fee). I subsequently did this test on two of my macs (with totally different accounts)



- Mac 1 -> App bought regularly.

- Mac 2 -> Application received from Mac 1, via airdrop (nomeapp.app) and fully functional (indeed it is even purchased, and the "open" button appears instead of the price.



How is it possible? is there no control from Apple like it does on the iPhone?



Is it possible to avoid this thing?



Thank you.

Are you validating the receipt?

Sorry. What do you mean? it's the first time I publish on the MacApp Store. thank you

Not much else to say. It is the developer's responsibility to implement a DRM system. This is also true on iOS. It is more difficult to do these things on iOS, but lots of people jailbreak their phones for this.


You can validate your receipt locally, without a network connection, and/or you can do it with an Apple web service.

Thank you so much can you direct me or dare some suggestions / tutorials to follow to implement such a thing on the Mac app? (

(a service without internet connection)
no for in-app purchase

Thanks again
