Mac App Store App and identifierForVendor

Question

To uniquely identify an App in iOS 6 and above you use this code:

UIDevice.currentDevice().identifierForVendor

Is there an equivalent for Mac OSX?

Answer 1

For the record and users searching SO for this matter: Apple documentation about validating a purchase receipt gives the implementation tip to get the GUID of a Mac, as the equivalent procedure for identifierForVendor: Get the GUID in macOS

It is MAC address based, but is the choice of Apple for purchase hash control.
