Hi @stormer1267 - EA sells the Origin version & Aspyr sells the App Store version. Unfortunately, you cannot transfer the license from one company to the other
Q: I already own SimCity on Windows PC/Mac through Origin. Can I get the Mac App Store version for free? Alternatively, can I get the Origin version for free if I purchase the game on the Mac App Store?
A: We are not able to provide copies of SimCity on the Mac App Store to owners of the Origin version.
