When starting SC4, I get a popup to enter my AppleID and password because "SimCity was purchased using the App Store on another computer." This happens after installing the NAM39, industry multiplier, and radius doubler mods...then save a couple of cities in a region...then exit the game. After entering the ID and password, I get the "app is damaged" popup and the game won't load. I know Catalina update has been an overall problem/challenge...just curious if anyone else has had similar problems with the full version from the App Store.
