OS meaning Mac? There's a Mac version but it's finicky to get working unless you know what you're doing
Maybe you should be complaining to mac. Either.. get a cheap, old android phone thatll run the program.. or get a pc. or get that program that can switch your mac from OS to Windows operating system. its free.. wish i remembered the name of it. i used to have it.
Or.. theres a mobile system called BLUESTACKS. Download that and you can run android operating system on a computer. might work for your mac.
use that.. then download the android game onto you bluestacks program and run it
