Honestly even if they did, it would be a gamble given the legal battle currently going on between Apple and Epic. Since TSW runs on the unreal engine created by Epic, Apple has cut Epic off (indefinitely) from all development tools for all Apple os devices. This means that as the unreal engine gets updated on other platforms, there would be no more updates to it on Apple devices and as developers update their games as well to be compatible with the updated engine, they won’t be able to update the game on Apple devices either since the engine would be out dated.
Maybe Apple comes up with a train sim? But honestly Apple does not deserve to run TSW. Good games are Microsoft PS Xbox every other system only.
