Connect controller via bluetooth - Done. You dont want to use a mouse anyway because of the latency. The latency is alright for most games with a controller though. Atleast if the servers arent too far away and your connection is somewhat good. I had a free trial month for one of the services and it was pretty useable tbh.
Dont get me wrong i dont like Apple, Geforce Now or cloud anything either. But if a nongamer is able to subscribe to a service for a month or two to play that one game on his macbook thats not a bad thing? Like good for him.
