Currently SP for mac still has 2 bugs that really make the game less enjoyable. First is the largest, all the planes I fly on my Mac roll constantly right or left! It s getting out of control and it seems like the devs don't know it exists. Next is less important, but still a bug, the ice base location is un discoverable for me, I've tried just about everything to get it to discover, but not avail there is not even an airport! SP is an amazing game and I absolutely love it and the effort put in by the devs, because of this I don't want ios users like myself to be hindered or discouraged.
