Also, don't know if this matters, but I am running from a folder copied over by migration assistant. I did not run and install using Steam.

More details; MacBook Air late 2020, M1 chip, 8 gigs ram, 7 core graphics. terrain detail high Render quality fantastic Texture quality Full Res Screen Resolution 1650x1050 KSP 1,10, Making History, and Breaking Ground, only mod is MechJeb Load time is 1:18 to main menu Just flew a mission to Duna and back, with a mother ship and a lander. The game ran smoothly with no noticeable drops in framerate or glitches. The clock was always in the green. The laptop did get noticeably warm, but not hot. It is a battery hog. The two hours of play time used up 50% of the battery. This is frankly a fantastic little laptop.

Got my new M1 Mackbook Air today. KSP runs very well under Rosetta 2. The clock stayed in the green launching a 141 part ship to orbit with all the graphics turned up. Very happy.
