A friend of mine is having an issue running this on an M1 Mac. They can play for up to 40mins, and then they get a crash that forces the whole PC to restart. Sometimes it crashes in a shorter period of time.

There is a reddit thread that describes the same issue: https://www.reddit.com/r/macgaming/comments/p1838u/return_of_the_obra_dinn_shutdown_problem/

I don't have any solutions, but I thought it best to document the issue here.
