So I wanted to play mars again and now there's a window that wants me to open the browser. When I do so the game hangs and I have to force it to close and the window is still there when I open the game again. Which makes it impossible to play it on this machine

I have same problem too. Maybe it's happen because I run game on old Mac (mid 2012). it's frustrating.

I'm on a 2018 mac and it does the same thing,

I have the same problem, i cant get rid of the prompt and its really frustaiting not being able to play the game!!
I hope anyone on the developers team reads this and give us a solution cause its really anoying

I'm having the same problem, I just bought this game and it is super annoying.
