Okay. i just updated my computer to OS X Sierra. My first run went great, there was less crashing, even when i tried to make it crash. today when i tried to play, it won't let me run it at all. it instantly crashes. so i re downloaded the game, the same, i redownloaded the PlayOnMac thingy + the Game and got same result. i took my computer into the apple store last night [complaining that my microphone won't work] they checked what was wrong with the machine [running diagnostics] i don't know if that wouldve affected the game in any way shape or form.
