Can't play on macSierra

[Nepposs]

When I launch the game it gives me the activation code but after when I click on play it puts me the problem report how I could play without downloading something? Thank you

I have the same exact problem, so I found a way to play but u cant play multiplayer. Go to common apps in the steam folder then right click acb and show package contents then open one of the terminals and itll load up. U cant have the steam overlay tho.
