i wrote the same report yesterday on steam, but no reaction… so here again:
Today i installed Train Fever successfully and i was able to play 3-4 hours (i was able to switch back to mac os with cmd+tab). After this i quit the game and steam.
Some hours later i opened steam and started Train Fever again, but some menus in the game were missing. since this i am not able to switch back to mac os with cmd+tab anymore. i tried to run the game several times (every 3rd try i received no black screen), sometimes i was able to enter the game, but after the 10th (?) try i can see only the black screen without entering the main menu, but music is playing.
So i deleted Train Fever (local files in steam) and installed it again. but no changes. i disabled steam overlay in the game. but no changes. i tried this several times… at the end i deleted and installed steam, but no changes.

Is there an error-logfile? if yes: where is it located?
Looking at the minimum specs you are all good, except for the graphics card. I’m not familiar with Intel graphics, but it’s not mentioned in the minimum specs, so my guess is the Intel graphics don’t support all the tech needed.
