I have a Mac and now the game just returns a blank screen when I open it (thru Steam). I cannot do anything since it’s all blank.
Please help, it’s my favourite game 
I don’t think it actually works through steam yet, you have to download it directly.
it worked just fine before! it just crashed all of a sudden then other day. i mean i downloaded it thru steam but i play it on my mac
I just don’t know where to start. Are you sure you’re talking about Big Pharma? The game is neither out on Steam nor available on Mac yet. Some people are playing it using a Windows emulator on Mac but that’s not officially supported. Could you give me some more information?
