I completed the tutorial on my mac, but my experience was not great.

• game started off in windowed mode and the window was larger than the screen
• all the text is very hard to read. It is blurry on a mac. I tried it on Windows and it's not blurry.
• one time, the game crashed while I was in the middle of a mission.
• multiple times, the game crashed at the end of a mission after I clicked "exit game" from the stats screen
• the fans were whirring, the computer was getting hot, things seemed sluggish at times.  this differs from when I switched to my windows partition on the exact same computer.

In the current state of things, I won't be playing this game on OSX until there are some fixes for the blurry text and crashes.
