I like this game. I really do (I already played it on my old PC). However, the Mac version suffers from a very annoying bug in non-English localizations: Lots of tags are displayed on-screen so that the text is effectively rendered incomprehensible. Unfortunately the game doesn't let you choose your language but auto-detects which one your system is set too as default.
As a workaround, it is possible to switch your OsX to English as the display language before starting the game and switching back afterwards. An annoying procedure at first, and an infuriating one as you have to repeat over and over. Please get a patch from the developers!
