I’ve tried it on an 27″ iMAc (2011) mit 1 GB ATI 5750, 24 GB RAM. OS 10.9.4
Yesterday evening i coud play it for 4 hours and today it Crashs always. I can not load my savegames or start a new game. I have tried to change the graphics settings to minimum, and no change to the crash.
A Test on a MacPro 2008 (8 Core 2,8 Ghz, 20 GB, 1 GB ATI 5770 GrahicsCard), the same.
Please FIX
