As you have noticed, we have had crash problems when launching the game via Steam on the Mac. We have come to the conclusion that there is a problem between our launcher and the Steam overlay. The previous workaround was shutting off the Steam overlay, but after a recent update to Steam that no longer seems to work.
So, we are doing the following things to solve this problem:
1) We are currently working on a new launcher that you will see a first version of very soon. It should not have these problems, and eventually it will have some nice extra features.
2) As of now, when you click PLAY in Steam on Mac you will no longer go via the launcher, but the game will start immediately. The unfortunate side effect of this is that you cannot turn off DLCs, nor mods, when launching this way.
3) Then there is a workaround. If you want to use the launcher to, say, turn off DLCs, you can still start it manually. To do this, go to the ck2 install-folder in the console and start ./CrusaderKings2.app/Contents/MacOS/CrusaderKings2 . As long as Steam is running in the background you should still have MP etc.
Again, we are working on getting out a new launcher but in the meantime you should be able to enjoy the game.
