I know this issue of "Could not connect to Steam please restart Steam," is a common issue, but all of the suggestions I have seen have been for Windows.

For example, http://www.berserk-games.com/forums/...hp/t-1235.html suggests reinstalling x86 version of 2010 visual c++ but I can't do that on mac.

I have deleted it and reinstalled it, verified the game cache, and have also double checked for firewalls and none of that has worked.

Please let me know if I can provide more information to help!
