1.1.1 is the latest patch, so if that's what version you're showing, then you're up to date. There have been some issues with Yosmite, as khh said. Some of those seem to be issues on Apple's end. Not to say that's necessarily the case here; I don't know enough about your situation.
There may be another patch in the future, but we have no idea when that will be as it stands right now.
Make sure you don't have any background programs running while you're trying to run the game. Since 4GB of RAM is the minimum requirement, that might be why you're having lag. ...I can't remember if there's any Mac specific tips for helping with that.
Can you give some more detail about the sort of lag you're experiencing? Is it everywhere, or just in Europolis? Also, if you visit the FAQ I linked above, it'll tell you how to get system diagnostic / log files that RTG can use to help diagnose your problem if we can't find a work around.Go to the full post
