Playing on 09' Macbook but with 10.9.1. Followed all instructions, tried playing through Steam and after 3 patches it continues to give me the same error of error in download, check your connection. Yet my internet is not a problem, and I have all firewalls off to let this go through. Not to mention this game is in the Titan Fury xpac, but yet during the patching it was showing only Eternal Crusade. When I tried the torrent option it got a little bit further, but after about 20 minutes of downloading it gave me the same error.
