Zampella added in his Tweeting that he thinks Aspyr should do it and they specialize in porting PC games to the Mac platform and they have recently finished BioShock Infinite and Borderlands 2 for the Mac.
While it is good to know that Zampella is on board to make Titanfall happen on the Mac, it is still a long way from completed. Even if Aspyr does commit to doing a Mac port of Titanfall, it will still be some time before it arrives on store shelves or in the Apple Store for Mac owners to buy. We are talking months here folks, not weeks. Still the news has to be viewed as a positive for Mac gamers as more and more PC developers are talking about Mac ports which the number of Mac gamers continues to grow.
