I registered two games I bought from Walmart, in person, and I got free Sim points for the online Sims 3 Store. I'm running the required OS, Snow Leopard, but whenever I attempt to download what a purchased using my free Sim Points it never works. I read that I need the EA Download Manager but it isn't Mac compatible. Anyway around this and still using my Mac? And why would EA make a game for both Windows and Mac but only allow downloads for Windows?
