Its really confusing, because you have servers for the game up, but you don't have the game on the list! I'm new-ish to this stuff, but if someone can explain how I can add the game to the list, it would help me so much! Thanks

Hi clearpatrick,

The Mac version of L4D2 was released after our last Mac GT Lite update, therefore we haven't added support for this game just yet.

Your servers list contains servers from your account. If you have added L4D2 servers to your account, they will show in the servers list. Since the game isn't supported by the Mac client yet, GT Lite will not detect you playing L4D2 or allow you to launch L4D2 into a server.

Let me know if you have any additional questions!
