Well, first I must apologize, my english is really basic, but I know you will understand

Since a few days ago, I've been trying to build a server to play with some friends around the world, but I still can't find the way to make it work... there's so much tutorials to build servers on windows, but nothing can helps me with my mac, there isn't cracked files, no way to use the k'ed "iw3mps.exe" cuz .exe files doesn't run on mac, nothing explains what is needed, how to use it or anything else!

Every port is running well, I learnt every command on console... I just don't know what else can I do...

I hope that someone can help me

Hello,

I am guessing you'd need a Windows or Linux-based computer to host a dedicated server. You may be able to start a peer-to-peer server when you open up your game through your Mac, but I am guessing that is not what you want. (you'd have to keep your game on for as long as you want to host it).

You may want to check out a host like www.gameservers.com. You won't have to worry about setting it up, just getting it configured.
