Today, I bought the shareware app "little snitch," which is pretty much a dedicated outgoing firewall— it stops applications from having unauthorized access to the internet. You make "rules" about which apps can and cannot use the internet. So, when I fired up Nexuiz, little snitch stopped it from connecting, and Nexuiz could not get past the gray start screen. After I allowed Nexuiz all internet access, it worked fine. Sooooo, if any mac os users are having problems getting past the "welcome to nexuiz" bit, it might be because you have the snitch installed.
