Nostalrius Begins - Quality wow vanilla realm (1.12)

I just downloaded Nostarlius, and selected "Test Realm Isvv2" because I didn't think it mattered. However, I just read that I have to re-name the file "realist.wtf".

How do I do that on a Mac? Will that let me sign into a server that doesn't disconnect me every time??

Thanks!

You don't have to rename squat.

Search the support forums, there's a nice, big stickied thread at the top with a guide that explains how to fix the Test Realm IsVV problem, complete with screenshots and everything.
