Nostalrius Begins - Quality wow vanilla realm (1.12)

I just logged in for the first time on Mac OSX and created an orc shaman. Any mobs that I attack instantly evade. If I join a group with someone on PC we can kill the mobs when they initiate, but I can not initiate any mobs due to the evading. I have no mods or add ons and I downloaded from the nostalrius website. Help?

Weird. Sounds like your toon can't be targeted directly, so you'd have to find a mob that does AOE damage to test that idea. For the hell of it make another toon and see if the same thing happens. If it does, I'd download the client again. I don't think this has anything to do with Mac.
