I've been having some problems with airport lately which I guess are common when you switch networks a lot because the mac gets confused. So today I came home after IT at my school fixed it for the most part (IE: they removed a bunch of excess networks from my network bar where they had been saved as preferencial networks) so I came home and connected to my network. When I typed in my password and hit enter a thing popped up that said "Allow Apple80021Agent to make changes?" I didn't know what else to do so I allowed it and then my internet works fine. Nothing is slow, nothing is there to indicate it was a virus. It's just weird though because I can't find anything about this on Google. Anyone know what this is? Is it just a program or...?
