School WI-FI DOES NOT SUPPORT MAC

Today I was in school doing accounting practicing with my friend, and I took my ibook to school. I tried to use my laptop to connect internet, but I could not connect, my friend told me I have to go down to computer office to apply again.I went to 4th Floor to see the computer guy.
His door was closed and through the window, I saw him, sitting on his chair and trying to avoid me, that moment I thought "umm. not a MAC friendly guy ). I waited for a min, he left his chair and opened the door, and said...

"Sorry School does not support MAC, and we do not give away passwords for students now"

I was like "what? how come school WI-FI do not support MAC? it just setting up a mac address and passwords, is that difficult to set up?" but I didnt say that to him. I went back to my friend and told him that, but at that moment, I didn't think that much.

After few hours, before we left the school , I mentioned that to my friend, and he suggested to talked to people in head office, and I went to tell them, nobody know about MAC thing....and they suggested me to talk to the manager tomorrow.

So I decided tomorrow, I will take my laptop to go to that computer guy again, and ask him why it doesn't support MAC... otherwise I will report to main campus to complain about it....
