it's just the /apply url that does the windows check. the rest of the site can be viewed from any os.
You should probably change that to the entire site, so people know about this idiocy immediately and don't waste time with you.
I think you are missing the point. 100s of people are applying. When they get into the school 10% have a pc not a Mac. It's not worth that 10%. I'm going to teach the other 90% that have Macs already. That's plenty of students. Why would it be wasting time with me? I'm a great teacher and coder.
