Mac vs PC stats

[Xander]

Hi I wondered if anyone knew a website showing the stats for percentage of Mac users. I'm making a CD for a client and they are worried about it being cross platform compatible, I have burnt a cross platform disc from PC on Nero 7 but you need to copy the file to desktop to run it for Mac, and obviously its not the easiest thing for them to do but.... People who have macs are gonna be used to dealing with these things right? And pc software not working.

Trying to find an article kinda explaining this stuff (and what sort of people have macs, and why etc) but if anyone can sum it up or knows any stats/info that would be good
