A lot of people ask this question and to be honest in my six years of Macintoshing i have never seen an autorun macintosh CD. I could be wrong. The quicktime player will automatically start playing audio CD's but i've never seen a program actually start when i popped in the CD. The thing most companies do for mac CD's is use a program that arranges the folder icons in the CD-Rom's window to resemble a picture, there are several shareware apps that do this, you take a pic from photoshop or fireworks import it into one of these fancy shmancy programs and you've got a picture in your folder. I don't recall the exact names, but i've got about 5 on my old macaddict CD's. Don't worry about an autostart with a mac, we don't use 'em and most of us would rather dink around in the CD rather than have it just pop up on it's own.
