I have always just burned the ISO to a CD on a Mac, and then mounted it using the "C" key during system bootup.
Never had a problem doing that on any machine... works every time. I have read endless reports of people trying and failing to use a USB key to install debian on PPC machines, however. Sometimes it seems to work for some people -- usually it seems people have lots of trouble. Does your CD drive not work?
