I don't want to cool your enthusiasm, but until Macromedia releases a production product, you won't get any support for a production CFMX web site on the Mac.
If you are the person who successfully entered pc serial numbers for JRun and CFMX then you may be hurting the issue. Macromedia is watching very closely to see if there is enough interest to ramp up to sell a production product for the Mac.
By using pc serial numbers, you show up as a pc user and not someone who wants to run on the Mac.
I suggest you contact Macromedia and tell them you want to run legitimately on the Mac.
