I am lost. You said that your soundandbeyond software (?) is not compatible with your Mac.
You mean that you need the ID from Mac so that you want to install it on your IBM PC. Is that right?
If yes, it won't work that way unless you have a Boot Camp on your Mac (OS Leopard) with the Intel chip that will run an IBM PC software. Without the Intel chip on Mac, you are out of luck. I don't have the Intel. Someday, I might one.
If your CD package has a serial number for your computer, you can install it and it will ask you for your CD's serial number.
