EB on Mac OS

Hi Everybody,
I just switched from Windows to Mac in order (I hope) to play EB a more comfortable way. I am about to receive the Mac version of RTW in a couple of days. I'm downloading right now the recommended files for the Mod (RomeModSetup + EB data files) The question is : after the installation of RTW is complete which of the two EB files should I open first ?
I've seen that these two files have been downloaded nearly 3000 times. I suppose that some of you might help me install the game without too many problems :-)
Thanks in advance.
