I know that on a PC you can do allthis wacky stuff with creating players and such. But what I really want to learn is if there is anything I can o to my game with my MAc. FOr example create a player or something!

There aren't any editors for the Mac.

What's all this shouting, we'll have no trouble here?... [/Local]

You can purchase a program named parallels which allows you to run a virtual windows os within your mac OS and from there you can run a windows pregame editor to create players and make any additional changes the editor allows.

I was under the impression that the database structures were slightly different between the MAC and PC versions and that they are not cross-platformable. Meaning that you can not take the roster updates for the PC and use them on the MAC.
Am I wrong on this?

I've had no problem using any of the alternative rosters on my Mac.

However, saved games are not cross platform.
