I have the same problem, but I'm having a hard time following these instructions. My "config" is a folder, not a file, and contains three files; none of which contain the "cmdlineadd" at all. Also, there is no file in my mac called 'SPORE Preferences'... Any help?
Did you open the game, so that the Spore Preferences folder can be created?
Navigate under-> Users/YourUserName/Library/Preferences/SPORE Preferences/
This is the correct path on mac, if you do not see anything, may game not be installed properly!
You must to completely uninstall it with the hidden files and reinstall it again.
