actually, the setup is completely different for OS X/Linux. See my linked article. Just type this in the terminal, and you’ll be up and running in OS X:
echo "PATH=\$PATH:/Applications/Autodesk/maya2014/Maya.app/Contents/MacOS/" >> ~/.bash_profile
source ~/.bash_profile
for Linux it would be:
echo "PATH=\$PATH:/usr/autodesk/maya2014-x64/bin/" >> ~/.bash_profile
source ~/.bash_profile
