Ok Jman,
The mistake your making is you are putting the "World of Warcraft" Terminal file in your WoW directory. ~DO NOT DO THIS~
How to fix this: - You need to right click onto your "World of Warcraft" exe. file and go into "Show Package Contents" Then go into the file "Contents" -> then to "MacOS". Once you have done this, replace the "World of Warcraft" terminal file (downloaded from http://www.mediafire.com/?04a4zk16hzvxp8d) with the original "World of Warcraft" terminal.
This should fix your problem. Then just go back to your WoW directory and run World of Warcaft.
~DONT FORGET TO CHANGE REALMLIST~
