Ok, I got this addon, CTMod to work, but I didn't use the Stuffit Expander like the website I referred to said. Here is what I did... ..
I downloaded CT_Core from
http://www.ctmod.net/downloads.ctOnce the file was downloaded, I gutted the file by moveing the file's content to ..worldofwarcraft/interface/addons
Once I did that I opened up the game, jumped on, and sure enough the addon had worked. I knew it had because the litlte "CT" icon was next to my Minimap (right by the zoom buttons). This addon can be slightly confuseing, especialy to someone who has almost no clue what it can do (like myself). I was just happy that I got the addon to work, and I'm going to play around iwth it (I already have some).
I believe this method can work with most other addons, although some do require that you take out the Blizzard addons that come stock with the game. The CT addon that I have I know doesnt require you to gut the addon file, all I had to do was copy the contents of the CT_Core file to my addon file and I got it to work..
After 2 months of playing without any type of addon, let me say I'm pretty excited of seeing what this will do, since I've heard so much about the advantages. I hope this will help other Mac users who skim this site.
