Thank you everyone for your help with this, after scouring the mac forums I found someone who had this same issue. The fix was actually rather simple, just requiring I download classic wow first, then BC then WOTLK. So there is something up with the Mac Installer Client torrent [I believe that is how the patch files are downloaded?] that bugs out everything when you try to get all of WoW in one go. So I woke up this morning and started WotLK which is now sitting at 43%.

Thanks again,

Vasyl
