Wotlk update required...please help

I recently downloaded your WOTLK game to play on my mac and I have made an account but when I try to run the game a message appears and says...The developer of this app needs to update it to work with this version of macOS. Contact the developer for more information. is there an update i need to download for my mac?

First thing, check the realmlist.wtf file to ensure it's pointed at the warmane server. I think it's defaulted that way now, but no harm in checking. It should be "set realmlist logon.warmane.com"
