The provided mac client linked on the website (The torrent with the file WoW_1.12.1_Mac.zip) doesn't work. It just says "The application 'WoW Classic.App' can't be opened". I know you guys don't do tech support for WoW or anything, but clearly this is a big issue. I doubt my mac is the problem. Anyone have any ideas on how to fix this? I'm currently downloading a separate Mac 1.12.1 from another torrent in hopes that one will work
