I downloaded the client via the Beginner's Guide (through the FAQ portion that lists Mac/Linux).
But I don't know where to go for my next step.
I don't have anything that says Nostalrius in the file. I have a background downloader, data folder, documentation folder, errors folder, eu patches folder, interface folder, logs folder, patch.html, patch.txt, realm list.wtf, WDB folder, World of Warcraft alias, World of Warcraft Install Log.html, WoW Classic App (I'm guessing this is where I need to go), WoW-1.12.0-enUS-patch (2).zip, and a Wow-1.12.0.559xxxxxxx-enUS-patch app.
I would just go ahead and mess with it, but I don't want to DL a patch or anything and screw the process. So looking for a little clarification.
