Nostalrius Begins - Quality wow vanilla realm (1.12)

Hello everyone! I desperately want to play vanilla WoW, but I have a mac . I have tried really hard to download the file provided from google drive but am unable to fully download it for some reason. If someone would be so kind to help me out because I am not good with these things but really want to play. Thanks again!

When I try and open WoW classic, it goes to a blank screen . I deleted both the WTF and WDB folders and tried relaunching it but it still didn't work any advice?

Champ, you just downloaded the client didn't you? Have you altered the game data in any way yet?

Did you open up the realmlist.wtf file with simple text and change it's contents to say exactly this:

set realmlist login.nostalrius.org

yeah I did
