Nostalrius Begins - Quality wow vanilla realm (1.12)

Hey guys!

I've just downloaded the client from this link:

https://mega.nz/#!2hBATAoY!D99CC3KKUbtw ... E9o-aAw-EE

Once it finished downloading, a .zip file was added to my downloads folder.

I then opened it, and the .zip file is now a document called:

"World of Warcraft 1.12.1 OSX 2".

The folder contains:
Background Downloader
Data
Documentation
ERrors
EU patches
Interface
Logs
Patch.html
Patch.txt
Realmlist.wtf
WDB (in here is WoW Classic)
WoW-1.12.0-enUS-patch
WTF


When I try to launch the "WoW Classic" file, it opens, then after 5-10 sec, it replies that "World of Warcraft was terminated unexpected"

Can anyone help me what I am doing wrong? I am new on mac

Thanks in advance!
