Nostalrius Begins - Quality wow vanilla realm (1.12)

So, I'm new to Nostalrius after recommended from a friend, and I found a mac version of the supposed client: https://forum.nostalrius.org/viewtopic.php?f=32&t=1377

After the semi-struggle of downloading the file and extracting from the .zip, nothing was contained in the folder. Totally empty.

Are there any mac users, if any, that had this similar problem? If so, how was it fixed?

Despite being client for Emerald Dream, it works for all 1.12.1 clients, just need to change the realmlist ofcourse.
