Temporary Fix Found:
I took the MCDJ root folder and put it in the resource packs folder, reloaded the resource packs and it works just fine!!! This is a Temporary fix I found.... every time I want to add more songs and all, I will need to make a new resource pack

So I'm using MCDJ on my Mid 2019 15 inch MacBook Pro, I was somehow able to set the MCDJ Root Folder and the custom discs show up in-game, but the name is not proper, there is no texture and there is no audio. The songs are in .ogg
