So I downloaded the Sphax XmasBDCraft 128x texture and tried to open it, it opened but the terrain was all black, so it switched to a different one. I tried again the next day and it crashed I tried to open it so I could change it but it just crashed again. I can't get into the texture pack folder to change it and all the websites are for on windows computers and I don't have a windows computer I only have a Mac. I can't find it on Finder, and I can't open Minecraft. I tried redownloading Minecraft but it made no difference. I can't delete the folder and I haven't played Minecraft in ages!!! PLEASE HELP!
