Could You please make a .zip file version, because i can´t open the .rar file. I hope this isn´t impossible to do, and i hope that it doesn´t bother you ´:)
Hey! You can check 7zip as an alternative for WinRar!
R2 update is packed in .zip file, I hope that would help Mac users.
WOW, This Texture pack is amazing, you did some great work!
