I've been trying to download shaders for my Macbook Air (I know I know, I mainly use Windows but just wanted to have some lite shaders on this computer for when I'm traveling), but when I download them they seem to download as a folder rather than a zip file the way the would for me ordinarily when I download them on my PC. I attached a picture of how they look when expanded in my Shaders folder, and how it appears on the download list (the Shaders 1 and 2 folders are the two Sildur's shaders I attempted to download. I'm used to them appearing as the name of the shader in downloads, which was also weird). When I open the game they don't appear under Shaders in Optifine. Any suggestions are appreciated. Thank you!
