Shaders for mac

6 or so months ago I installed a shader and it worked really well. I installed it via opening my game files and replacing some delta files for each world. I got some new packs recently and I wanted to shade them, but now all the shaders around use Gshade and Reshade, and neither of them really work for mac or they require a really roundabout way of getting them to work. Does anyone remember the shader I'm talking about? I can't remember the name, but does anyone still make the shader this way?
