Minecraft Forums

I have a 2012 Mac Mini and I would like to use shaders. I am using Magic Launcher and minecraft Forge. I put the minecraft Forge in first and then the shaders. I then open Magic Launcher and everything is fine. But as soon as I open a world, magic launcher shuts down. Please help, here is the crash report:
