I've recently rebuild shaders for my program and it stopped working ( black screen ) on OS X ( El Capitan ), but it's ok on Linux on GTX 660.I've tested it on another Apple hardware and it worked on OS X on R9 395 ( but super slow, because of double ). So I suppose it's problem with my Intel HD Graphics 5000.There are no shader compilation errors, and here is my shader code:https://github.com/Marqin/YuriaViewer/blob/4241e384da0f27d26cbf5557518db905a9d40039/vertex.glslKeep in mind that this software worked on El Capitan with OpenGL 4.1 before shader rewrite. Here are my glfw hints:glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 4);glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 1);glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);glfwWindowHint(GLFW_OPENGL_FORWARD_COMPAT, GL_TRUE);My program also is checking for GL_ARB_gpu_shader_fp64 and it's available on my Macbook ( Macbook Air 2013 mid ).I've debugged it a little and it looks that i is always lesser than vis on OS X, that's why it's black.I've also made a simple test - I've typed all uniform values in shader by hand and now it wasn't black, but I've got some gibberish on screen. Then I've changed every dvec3 and dvec2 to float versions and it showed nice fractal. So it looks like double is not working on OS X. But how can it be? It's saying that GL_ARB_gpu_shader_fp64 is available and it even doesn't complain when I request it in vertex shader.How can I make it work on OS X Macbook?
How to make double working in OpenGL 4.1 on OS X ( Intel HD Graphics 5000 )?
