A video to show the visual error I am getting: I get this when I try to run forge mod loader. I have ABSOLUTELY NO MODS installed. I'm just trying to start it running in order to install mods. I get this screen. I can hear minecraft sounds in the background and it seems I can click on buttons on the menu, and even start up games, but I cannot see ANYTHING. Please help! On a mac OSX 10.8.5, I used the forge mod installer, and modloaders like 1.6.4 work, but not this one for some reason. I updated my Java to the latest version and I am still getting this error. Vanilla minecraft is working just fine.
