Good day, My 15" 2011 MBP was one of those affected by Radeongate (the infamous Radeon GPU failure). Afaik, getting to the login screen requires the dGPU. Is there any way to get to the login screen by disabling the GPU? I know that the general gist is to boot into single-user mode and put the ATI/AMD kexts somewhere, but I don't know whether it's fully possible or not to get it booting this way. Thank you.
