Hey everyone I I have been having some issues that I believe are caused by my gt 650m. I have a 2012 15 inch rMBP and i noticed an issue where the screen would randomly shut off. No matter how many times I turned it on and oft screen was black. The main reason I knew it was on was that the volume keys made sound when pressed. After waiting a bit the screen would always work again. One time when the screen was off I tried an option command pr reboot. After the reset the gt 650m was no longer detected. I tried a d boot and I could not find my network so I just restarted and the gt 650 m reappeared. With the reappearance came the black screen issues. I believe the gpu is dead or there is a driver error. TLDR: My computer is not finding my gt 650m. When it is found the screen goes black. Anyone else having issues with 2012 rMBPs? I have heard of apple Nvidia recalls in the past but not with this model.
