Chosen Solution

Hey all, I recently received a friends old malfunctioning early 2011 macbook pro. Unfortunately, the issue seems to be a bad GPU. I have been able to boot into his old OS with the .kext GPU workaround but I would like to put in a new SSD and install Sierra onto that. The problem is that when I try to boot into the installer USB, the GPU problem is still present and I am not able to get into the GUI to install the OS. I am wondering if there is a similar workaround for a USB installer to be able to switch to the Intel GPU in order to install the OS. Does anyone know of a solution? Thanks!

  1. Pull the drive and use a SATA to USB adapter and hook it up to another Mac. Now download and install. gfxcard status https://gfx.io Open the program to make sure it is active. Hook up to the old machine and boot.
  2. If you don’t have access to another Mac, follow these instructions: http://dosdude1.com/gpudisable/
