MacBook Pro 2012 broken GPU fix

I have a 17" 2011 MacBook Pro that suffers from the notorious GPU video failure (https://www.bit-tech.net/news/tech/laptops/apple-admits-gpu-design-flaw/1/)

Here is the work-around to turn off the GPU. Credit to PeytonPlaysMc

  1. Boot into Recovery Mode
    Hold Command+R+S keyboard buttons while pressing the power button
  2.  Disable System Integrity Protection (SIP)
     
    Type on the command prompt
    csrutil disable
  3. Reboot MacBook Pro into Single User mode
    Type on the command prompt
    reboot
    Then hold Command+S keyboard buttons
  4. Hard disk check
    Type on the command prompt
    /sbin/fsck -fy
  5. Mount root file system in read-write mode
    Type on the command prompt
    /sbin/mount -uw /
  6. Make a directory to save the AMD drivers
    Type on the command prompt
    mkdir /AMD_save
  7. Move AMD drivers to the save directory
    Type on the command prompt
    mv /System/Library/Extensions/AMD* /AMD_save
  8. Delete AMD driver cache
    Type on the command prompt
    rm -rf /System/Library/Caches/com.apple.kext.caches/
  9. Create AMD drive cache directory

    Type on the command prompt
    mkdir /System/Library/Caches/com.apple.kext.caches/
  10. Force refresh of drive cache
    Type on the command prompt
    touch /System/Library/Extensions/
  11. Reboot MacBook Pro to normal mode. Graphics will run slow at this point

    Type on the command prompt
    reboot
  12. Boot into Recovery Mode
    Restart MacBook Pro while holding Command+R+S
  13. Enable System Integrity Protection (SIP)
     
    Type on the command prompt
    csrutil enable
  14. Reboot MacBook Pro to normal mode.Type on the command prompt
    reboot
  15. Launch Terminal in UI and type
    sudo nvram fa4ce28d-b62f-4c99-9cc3-6815686e30f9:gpu-power-prefs=%01%00%00%00
  16. Restart MacBook Pro one final time
