The problem:
The MacBook Pro with the dodgy GPU, well, it decided to update itself again, with meant it wouldn’t boot. I did have a look online to see if there was a permanent fix, the only way to do that was to do something with a soldering iron, I thought it was best to steer clear of that. I did train in electronics, but I am rubbish when it comes to physical practical stuff. I would prefer if it could be done programmatically. This time I missed a few parts. In total, it only took about five minutes to fix it. So how did I do it I hear you cry, good question, here is the answer…

Device:

Operating system:

Software:

Guidance:
If you having problems seeing the screen, boot into single user mode but holding down command and S when you boot the machine up. Run<blockquote>nvram fa4ce28d-b62f-4c99-9cc3-6815686e30f9:gpu-power-prefs=%01%00%00%00</blockquote>Reboot. On the reboot, hold down command and R when you boot the machine up, let go when you get the Apple logo. [[File:MacOS recovery utilities.png\|alt=MacOS recovery utilities\|none\|thumb\|800x800px\|MacOS recovery utilities]] Click on utilities and terminal: [[File:MacOS utilities for terminal.png\|alt=MacOS recovery, select utilities and terminal\|none\|thumb\|800x800px\|MacOS recovery, select utilities and terminal]] If you have more than one partition run the following lines, if you only have one partition you can skip this bit, but we need to find the UUID:<blockquote>diskutil cs listdiskutil coreStorage unlockVolume UUID</blockquote>Now, we all need to do the following, run the command:<blockquote>cd /Volumes/Macintosh\ HD</blockquote> [[File:MacOS Terminal with command.png\|alt=MacOS terminal\|none\|thumb\|800x800px\|MacOS terminal change the directory location]] Now, we need to remove the AMD Kexts, first create a directory where we can stick them on the off chance you need them in the future using the line:<blockquote>mkdir AMD_Kexts</blockquote>Because I had done this a few times, I have now started to create the directory on the date, so this one I called 12Jun21_AMD_KEXTS Now, lets move those AMD Kexts:<blockquote>mv System/Library/Extensions/AMD. 12Jun21AMD_Kexts/</blockquote>then type in reboot: reboot In theory, if you have done everything correctly, you should now have a working MacBook Pro. I booted, and it worked! [[File:MacBook Pro working.png\|alt=MacBook Pro now boots\|none\|thumb\|800x800px\|MacBook Pro now boots]]
