|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…

{{Faults
|Device=MacBook Pro
|Operating system=MacOS
|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.

Click on 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!
