That *&*%@?!5 GPU card!!!

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…

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

nvram fa4ce28d-b62f-4c99-9cc3-6815686e30f9:gpu-power-prefs=%01%00%00%00

Reboot. On the reboot, hold down command and R when you boot the machine up, let go when you get the Apple logo.

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:

diskutil cs list

diskutil coreStorage unlockVolume UUID

Now, we all need to do the following, run the command:

cd /Volumes/Macintosh\ HD

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:

mkdir AMD_Kexts

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:

mv System/Library/Extensions/AMD*.* 12Jun21AMD_Kexts/

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!

MacBook Pro – finally, it is working!

But the question is, will it reboot OK. It did. So I will shut down and leave it and take back to the owner tomorrow. I think if it keeps doing it I will suggest he buys a new one, it is 10 years old now.
