There are a few utilities to get around that, so I can live with that.

There was a major flaw in the AMD Radeon GPUs included with that model years logic board which seemed to cause GPU failure either due to overheating, internal chip problems, BGA solder joints getting broken, or a combination of the above.

The problem was so rampant, Apple was forced to set up a free repair program for affected MacBook Pros though the 2011 model has since been dropped from that program.

Ive handled three 2011 MacBook Pros (none of them my ownI had an Air back then), and all three of them were scrapped because of the GPU issue.

First off, it was using a slow 5200 RPM hard disk; after replacing that with a nice, fast SSD, and ensuring she had 8 GB of RAM in the laptop, I was pretty pleased with my work, and was about to shut down the laptop and send it on its way.

Ten minutes later, still a grey screenand the fans are spinning madly.

Not good.

I didnt see anything obviously wrong, but knowing from past experience that problems usually surface only when the GPURadeon.kext files (Kernel Extensions) are loaded.

Single user mode proved disk, RAM, CPU, and even integrated graphics were okay.

But this time it would reboot itself within a minute or so, so that was different Alas, after hacking around a bit more with System Integrity Protection disabled, the reboot cycle eventually became quite short indeed.

Touch the tip of the iron to each metal side of the resistor (where the joints are), alternating one side to the other for about 1-2 seconds each, until you notice the resistor starts to become free from the logic board.

And if youre like me, you might shoot the little resistor a few inches across the logic board Just be sure to do the following after it comes off.

If there are, heat the pads with the iron tip until you can wick away the solder a little.

Hopefully you can just lift the bottom-cover-less laptop, turn it over, and you see a tiny black speck fall to you work surface.

And realize there are thousands of these things soldered to the logic board.

The resistor is small enough I cant pick it up with my fingersor even a standard needle-nose pliers.

After removing the resistor, be very careful when upgrading the OS or making other major changes (be sure to keep current backups).

And, as suggested by RMM, try to avoid resetting the NVRAM, just in case that makes things go a bit south.

Im not talented enough to do this procedure myself, but someone savvy generously accepted to try it for me.

Its been almost a week since the hack and everything works perfectly.

Only thing: my external monitor (minidisplay) stopped working.

Do you know if anyone had the same issue Is their a fix (or is it the price to pay to kill the Radeon beast) Best.

Anyway, its way better to have a working Macbook (with pretty decent performances given its age) without external display than a very expensive flat grey desk lamp turning on and off.

I dont have the ability to do this type of work but found someone in Melbourne (about 5.5 hours drive from me) who does this.

Naturally, with the choice of a dead MacBook Pro or a working one but minus a working external display port, I chose to go ahead.
