Permanently Disabling 2011 MacBook Pro 15" Dedicated GPU - Custom gMux Firmware Flashing Overview

Huge thank you! I am very glad I found your channel. My early 2011 MPB suffered GPU failure a few days ago and I've been trying to figure out what to replace it with. I don't like the post 2016 models with the touch bar, everything soldered on, and keyboard failures. I've been thinking about trying to get a 2015, but your software solution saved this machine. I'll use it for a bit before I decide if I need to flash the MUX firmware or not. Thanks again!

[@bigdarryld]

Here because of Louis Rossman video. Will be keeping an eye out for your pogo pin solution can't see myself doing the soldering. I could never get the nvram command solution to work so I used a USB stick with Arch Linux to modify the EFI which I think does the same thing as the nvram command. My brightness controls and sleep capabilities have always worked. With this solution does Thunderbolt still work. Thunderbolt doesn't work on my system and I think it's because it's tied to the dedicated AMD chip. Thanx for the work you've put into this.

How do you fix a computer that boots up normally but after sometime it will glitches and have lines scattered through the whole screen then shuts down after that?

[@MrDazzathedude]

this should be able to fix that problem, the glitches are likely the and gpu which this disables so you use the built in graphics only. the GPU on these machines will ALWAYS die at some point so to disable it is only a good idea?

[@rhuephus]

@@MrDazzathedude "Built-in" ??? Both GPUs are soldered (built-in). The AMD GPU is on the same die as the Intel CPU - which is a faulty design. The Intel GPU is actually soldered to the motherboard (or logic board) by itself.

[@deasystems]

@@rhuephus : That is incorrect. The Intel integrated graphics unit is *part of* the Intel CPU chip itself. The AMD GPU is a physically separate chip soldered onto the motherboard.

Will be fixing a lot more now that this is possible. these mbp 15 2011,s really hold there value after all these years. just pop 16gb ram and 1tb ssd in w a brand new battery and a usb to hdmi for external display at 4k and it will be good for another 10 years. Greaty EDIT: I also tried this on a 17 inch early 2011 2.3ghz and it works fine. same results from the 15" great!!! the hd graphics 3000 w 512mb ram is not a bad card it can handle Mac OS and its not to bad so were really not missing out on much its just like the 13 inch 2011 no graphics card.. this is a breakthrough in Mac repair!!!!!!!!!

Nice work and thanks for the reminder that the AMD chips are actually dead and it's not a soldering issue. There are way too many people who don't believe it (and I guess never will), including people who do dozens of reball a month. :(

Yep... I don't understand how some people still think it's a soldering issue... Common sense would tell you that that cannot possibly be the case.

[@RetroTechMuseum]

@@dosdude1 well my macbook pro's would not boot at all, until I heated the video chip to melt the solder. I am guessing that's why people think its a soldering issue. After that I applied your GPU Disable mod from your website and good so far. Can't wait for your new firmware for a permanent fix!

[@NicVandEmZ]

dosdude1 wish there way to this with a mid 2011 iMac That Geekbench say Is a AMD Radeon HD 6750M 512 MB but it also says intel graphics Hd 3000

[@piernov]

​@@RetroTechMuseum no need to melt the solder. The chip will react to heat, 200°C is more than enough (even though it's way too low to melt the lead-free solder). This will make it work for a couple days/weeks/months and it will fail again shortly, that's why people think reflow or reball actually fixes it which is entirely false.

[@piernov]

@UCaCeg-CLR0XH8aE9eGeoi_w No way for it to work on iMac. The LCD connector is routed directly to the MXM port to the graphics card. The iGPU is not used at all. There is no solution for this iMac, all the graphics card that are compatible with it are dead. Only thing you can do is put an NVidia card like GTX765M, you lose bootscreen, brightness adjustment and external display support and you have to grind down the heatsink for the inductors of the card to fit. But at least, you get a display in macOS…
