Hi all,

I have been running this patch for some years now on my 8.2 Macbook Pro. Since it's stuck with HS I was thinking about installing Ubuntu on it. My question is, would it work ? I believe that the BIOS part would, but I dont think the running portion of it would.

Have someone tried it successfully ?

Many thanks

Hello everyone, i have spent a ******** of time reading through here and looking online now, but i have a very weird macbook 2011 17 inch that just can't keep the nvram power pref parameter. The -v stays on, but the igpu will just stick if i reboot the machine from terminal - if i ever shut down, i need to go back to verbose and run the command again, type reboot, then i get one "good" boot and that's all. Battery holds the charge no issue - i can repeat the full procedure while running on battery or attached to wall, all the same :(
Anyone had this same experience before? Will purchasing a demux from dosdude fix it?

Fully restored display on High Sierra 10.12.6. Sleep/Brightness controls fully functional thanks to stecker870's patched AppleGraphicsControl.kext. See link below:

Is there an updated version of this kext that works on Big Sur/Monterey?

Why are you answering a Russian in machine-written Ukrainian? There's enough Russian speakers here to make it not such a problem that there is an occasional post in Russian. The poster will have to wait longer for an answer, though, that's for sure.

Откатился на High Sierra, проблема не ушла, потом откатился на El Capitan, сначала проблем не было, а потом снова появляется черный экран, только ведет себя совсем по другому, например шапки не выглядят загорится, и вы можете включить его сразу, не дожидаясь охлаждения, как если бы возникла новая проблема.

It's possible to disable the dedicated GPU (Radeon 6750/6770) via software. I recently did so when I wanted to upgrade to Mojave. gfxCardStatus was no longer reliable for turning off the dedicated GPU so after a bad experience with dosdude1's script. His Mojave upgrade script for unsupported Macs is great but the disable dedicated GPU script leaves a lot to be desired, as it leaves the Radeon 6770 running at full power and burning itself out if it's still working as mine is. dosdude1 has a conflict of interest here as he's selling hardware solutions). I can vouch for Luis Puerto's post Disconnecting the dGPU in a late 2011 MacBook Pro.

Basically disable SIP and then run this command in terminal to set an NVRAM variable:

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

The full solution includes much more detail and is beautifully presented. Luis's solution does not involve Linux, EFI firmware, hardware mods and is totally reversible. There are built-in failsafes in case the NVRAM variable doesn't hold. It also powers off the discrete GPU. Automated Apple system upgrades are even possible with a little preparation.

Luis's solution should be the one recommended at the start of this thread @AppleMacFinder. I see you have it buried somewhere in the middle but it would be best to put it at the top and perhaps with a link to Luis's post as the presentation there is particularly visually clear (those virtual terminal windows are nifty).

PS. I see you take the same exception to dosdude1's script to disable the internal GPU as I do (having tried it and ended up with a very hot MBP 2011). Thanks for starting so many people down the right path with their MBP 2011.

Hi there,
my situation right now with my macbook pro 2011 late is I've to update from 10.10 to 10.13 because Yosemite is expired certificate after 30 September 2021. But i afraid some problem will happen with my Macbook, at this moment i'd disable my Graphic card by these command:

nvram fa4ce28d-b62f......gpu-power-pr-efs=%01%00%00%00
nvram boot=args="=v"

Is there any problem if i update my macOs to 10.13.6 ? (i've High Sierra install package on my Application but afraid problem will happen after use it)

Thank you alot for reading!

Why will you disable the GPU? High Sierra is supported. However, it´s out of support.

I am Ukrainian. I don’t speak Russian for my reasons not to disclose here.

Then it´s about to die. There´s no risk on that command. But if for any reason the PRAM is reset, you will have to introduce it again. I really recommend you Demux.

My recommendation - 2012 or 2015 MacBook Pro. Forget the 2011 !
Maybe, equally my own 2011 15" MBP has never given any trouble seeing off the 2012 Retina which is now in the junk pile...
Screen Shot 2021-09-28 at 03.21.23.png

Remains to be 100% stock, never clean installed unsure what to do with it. Recently it's been standing in as the HTPC due to the 2014 13" MBP going haywire.

I had a 2011 also. Never an issue either, but many tell to me it’s bad machine - I get rid of it and buy 2015. I too have 2012 non-retina.

2011 15" is a problematic notebook, equally sometimes you get lucky. If this MacBook Pro was going to burnout it's dGPU it would have done so way before the 5 year mark as it's been hard used. As it stands I do limit the dGPU's usage, however it remains to be fully functional and engages as and when required.

Ironically I kept the 2011 15" in the family as I didn't want to dump a known "lemon" on someone unsuspecting. Passing it on to my wife and then my daughter, returning back to me in an unbootable state, left for dead in a box for a year and a half. After some determination and a lot of cleaning up of the software image it remains to be completely stock barring OS updates. Cant complain as more than had my money's worth out of it... :apple:

I only want to know is there’re any troubles happen if i update from mac 10.10 to 10.13 on my “dead gpu = already disable it”.

I am not say that all 2011 bad, but most were you and I are lucky ones here :)
Very true as the majority of the 2011 15" MBP's failed. I rather think that my 2011 15" is more the exception than the rule. This one has run for days on end at full tilt running engineering simulations with no concern for the hardware. Now retired and back with me the 2011 still serves purpose from time to time.

Don't know, I do know that OSX 10.13 runs very well on my 2011 15" MBP and I mostly force the dGPU to be off. What I think is that you will need to disable the dGPU once again in software as the OS upgrade will reset all such parameters.
