Resurrecting the Donated 2011 MacBook Pro (Bypassing AMD GPU)

[@Pantosoft]

michael should have at least 100k subs, his videos are useful, enjoyable and have clear instructions! Good job Michael, Subed to you since 2014!!! :D

[@MichaelMJD]

Thank you man! I appreciate you sticking around.

[@Pantosoft]

@@MichaelMJD:)

[@afarewelltokings]

He should have way more! I’ve been subbed for as long as I can remember.

[@Vicorcivius]

Ive been subbed to this dude for quite awhile. The reason he does not have a huge sub count is probably because the normal run of the mill moron out there is thinking that windows 10 and the latest hardware that comes out is the be all end all of computing. Even though its one of the worst os that is currently out. Windows 7 is far superior to windows 10 just in being stable.

I've been subed to him since like 2013 and am still following him since.

[@JohnHuxleySavage]

Incredible! My 2011 Mac Book Pro's third (or maybe 4th?) logic board just failed, and I was so close to giving up entirely on it, but the nvram command solution has worked.

[@NAMAHE]

[@DetikZainal]

Nathalie Hermansson 🤣🤣🤣 lol

[@emotionalintelligence776]

Not sure what happened in your case. However, I followed most of your vid before switching to dosdude instructions after your future self dropped in, lol. My goal was simple, disable the dGPU and install Catalina. After about an hour of multitasking, I was able to install the patched OS and have been enjoying my retired 2011 MBP which feels like a true MBP once again. Thank you immensely. I've waited over a year to finally do this. BTW looking at your procedure it's one step different from what I did. As I intended to install the Catalina OS, I made an OS bootloader for it. After using S mode initially for the prefs you described, that was the only time I needed it. I disabled csrutil from the Recovery via the USB bootloader as I did get the enabled SIP error. Since I was not sure why it wasn't disabled I rebooted into the USB bootloader and ran the terminal command from that. Once I rebooted everything was green and I ran the program without further issue.

[@amdintelxsniperx]

just to add to this video in case anyone stops by . we all know the intel hd gpu is kinda puny but there is a way to increase its performance . if you have a 2.2 or 2.4 you can install 1866 mhm ddr3l and the chipset will happily run them at full speed you can also use 1600 the ogpu will use the system ram as gpu memory up to 512 mb the faster ram will help a lot in many tasks

[@crashbandicoot4everr]

When you delete or modify kexts, you have to rebuild the kernel/kext cache after doing so. To do that, you have to run this command in Terminal: sudo kextcache -i /Volumes/YourPartitionName Glad you got it working! :)

[@MichaelMJD]

Thanks for the info!

[@abyssstrider2547]

For a second there I thought you had mispelled text

[@abbeygallepersonal]

The Dosdude1's Guide worked for me, the first time I tried after the software did its thing and it asked me to restart it happened again and had to do all over again but it seems that the second time I did it it's now working. Hopefully it won't boot up using that damage GPU but if it does it's not that hard to boot using this method. Thanks so much!

[@dosdude1]

Huh, I'm not sure why the tool is still detecting that SIP is enabled, after disabling it in Recovery Mode... Try running "csrutil status" in Terminal and see what the output says. If that reports it's disabled, there may be an issue with the tool that I need to fix.

[@MichaelMJD]

Hey Collin! I have a follow-up video in the works where I was able to get your tool to work. As some have pointed out, I think it might have something to do with the multiple OS partitions that I had installed on that HDD. After I did a clean install of macOS on a new drive it worked perfectly.

[@andusensei]

I'd try doing a completely fresh install with a single partition.

[@afarewelltokings]

I have never heard you get mad in a video until today and frankly I’m impressed

[@markconger8049]

I contacted Rossmann Group in New York about repairing this at the board level and their response was it isn’t possible to just replace the GPU. They ahd tried it but machines were dying again within days. They pointed me to dosdude1’s method of flashing the firmware to permanently disable the GPU and enable Intel HD graphics. COVID has stepped on that project if you want to mail in the computer for them to fix. Doing it myself isn’t possible at this time. So, for now we are going to replace the 2011 Macbook with a different model that is newer and get by for now while we transition AWAY from Apple altogether because enough is enough. Apple is no longer the same company it was ten years ago. I’m done.

[@Ryan_Revier]

You could upgrade the macos in it since Catalina is on older macos, but OCLP Big Sur could do fine in it..👍🏻👍🏻

[@josepintor8986]

This did it for me! I have been working on a mid 2010 Mac for days! It is now installing! THANK YOU!

Thank you thank you again!!!

[@dylanlindsay1993]

hey mjdi just boUGHT A 2011 MBP WITH FAILED GPU ON PURPOSE!!...... n i am doing this mod right now! n so far it worked! the laptop was 40$ and my 2013 mbp died so i did this rather than fixing it... update: it took two hours but i did get the bypass to work! i had to stick the ssd in another mac just like you did in the video but in the end everything worked out! FYI if you use dosdude1s catalina patcher to upgrade from 10.13 high sierra to 10.15 catalina the brightness control will work again without having to do that hardware mod!

[@mustafatekbas1132]

Great video man. I followed the steps on the website and 100% works. I had no issues like you had. Thanks 🙂

[@MichaelMJD]

Awesome!

[@TheAdagioSostenutto]

Thanks for your video. The method worked perfectly on my MacBook Pro late 2011. The gDPU disabled also worked fine. Thanks again.

[@nicolasgimenez7607]

The best video in the site! Worked perfectly fine. Late 2011 MacBook Pro. Thank you!!

[@XGempler]

When you issued the CSRUTIL DISABLE command in single user mode (black/white text screen) it clearly stated "THIS TOOL NEEDS TO BE EXECUTED FROM THE RECOVERY OS". instead of swaping drives like yo udid you could have restarted in recovery mode (Control+R) then selected Tools-Terminal Mode and then typed CSRUTIL DISABLE... then restart in single user mode again to issue your move command.

[@michaeljones3687]

Since the drive has multiple partitions, it may be causing a possible conflict with disabling the SIP?

[@SenileOtaku]

That was my thought. It might be disabling it on a different system partition/folder than it's booting from.

[@atarixle]

I'd like to know if this helped or not ... I mean just in case I ever buy a Mac again (which I promised to my Girlfriend I don't since I got me like 15 classic Mac Laptops the last two years)@@SenileOtaku

[@TrialMacameau]

Mike, you have multiple partitions hence you have 2 OSx's hence you have to full reinstall the system

[@MichaelMJD]

Going to try this out in a future video!

[@dexteroreilly]

Hey @Michael MJD - you weren’t booting into Recovery mode which is why CSRUTIL didn’t work. You need to hold down the Command-R keys and hold them during boot. It’ll launch the recovery image and give you access to Terminal.

[@dexteroreilly]

@@rhuephus single user mode isn’t required to disable CSRUTIL. You just need access to the Terminal program provided by the recovery partition.

[@drobinson772]

I can't believe this worked! I've tried everything and this was easy. Thank you. Thank you. Thank you.

[@Mateo-ko9kx]

Afterwards, you probably noticed the lack of brightness adjustment capability. Use Shady app for that purpose.

[@TRENX_]

I think it’s not disabling the sip due to the multiple partitions? Not too sure.

[@notvitalkanev]

9:56 maybe there are some ATI* files left in Extensions folder?

[@RetroReviewYT]

I’d recommend dosdude1’s custom firmware for the gMux chip when it releases for a permanent fix. He’ll be selling a flasher that end users can use to flash the CFW for the IC chip which won’t require any modifications to use.

[@inwerp]

Fingers crossed. However flasher will not be cheap and it makes sense only for repair services. I also tried to read chips firmware but so far i had no luck.

[@SenileOtaku]

Funny to see those particular machines together. Right now in my office I have my mid-2010 MBP sitting right next to an Inspiron 6000 (looks exactly like your 6400). I was planning to use the Inspiron as a ReactOS test platform. The MBP works perfectly (as far as I can tell), so I'll be bumping up the memory and switching to an SSD eventually. Nice and clean inside and out (the power brick was dirtier than the machine). The MBP at first didn't seem like it was taking a charge (which wouldn't have been a problem for my usage), but once I wiped the partition table and (eventually) got it to pull an installation off the internet, charging works fine. I've seen something about some reset that sometimes needs to be done when the charging acts up, it probably had something to do with the system files (which, obviously, were gone by then). Did the disk wipe by booting a Linux Mint DVD and running "dd if=/dev/zero of=/dev/sda bs=1M count=100".

[@brainndamage]

Count=100 only wipes the first 100 sectors (51.2k). A better way is to use hdparm --security-erase if the drive supports it (most do) and it's not locked (sometimes the bios locks it and the drive needs a power cycle after booting). This is also much safer for SSDs as it only wipes the encryption key instead of increasing the write count on the flash cells.

[@IngwiePhoenix_nb]

Here are a few things I noticed: - You removed the kext files - but did NOT rebuild the kext cache. - In your "mv" command, you typed "/DisabledExtensions" - but, you didn't add a slash :) Should've been something like $ mv AMD*.kext /DisabledExtensions/ - Are you sure that you _really_ disabled System Integrity? :) Perform as root, via recovery. In Recovery+Single User mode, you should be root, but type: "echo $USER" to see if you are, or are not root. - Also - for safety, make sure that you boot into the proper recovery drive, so that it will also disable system integrity on the proper partition. If you are using two different components, OS and recovery, it might fail. Use "diskutil list" to check which drives are currently mounted. Also, if you enabled system integrity with this HDD on a different mac, disable it first, then re-enable it, in order to get a fresh startover. But other than that, nice video!

[@blkhorse70]

Thanks a lot, u made my Macbook back to life in a simple, short and easy steps

[@MichaelMJD]

Glad to hear that!

[@JoshAnimatesGacha]

Hmmm- right before it hits that great screen spam the side cart button or the brightness buttons and it should boot up slowly.

[@KennethPlaysOfficial]

i have a 2012 macbook that will crash once switching to the nvidia gpu. will this method work for me?

[@wantikjasonchiu4711]

it seems to be that it in a possible way to run recovery from the el capitan partition, because you would have applied the system integrity check in the situation that the partition for it that way.

[@encinobalboa]

Somebody on YT successfully baked the entire logic board from his Mid 2011 MBP 15. It was a similar bake process as used on the AMD 6970M GPU in Mid 2011 iMac 17 inchers. The youtuber set temp at 370 and baked for 7 minutes. 6970M bake is at 390F for 10 minutes.

[@encinobalboa]

To follow up on this, I just picked up a MBP 17 with no chime and black screen. Intel GPU was not initializing. Took the logic board out and applied heat gun to the top of chip. It's working again. How long it works is anyone's guess but it is not a brick anymore.

[@13leafs]

@@encinobalboa It's only temporary. Been down that road.

[@Buzzhumma]

@@encinobalboa i gonna try on mine . the fan spin and stops on off on off on off. Did yours spin

[@encinobalboa]

@@Buzzhumma Look for a boot sequence chart. That will give clue where to look. Fan sounds like a low level failure which is not so easy as GPU bake. Maybe some heat gun on CPU or a MB controller might bring it back. Worth a last gasp as 2011 is not worth paying for tech fix.

[@wutangcatclan]

Picked up a Late 2011 17 inch for $25 with GPU issues. Resurrected it, it was amazing ^^

[@edwardtam8623]

The tools worked. It saves my computer. Many many thankssssss

[@ZardozBeats]

Thanks for the video! Would you also know how to re-enable the GPU? (for example when a new motherboard is placed)

[@MarcCardwell]

Hmm. My late 2011 MBP just died. Boots into safe, but not recovery or internet recovery. I just saw a CL post selling the same model and dude said he disabled the AMD chip, I googled it and here I am. I used my Mac with an Apple Cinema Display, but if this works, cool. Thanks for posting this vid!

[@deathbringer2000]

Yo @MichaelMJD, If you still have this machine, I figured out a method of getting it to boot without moving kexts or anything. There's am NVRAM variable called GfxMode that sets what GPU to use on boot. If you set it to 4, it powers down the dedicated graphics and exclusively uses the integrated graphics. This even sticks between updates, and even entire OS reinstalls.

[@mnisiide]

Hi… could you point me to where can I get more details on that solution?

[@BrianEller-begrafx]

One question: I'd heard from other sources that when the AMD GPU is disabled (by whatever method) that you can no longer use an external monitor. Can you confirm/deny this, when using the method you've used?

[@Haroflowks]

yes, that's right!

[@AaronWelchMusic]

Hi Mike, I got the disabler to run! You need to do the single user code, terminal the shorter bit, then reboot by typing reboot into the terminal after, and it'll reboot very quickly, take a while to boot up, maybe do a few cycles, and when I got on, the intergraty protection was disabled and it ran!

[@davewills6121]

Good informative vid, handy to see problem solving and workarounds being practiced. Don't get me wrong, i like it easy, but if all goes well in the end...Gold. PS: is this at all reversable?, just like to know. Regards.

[@etsakodeejaystarboyavevo]

I was trying to make an upgrade and since then my Mac only make the Mac sound and show logo then get stuck there could this be the solution ?

[@AnastasiosAPapanastasiou]

I have the same issue (as most with MBP 2009-2012). The only thing I do and seems to be working for me is I boot in single user mode (CMD+S) and I enter the command: sudo nvram fa4ce28d-b62f-4c99-9cc3-6815686e30f9:gpu-power-prefs=%01%00%00%00 Everything runs smoothly but if you restart the machine you need to do all the steps again. So now I’m doing it al least day after day

[@bananaorangeguy5277]

this happen to me, I am glad my mbp is booting, but when I restart the machine i need to do all the steps again, is there new solution?

[@closencounter1000]

It worked for me. I was seeing pink lines the browsers weren't working right. Now I am watching a 4K movie.

[@closencounter1000]

I have the same problem bro, my MB Pro 17 early 2011 is one year now doing this. I'm not sure if we have to disable the GPU or not. did you fixed your? thanks and if yes please share the solution

Worked perfect for me!!! My MacBook is alive again!!!

[@MichaelMJD]

[@payday1963]

I see that dosdude1 has another option that requires opening the case and soldering wires etc, is that a better option? He sells a key for $20. I just did the command prompt version and it worked fine. Whats the difference??

[@jacobisnotcool1714]

This worked great for me. I followed the directions from dosdude1’s guide and ran the program. The only question I have is that prior to finding this guide I was using a fan control program that made my fans run on 100% to keep the video card cool so the MacBook wouldn’t act up, and I’m wondering if I’ll still need that at all? I’d imagine not, but out of curiosity I feel like it would be appropriate to ask.
