Well... when you did the EFI-Mod and removed the resistor, it even stands a reinstall or upgrade. Only a Pram-Reset will result in a black screen.

Well... when you did the EFI-Mod and removed the resistor, it even stands a reinstall or upgrade. Only a Pram-Reset will result in a black screen.
And that will be catastrophic for most users. This resistor mod is not very recommendable for this reason.
But the way out of this mess then should be always mentioned when arguing pro-resistor-removal:
In case the resistor is gone and the NVRAM cleared:
be sure that you had remote-login enabled!
Then connect via ssh and issue the nvram changes from there and reboot.
I did not test it. But it might help.

[GUIDE] keeping iGPU activated when booting into Windows using apple_set_os.efi
https://egpu.io/forums/pc-setup/how...ctivated-when-booting-into-windows-boot-camp/
apple_set_os.efi
Tiny EFI program for unlocking the Intel IGD on the Macbook Pro 11,3 for Linux and Windows.
It has been made to be easily chainloaded by unmodified EFI bootloader like Grub, rEFInd etc.
Perhaps it could be possible to solder a tiny on/off button instead of this resistor - or, if it is too large, maybe solder two tiny wires and this button in the middle (of course with insulating the metal conductive parts and solder joints, because this "adapter" would be touching a motherboard when assembled)
Using the CMIzapper Tiresias you get the best of both worlds.
The modified Mac become PRAM zap resistant. You can clear the PRAM to your hearts delight and the iGPU will remain active. And with the new version you even have the option to solder two extra wires and have brightness control in High Sierra, or any other OS.

Great find, but I think that 59 euro is a bit expensive for a tiny board with a chip which costs about 1 usd. Perhaps I'll wait for some cheap chinese clone to appear, e.g. at AliExpress
I made the switch over to Linux Mint, and couldn't be happier. My MBP can do more now than it ever could do. It's been a while since I've used Linux, but have always liked it. Linux Mint is the best version I have ever used. The idea of using macOS or Windows makes me want to barf now.
If you're not using Linux, you are wasting your time and cutting your productivity drastically. Seriously, I can't go back. It does everything you always wish your computer would/should do plus stuff you never thought it could do.

I used your simplest way and it worked to get my booted... when it boots ...it goes to a black screen and shows everything happening to boot up. Then the splash screen with photo of flamingos comes up and slowly.... VERY Slowly... everything comes up. But I am having a problem with my cursor for some reason... it works for about a minute then it disappears altogether so I have to force shutdown using the power button and the reboot again. Can you give me any advice about why this is happening. I am so thankful that your method worked to get my computer booted. Everything shows. But suddenly my cursor stops and disappears completely leaving me helpless to open any files.
THANKS SO MUCH FOR WHAT YOU HAVE HELPED ME DO. ANOTHER QUESTION WOULD BE:
If I cannot get the cursor working how can I transfer some things from my old computer to my new one.
Also my computer first scans iTunes and then tells me my iCloud session has expired...I never used it to my knowledge ...I just used my old version of iTunes. The thing is I did have the Apple store upgrade my software to OS X from Lion... so is that complicating things for me with regards to this insistence on iCloud?
my email is emccready@yahoo.com and I would appreciate hearing what you have to say...this solution is incredible!!!

Or try the simplest way - No needed ArchLinux - Only MacOS:
1 - Boot Single User (press Command + S) at boot (If you have MacOS installed on your hard drive).
Enter these commands (change gpu-power-prefs to Intel GPU and boot verbose):

rebootHave you tried using the USB mouse? And is your computer "frozen", or after this cursor problem you could still use a keyboard - e.g. to open a command line, cd to a directory with files and scp - copy them over the network to another computer, preferably not-Windows (but it is also possible to install a ssh server on Windows PC, to ensure that you could copy the files to it over the network using this method. E.g. Bitwise SSH server)
Re my cursor... I finally somehow got it working. Maybe because I reset the NVRAM doing Command Option P R several times which (stupid me!) surprised me by reversing the fix your formula did and I was not able to reboot. So I just followed the instructions again and it came up.... and this time the cursor worked as I tried various programs to open... it does seem however that everything is much slower to open .... is it because I had them update from Lion to Yosemite X?? I thought these newer systems automatically worked faster. That is not the case...it takes forever even to open the little About this Mac window!.... I wish I had never asked them to update because it worked faster then. Or is it because of the change I just made to boot up successfully? One thing I wish I could do is bring all the Calendar information from my old version to my new version of Calendar which is using High Sierra. I wish Apple would stop breaking things when they work just fine.... too many idle hands around changing things just for the sake of change is very irritating. I don't like the way my iTunes appears and works under the new system. I liked things the way they were in Lion and I could miniaturize the display to show the tiny rectangle with basic information.
Anyway...I am just soo very happy to have been able to get the old computer working because there is lots on it I cannot bring to my MacBook Air (the old one is a MacBook Pro of course with 800 gigs.) I am disgusted that when I had to buy this new one, in Thailand, they did not have a 1 Terabyte in the shop and it would have taken weeks to arrive from Singapore...so I bought the cheapest (still about $500 more) that is limited FOREVER to 256 gigs which are almost used up already! Apple has gotten stingy with storage which is really so cheap now. I also resent the fact that there are only 2 openings on the side for the new usb and I had to buy not only two peripherals with the older connections, but also a CD/DVD Writer and a 2 Terabyte hard disk which added another $250 in additional expense plus the need to have more desk space for all that crap which is included in my old MacBook Air. I was disgusted to learn I could not add more storage.... what the hell is that about???!!! disgusting because I would have wanted to add more later. I cannot put my music on this new Air because I have about 132 gigs of music alone! Anyone else upset about these things in the new stuff? Be sure to get the most storage you can order because it is set in stone. Also why is their storage so damned expensive! Sorry to belly ache!
THANKS TO YOU ONCE MORE!

I noticed this behavior on my MBP too, that is was just sluggish when booting and that some programs loaded much slower. The interesting thing is that before doing the workaround I checked Apple's official hardware testing program, and it said everything was working perfectly, Clearly my screen was all garbled up though with lines going across it.
This has all changed since switching to Linux Mint. My computer boots fast, and all programs are very fast and responsive. I've noticed some odd log entries having to do with the "failed" AMD GPU. More and more I'm being led to the conclusion that all these problems were specifically created by Apple through their software updates, in order to cripple older MBP's so that people would toss them and buy new computers. Their own hardware tester says my computer has zero problems. All that leaves is a software issue. The GPU software and NVRAM settings are controlled by Apple.
I did a software update and I'm surprised it was only a minor annoyance. I only had to catch one reboot (to apply workaround). I can live with this.
Hello. Sunday night saw the end to my MacBook pro 17" late 2011.
I got this screen and when it got to 2/3 ish way of loading the screen would look normal grey instead of the lines but then just go black and start again. I have attached a photo. I did a google and found that it seems my graphics has died. Why couldn't it happen when they were fixing them
I popped to the apple store and they said it needed a logic board and they don't make them anymore. I also asked about trading it in and apparently it has no trade in value.
I have come across this thread and tried this morning to do it the "simple Way" :
This stopped the lines on the screen but now I just have the apple logo and the bar that does fill now. I feel this is slight progress but not sure where to go now. Is there a way to see where it is failing? I tried booting the bootcamp and had a very strange screen thing going on. some weird colours came on.
I fear that this may have already been discussed but there are now 100 pages to read and thought someone could quickly guide me to a solution.
All hep much appreciated.

OOOPs! I spoke too fast... was trying to close an opening program and once more the curor disappeared. I don't have a mouse and maybe I have to have the pad reset or something like that. Got it working again last night and this morning things worked fine...then I think I made a mistake in leaving the computer running to go to lunch. When I got back once again the cursor was gone...and when I rebooted...shock! it was back to the original problem. So I had to redo the fix you suggested and it opened but within 3 minute of each time the cursor disappeared.... all day long... very frustration....
now it is working again after I googled youtube for some help and found this video for trackpad issues... EVERYONE SHOULD SAVE IT AND USE IT... he got the info from an Apple repair person ... never heard of this before...
1. Attach the MagSafe power cord
2. Power off the MacBook Pro
3. Press the Left-Shift / Control/Option and Power button at the same time and hold for 5 seconds.
4. Release them all at the same time
5. Then power on the MacBook
if it's not fixed then we assume it's hardware problem but for the time being you can get rid of it while pressing trackpad with little force on top corners.
I had to do this two times before it seemed to start working again. I am keeping my fingers crossed and will power down the computer tonite and hope it works again tomorrow and no more problems.
Very frustrating and stressful for this 70 year old man.

If you did the instructions which have 2 in front of them...you made a big mistake.
Just do the number 1 and then enter the three lines of code. ...make sure you get those lines exactly right...I made mistakes two times with putting an underscore instead of just space...and used a dash instead of = sign.

I am fairly certain I did it character for character. Is there a way to check it I have done it wrong? I put the 3 lines in, presses enter then it rebooted and the code screen can back on scrolled through a load of text and then rebooted and that’s where I am now.
Did you actually let the bar do its thing? If so your desktop should become visible. Did you ignore the #2s and just type each line and return each time? My computer also now has the black screen with all the display of what is going on before the Apple with bar appears which should fill in and finally after a rather long pause... open your desktop to what it was before. I hope someone else can answer. I suggest that you do it one or two more times...it took me more than once to get it right....maybe even wait until the computer cools down? Just guessing.
I have just got back home and tried to turn it back on. It fired up with a load of code now I have the Apple logo. I shall leave it on and see what happens.
It had the bar for a minute or so and has just rebooted. Gone back into code it does say operation failed sometimes. Think you may be able to see in the photo.
Back to Apple logo and it has stayed on that longer.
How long should I leave it before it’s clearly not working?

I have just come back from football and it appears to have not moved from when I left 3 hours ago.
I don't know what to say... maybe AppleMacFinder who started this with the advice has further information. If you did the 3 lines one by one with enter after each one and there was no error, you probably did it okay. I see the photo with the lines and apple logo and bar in the finder. The bar should activate and show where the reboot is and finally the page should disappear the the photo on your desk top appear.
If it is not booting you might have to do the Linux route which some seem to say works very good. Sounds complicated to me but I guess it has to do with the numbers 2 instructions...you have to burn to disk and then insert in your drive and run it...but not sure how that works.
Good luck!
I am still having issues with my own computer....did not boot up properly this morning after working last night.
It was working fine last night...this morning I just booted up and it reverted back to the bad old issues with lines etc and blank screen and rebooting. So I re-did the #1 instructions again and it booted. But the cursor had the same problem and so I redid the trackpad fix I shared above and at the moment it is working okay again. I have also removed Safari and iTunes from automatic Open at Start up so things are simpler when I boot. I can always open them from the dock.
I wonder if AppleMacFinder or someone knows why after shutting down and 8 hours of non use that my system is reverting back to the bad old problem? Help? I don't mind doing the #1 fix every time but it is irritating that it is not remaining the same like you mentioned it would. Didn't you say you could not go backwards? I guess every computer has its own issues which are individual and cannot be anticipated. Still this is better than nothing at all. Way better!!!
The bar goes through the process to the end and My regular desktop with everything on it is coming up....more slowly than usual... but my BIG problem right now is that my cursor disappears after about 3 minutes and freezes all the programs so that nothing is working at all and I have to force it to shut down.
Also I think that once you get it working you have to always shut down using the power key and NOT shut down with the commands in the tool bar. For some reason it then reverts back to the old problem with stripes across the screen and not booting up at all...going to white screen and then restarting over and over again.
I hope that the owner of this post will try to respond to you because he knows much more about these things than I do.
There was an update. You'll need to reapply whatever method worked for you last time.
what do you mean by an update? An update on what? After it worked for a while, I shut down my computer using the Shut Down Command in the Apple to the left on the tool bar. That seems to revert my computer back to the bad thing it was before I used the 3 line commands after pressing Command S. I redid that and it boots up again. I have since decided to shut down my computer manually each time pressing the power button and since then, it boots up fine. My problem is with the cursor disappearing after about 3 minutes. At first a couple of times it worked for some hours continuously after doing the LeftShift/Control/Option/PowerButton thing for 5 seconds mentions in my post above... but now it does not respond to that anymore. It is possible the track pad needs to be reseated and I will try to get someone to do it when I get to Bali in July. I am very happy at least to get it booting up and am forever thankful that AppleMacFinder figured that out.
$59 Isn't bad at all!
Better then a motherboard in a parts bin.
And as it pays for the design alone of the unit, and a happy customer. Support too maybe.
And no headaches to keep trying to jury rig one yourself.
And it is more permanent solution.
Aesthetics wise. Looks nice too.
I would buy a few to try.
In this world, you buy to fix and make it cheap.
It comes back to haunt you.
Especially when you have fixed 1000's of these.
And went through all hell making them better.
