Of course the Repair Extension Program criteria weren't met because the computer did not display the specific symptoms to meet the program's criteria for a free repair. So I paid a total cost of $345.48 to get the motherboard replaced for a repair which to me appeared to be video-related.

I have a MacBook Pro Early 2011 and the GPU has died. I want to switch to IntegratedGraphics only until I get my Logic Board replaced.

I've tried:

• gfxcardstatus and I get this:

• There is no External Display connected btw and I've never used one.
• I moved /System/Library/Extensions/AMD* -> ~/DisabledExtensions/
• I've tried Single User Mode and did the same thing as above.

I really don't know what else to do. I want to know if there is a wayto login to EFI/BIOS and disable it or anyway whatever it takes to just kill thatannoying AMD that is making my screen blue and twitchy.

Finally!! ( in 2015...? )MacBook Pro Repair Extension Program for Video Issues

I hope this helps everyone.

you definitely should try this one:

(that is still on archive.org: Macbook Pro Discreate Graphics Card Issue Fix Updated)

I’m writing this reply from my until-now broken MacBook Pro 2011 dammed GPU piece of technology.

You'll get away working without the AMD GPU, which vs. having a dead USD$2k… paperweight isn't really a bad deal.

Additional Solution:

I found that doing the above will let you login, but Mac OS would still try to use the discrete graphics card without the driver. The result is that even though you can login, the graphics will be so slow that the machine is mostly unusable.

The second answer (the one that uses ArchLinux ISO to change the EFI variable) on this link solved my problem:

My Mac OS now boots up default to integrated graphics mode.

LangLangC

You did right so far. But you have to move all ATI files from that folder as well. It will work after that, but the graphic will be slow.

Make sure to boot in verbose mode (Cmd-S at startup).

Note that the Folder DisabledExtensions needs to exist already.

Addendum: It’s important to put that Intel3000.....kext file back! You will need that one!

Thank you all I have used the linked procedure - http://www.asyncro.com/2014/03/24/macbook-pro-discreate-graphics-card-issue-fix-updated/Although while rebuilding the drivers cache it has given me down the line 'segmentation fault' but when it booted:

I have noticed in Energy Saver 'Automatic switching check box was removed now'.Also My external video 6770m card is completely disabled as to test I have tried the game which previously was always going to 2nd gpu but now only using integrated GPU.

Also before doing all this I have updated to Yosemite.

Benefit of upgrade was : Now when the system panics- Apple has made some changes in 6770m gpu drivers that is forcing the CPU to reinitialize or reboot the GPU - so now when system reboots it comes back safely. So no more recovery mode boot or single user or pram resets or SMC. It was coming back everytime.

But the disadvantage was everytime it was switching gpu during normal use it was crashing the laptop and rebooting. I had previously noticed the Webex Application infact was switching to external gpu and thus causing the system to hung[Maverik] or now reboot in Yosemite.

But now atleast its not anymore doing this, once I have disabled the 2nd GPU. So atleast, now I can use its internal card completely and its not a $3500/- paperweight.

Also we do not need gfxcardstatus app once we disable the external card.

Best of luck guys.

Program For Video Editing

I got into single user mode without much trickery, as my AMD card seems to work up to the point where the drivers are loaded, just with stripes across the screen. So I got to remove the drivers as described at asyncro. I rebuilt the kextcache (alternatively deleted it), but my Mac doesn't boot to internal graphics but uses the discrete graphics (according to gfxcardstatus), just totally slow and with what looks like 32 colors and pinstripes across the screen. As soon as I restore the drivers, it freezes at boot with a grey screen. Not sure what I am missing.

gfxcardstatus 2.3 complains it can't switch to internal graphics because there is an external display connected (not true), 2.2.1 just doesn't work.

I am on Yosemite 10.10.1

I also have FileVault enabled, so I am seeing the broken discrete graphics right from the start when I am prompted for my password, long before any driver from hard dis can be loaded.

Apple has determined that graphics cards in some late 2013 Mac Pros, manufactured between February 8, 2015 and April 11, 2015, may cause distorted video, no video, system instability, freezing, restarts, shut downs, or may prevent system start up.

Mac Pro Repair Extension Program For Video Issues On My Computer

Apple or an Apple Authorized Service Provider will repair eligible Mac Pro models affected by the video issues free of charge until May 30, 2018. Apple lists a turnaround time of about 3-5 days.
Apple says both graphics cards must be replaced on Mac Pros exhibiting any of the problems listed above. AMD's FirePro D500 (high-end model) and D700 (built-to-order) GPUs are affected. AMD's FirePro D300 GPU on the base Mac Pro is not listed.
Customers can book an appointment with the Genius Bar at an Apple Store or visit an Apple Authorized Service Provider to determine if their Mac Pro is eligible for coverage. Unlike Apple's voluntary recall of some international AC wall adapters last week, Apple is unlikely to publicly announce this repair program on its support website, but it may contact some customers directly.
