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:

MacBook Pro: How to disable discrete GPU permanently from EFI?

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

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).

mount -uw /  (to be able to move System files)
mv /System/Library/Extensions/ATI* /System/Library/DisabledExtensions/

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!
