Warning: this method is not universal. There are boards where the radeon is always visible for the OS. I’m looking a new method with a GRUB boot with Radeon disabled as described in https://help.ubuntu.com/community/UEFIBooting#Setting_up_GRUB2_.28U.29EFI . In 2014, i have installed an ubuntu with this trick but i didn’t know i could start OS X with Grub.
Since 2013, i have a buggy Macbook Pro 2011. As too many buyers, i have the GPU welding problem. At first, it was few artefacts and … my gpu died. So i can’t use the first trick with gfxCardStatus anymore.
Desperately, i tried to force the use of the intel gpu and remove many kext:
AMDRadeonAccelerator.kext AMDRadeonVADriver.bundle AMDRadeonX3000GLDriver.bundle AMDRadeonX4000GLDriver.bundle ATI2400Controller.kext ATI2600Controller.kext ATI3800Controller.kext ATI4600Controller.kext ATI4800Controller.kext ATI5000Controller.kext ATI6000Controller.kext ATI7000Controller.kext ATIFramebuffer.kext ATIRadeonX2000.kext ATIRadeonX2000GA.plugin ATIRadeonX2000GLDriver.bundle ATIRadeonX2000VADriver.bundle ATISupport.kext
But, this is not the solution because your mbp has many problems:
No OpenGL Acceleration: No Photoshop, Slow GUI ... No screen settings
Your mac is only NOT USABLE!!! I try it few hours but i can’t work with it. I bought a 2012 mac mini, 16Go ram and one ssd. Apple FUCK YOU!!!
Since this day, i have installed hackintoshs for friends. And at Christmas 2014, i try to install yosemite on my mbp as it was a hackintosh. AND IT WORKS!!! Ant it is blazzing fast! Ready to save your 2011 mbp? Go.
If you can help me to buy a new one, please donate to (Paypal) ellis at redfight.com

You need another Mac and one usb > 8Go ready to format. I can’t share my the usb iso used due to Apple… With this mac, we’ll build a bootable usb key with the tool Unibeast.
The only trick is to boot on your usb key. To realize it, start your macbook pro with the option key pressed. when drives appear, select the uefi boot icon (the yellow one) .
Now this is the standard Yosemite installer. You can upgrade or format your partition. I have tried with success the two options.
After reboot and account creation, your mbp seems a bit slow. It seems there is an ACPI, Sensor or PowerManagement problem. Your mbp acts as if the cpu temperature was > 90 and the kernel_task process takes > 250%…
type the following lines
$ mkdir -p ~/backup $ cd /System/Library/Extensions/IOPlatformPluginFamily.kext/Contents/PlugIns/ACPI_SMC_PlatformPlugin.kext/Contents/Resources $ sudo mv MacBookPro8_2.plist ~/backup/
Congrats, you have a functional macbook pro 2011. Have fun!!! I hope Apple will replace freely the mbp in future.
I will never buy a mbp with a dedicated GPU. Never!!! This is my second macbook died because of gpu. If it helps you, please donate. If you have problems or this tutorial is not complete, send an email to ellis at redfight dot com.
