For MacBook Pro users who want to manually control their GPU use, you can use a third party tool like GFXCardStatus which has been around for quite some time and still works on most modern MacBook Pro models as well.You can always return to the Energy preference panel to re-enable the GPU switching feature if desired.This may decrease battery life.” – if you are not OK with that do not disable this option For example, to be able to boot my MBP 8.2, I must remove the ATI and AMD extensions, but in this case, the selected GPU is the Radeon GPU and gfxCardStatus is not able to force the usage of the integrated GPU because it detects an external display even I have no plugged external display.

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.
#GFXCARDSTATUS INTEGRATED ONLY NOT WORKING INSTALL#
To turn off the dual graphics capability of the GPU, install gfxCardStatus for Mac 3, and when I open GFX it freezes in Activity Monitor and never opens.Is gfxCardStatus stil a viable option to force integrated. I’ve saved about twenty 2011 15” MBP using this gem, it’s also free -)
