I'm using iMac15,1 profile.
Without iGPU, Photos app is crashing. I have even created a new library but no luck. Right now I'm back to my default settings. I have iGPU enabled in BIOS, nothing is selected in Graphics section of config file, and I'm using WhateverGreen. Everything seems to work...
This method did not work for me. I already had iGPU enabled so I renamed iGPU to GFX2 and PEGP to GFX0. I removed WhateverGreen kext and also enabled "Inject Intel" and selected the Haswell platform-id.
So I had to enable iGPU in order to stop crashes from occurring when using Photos app and viewing videos (most recently, system froze when viewing a video sent on WhatsApp on the computer). Previously, when I was enabling iGPU, Netflix would not work but for some reason, it's working this time...
It works now. I moved all kexts back to Other folder. So either your framework file or the GVA kext you had in your Other folder or both together did the trick.
One issue that popped up again is the Photos app crash. As soon as I start using it, the system locks up.
