Not open for further replies.
Yeap, but now it is :) Conclusion - always read the full guide! I've turned CMS on and voilà...

But the Intel HD 5500 works without backlight regulation. Will it be hard to repair that? I see that you have BDW with HD5500 too.

Hello I need help.
1. What is full meaning of CMS that you enabled that graphics start working flawlessly?
2. I used Rehab, config.plist do my graphics Intel hd 5500 and followed the process in enabling QE have gotten to the stage of adding correct figures in the ig-platform I get kernel panic and can't boot with it after I added it; tried many times can't boot to desktop with the correct ig code. Here is a screenshot of k panic it displays, I dont know what am doing wrong
Help

"CMS" probably actually meant "CSM" (compatibility support module).
For your panic, read guide, specifically the section regarding DVMT:

You have to change your DVMT pre-alloc to 64MB or more. If you can't change it, boot with invalid ig-platform-id, apply this patch on config.plist/KernelAndKextPatches/KextsToPatch:
Name: AppleIntelBDWGraphicsFramebuffer
Find: 06002616 01030303 00002002 00005001
Replace: 06002616 01030303 00003001 00009000
Then boot with 0x16260006. This patch works only with this ig-platform-id.
 
WOW OMG!
Worked flawlessly after doing your instructions.
Thanks very much Fivos.
Wow, am so happy.:headbang::clap:
