Step #2 in Installation says, "AppleIntelInfo.kext: Download and install" (my emphasis). However, installation "Load" (using the kextload command in terminal) of kext doesn't happen until steps 4 "Baseline" and 9 "Verify." Despite reading through these instructions multiple times, I took literally the instruction to "install" that kext using KextBeast putting it in L/E in step 2.

Bad things then happened requiring a restore from my SuperDuper clone. I found other posts from people doing the same thing and I even saw reports of problems resulting from AppleIntelInfo.kext just sitting on the desktop. So it appears I'm not the only person to ever make this error.

To help others, I might recommend editing step 2 to say something like, "AppleIntelInfo.kext: Download, do not install yet, save in a location other than Desktop, load it using "kextload" command in terminal in steps 4 & 9." Perhaps my edit is too obvious, but hopefully others reading this post will avoid a similar hiccup.

Hi, I have a Z97 setup with 4790K + 1060 GTX + headless iGPU using SMBIOS 15,1.

Does this guide apply for me? (I have tried but iGPU always has fixed frequency of 1,25 ghz and only one pstate)

I will start over If you say yes and provide all the needed files for problem reporting.

Thank you

Is there anything I can do for iGPU, or should I leave it as is. (1,25Ghz all the time)
1.25 GHz is native for AirPlay Mirroring (Intel Quick Synch) support, nothing to do

What about C6 state? Should we disable it with PluginType=Yes?

I have a i5 8600k and a Asus z370-f motherboard...in the supported CPU list it says "Coffee Lake/UHD630+ (Core i3/5/i7 8xxx, 8th Generation; 300 Series, except Z370, motherboards)". Does that mean that Power Management doesn't work for me, no matter what I try? Also in the table with the Settings it says that coffee lake works with "300_Series (-Z370)" :(
