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.
