pafkata is using Hervé's patched kexts from Chameleon guide where hotpatches can't be utilized like Clover, so the bin patches are done on the AppleHDA and AppleHDA_IDT92HD90.kext has the actual codec info.

Sierra Guide See here for install guide, just replace with Sierra bootpack. E7x70_Sierra.zip - See Update files below Known Issue & Workaround: HDMI-Output works but if connect HDMI-Cable the local Display goes off and never recovers. I had tried different configurations but none panned out. Here's a workaround: Close the LID until you see the HDMI display becomes the primary display, then open the LID. It'll switch LCD as primary and HDMI as secondary. NOTE: Workaround is only needed on clean boot, no issue if system has gone through a sleep/wake cycle Update: Fixed it by modifying EDID with this kext, but not work for Mojave. Post Install: Enable Brightness Control and Trackstick Scrolling Trackstick Scrolling Download and install Smartscroll for trackstick scrolling Touchpad - 2 fingers scrolling, 2 finger tab for right click, tap and drag Brightness Control Download and Install Karabiner-Elements Launch Karabiner-Elements Copy karabiner.json to ~/.config/Karabiner karabiner.json.zip or copy the settings according to diagram below Now use F11 & F12 for Brightness, use F1, F2, & F3 for Volumes Control
