Work in Progress:

HDMI Audio (no support yet)

HDMI Audio Supported, updated files in the Sierra guide below

Slow to boot/Restart/Shutdown Better when dual booting with Win10/not sure why

 

Prerequisite:

Set DVMT to 96MB (0x3)

Source =  FireWolf™s guide

Steps to change the DVMT value (Done on Windows or WinPE)

 

1) Universal BIOS Backup ToolKit 2.0.exe - to backup the BIOS (DellInc.-1.5.3.rom) 

    At time of writing - BIOS version 1.5.3

2UEFITool.exe to find the module labeled Setup and extract the PE32 image section (setup.bin)

  Update:

  For Dell Only: Search with this GUID then extracting the PE32 body under it would be faster /easier than finding the module per guide

          899407d7-99fe-43d8-9a21-79ec328cac21

3) Universal IFR Extractor.exe to extract setup.bin to a readable text file

4) Use notepad to search for DVMT in the text file,  2 were found at 0x432 and 0x433

    Both with value of 0x1 but only 0x432 needs to be set to 0x3

5) Format a USB drive to fat32 and create a folder name EFI (SD Card works too)

6) Download the EFI Shell and extract the Boot folder into the newly created EFI folder

     i.e.. /EFI/Boot/bootx64.efi

7) Boot system with the USB and select UEFI Boot

😎 At the grub prompt, enter these commands, hit enter after each command, then exit and reboot

    setup_var 0x432 0x3

    

To verify, just enter setup_var 0x432 and hit enter, the value will be listed

Note: Settings will retain after BIOS update but will reset if you select "Restore Settings" in BIOS!!!

/!\ New Development: If you don't want to mod the BIOS as it might be difficult for some models, you could skip this step by adding 2 new kexts to /EFI/Clover/kexts/Other

Lilu.kext & Whatevergreen

 

BIOS Settings:

Set to "Load Default", Apply, then set the following:

TPM = Disabled

Secure Boot = Disabled

UEFI = Enabled

SATA Operation = AHCI

Wake on Lan /WLan = Disabled

Enable Legacy Option ROMs = Disabled

 

 

Installation:

See here install guide, use below bootpack

E7x70.zip

Note: Must be OS X 10.11.4 and newer for Skylake support

 

Post Install:

 

Enable Brightness Control and Trackstick Scrolling

 

Trackstick Scrolling

  1. Download and Install Karabiner
  2. Launch Karabiner/Preferences/Change key/Point Devices/CursorMove to ScrollWheel
  3. Enable MiddleClick+CursorMove to Scrollwheel

 

Brightness Control

  1. Launch Karabiner/Preferences/Misc & Uninstall
  2. Under Custom Setting, click Open private.xml
  3. Replace file with the attached -> zip.gif  private.xml.zip  
  4. Go back to Change Key Tab and select  'Reload XML'
  5. The new custom file will show on the very top call 'Remap Brightness Key' & 'Remap Volumes Key'
  6. Place the check marks there.
  7. Now use F11 & F12 for Brightness, use F1, F2, & F3 for Volumes Control

(Keyboards with same/similar layout will work with custom xml above too)

Note1: Personally use SmartScroll for Trackstick scrolling with Inertia. Don't really use Touchpad, 2 fingers scrolling and tap and drag does work.

Note2: Please use this beta version of ssdPRGen.sh generate SSDT.aml for Skylake system

Note3: If you're installing Sierra, there's a known artifact issue on the upper left corner!

           Update: Fix can be found here

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

  1. Download and install Smartscroll for trackstick scrolling
  2. Touchpad - 2 fingers scrolling, 2 finger tab for right click, tap and drag

Brightness Control

  1. Download and Install Karabiner-Elements
  2. Launch Karabiner-Elements
  3. Copy karabiner.json to ~/.config/Karabiner karabiner.json.zip or copy the settings according to diagram below
  4. Now use F11 & F12 for Brightness, use F1, F2, & F3 for Volumes Control
