This is a brief guide on how to create a vanilla El Capitan (also same process for Sierra) OS X Installer USB with an updated prelinked kernel containing FakeSMC.
It is tailored for those users who want to understand the “nuts and bolts” of how to create an installer and also to help brush up on their terminal skills (rather than have one made for them with the numerous automated “tools” available or even Apple’s createinstallmedia) :
Specifically, it is also a “Proof of Concept” which shows that installation is possible without even having to rely on boot loader kext injection.
Existing Yosemite installation (or Mavericks - see post#4 for steps 7,8)
“Install OS X El Capitan.app" downloaded to the Applications folder
FakeSMC.kext - Slice or Kozlek branch
Bootloader - Clover or Chameleon
8GB or larger USB drive (16GB recommended), formatted HFS+ (MBR or GUID) named “Installer”
1. Boot into Yosemite with the kext-dev-mode=1 boot flag
2. Open OS X terminal and type the following lines, followed by <Enter> after each line.
The image restore and file copying may take a while to complete, and at the end of the process, the Installer volume is renamed to “OS X Base System"....
hdiutil attach /Applications/Install\ OS\ X\ El\ Capitan.app/Contents/SharedSupport/InstallESD.dmg
asr restore -source /Volumes/OS\ X\ Install\ ESD/BaseSystem.dmg -target /Volumes/Installer -erase -format HFS+ -noprompt -noverify
rm /Volumes/OS\ X\ Base\ System/System/Installation/Packages
cp -av /Volumes/OS\ X\ Install\ ESD/Packages /Volumes/OS\ X\ Base\ System/System/Installation
cp -av /Volumes/OS\ X\ Install\ ESD/BaseSystem.dmg /Volumes/OS\ X\ Install\ ESD/BaseSystem.chunklist /Volumes/OS\ X\ Base\ System
diskutil unmount /Volumes/OS\ X\ Install\ ESD
3. Right click on the “OS X Base System” Volume and click “Get Info”
4. Click on the lock icon and untick “Ignore ownership on this volume”
5. Extract/Copy the El Capitan Kernels folder into /System/Library/ of the USB with Pacifist. NB It is found in the "Essentials.pkg" in /System/Installation/Packages
6. Delete or Rename the original /System/Library/PrelinkedKernels/prelinkedkernel —> OG.prelinkedkernel
7. Copy FakeSMC.kext and other necessary kexts (e.g. VoodooPS2Controller.kext for laptops) into the /Library/Extensions folder of the installer USB using Finder.
8. Back in terminal, type the following lines, followed by <Enter> after each line to rebuild the prelinkedkernel…..
chmod -R 755 /Volumes/OS\ X\ Base\ System/Library/Extensions
chown -R 0:0 /Volumes/OS\ X\ Base\ System/Library/Extensions
touch /Volumes/OS\ X\ Base\ System/System/Library/Extensions
kextcache -u /Volumes/OS\ X\ Base\ System
Any errors should be noted but the output below is normal e.g.
9. Install your Bootloader targeting the OS X Base System volume
10. Boot your system with the USB without injected kexts into the OS X Installer GUI....
The original prelinked kernel in a fresh install of El Capitan will also lack FakeSMC ie it will only be linked to Apple signed kexts. In order to boot into El Capitan the first time around without boot loader kext injection, the PLK needs to be rebuilt for the El Capitan volume like we did for the installer:
1. Boot into Yosemite with the kext-dev-mode=1 boot flag
2. Delete or Rename the original /System/Library/PrelinkedKernels/prelinkedkernel for the El Capitan volume —> OG.prelinkedkernel
3. Copy FakeSMC.kext and other necessary kexts (e.g. VoodooPS2Controller.kext for laptops) into the /Library/Extensions folder of El Capitan using Finder
4. Back in terminal, type the following lines, followed by <Enter> after each line to rebuild the prelinkedkernel. In this example, the El Capitan volume is named "El_Capitan" - change if you have named it something else...
chmod -R 755 /Volumes/El_Capitan/Library/Extensions
chown -R 0:0 /Volumes/El_Capitan/Library/Extensions
kextcache -u /Volumes/El_Capitan
5. Install your Bootloader targeting the El Capitan volume. This step is only necessary if you are installing El Capitan on a new drive without existing boot loader (not required if installing on a disk with existing boot loader beside Yosemite).
6. Reboot your system without injected kexts into El Capitan!

Updates for Sierra and High Sierra
Custom Prelinkedkernel Generator Tool
I have made a custom prelinkedkernel generator "PLK.tool" for Sierra + El Capitan. Instructions:
1. Download and extract the attached BaseSystem_PLK.tool.zip into your ~/Downloads folder.
2. Copy any extra kexts necessary for booting your hack to ~/Downloads/BaseSystem/ExtraKexts (e.g. FakeSMC, VoodooPS2Controller), making sure SIP is disabled.
3. Copy BaseSystem.dmg to ~/Downloads/BaseSystem
4. Open terminal and run the following commands...
chmod +x PLK.tool
---> supply your admin password ---> will place your new custom prelinkedkernel on the desktop.

Let's say: I'm trying to create a Bootable Hackintosh USB for Mac OS High Sierra [Latest Stable Version], and I'm using a Virtual Machine [with Mac OS High Sierra] on my Windows 10.
What BIOS Settings should I change for - LENOVO Motherboard BIOS?
What should I keep in mind when using a Virtual Machine [MacOS] for the Bootable USB Creation Process?
Should I use Clover EFI Bootloader or Clover Configurator, or Both? What settings should I change change in those?
Does it matter which version(s) of Clover Sofwares I use? Will they support USB Creation for ALL versions of MAC Operating Systems? [Or do they only support some versions of Mac OS?]
Thanks in Advance for your help!
I have VoodooPS2 kext installed. Tried to google the solution but only found changing MouseMultipliers which won't help - I changed all of them, tried to set around 3x times bigger values, rebuild kext cache, replaced the ones in EFI, rebooted but nothing changed, TrackPoint is still slow. Is there any other way to do it? I'm also attaching my problem_reporting files.
Clover r4644 ISO compiled with GCC and minimal config.plist compatible for use in VMWare Workstation.
Tested with unlocked Workstation 14 running OSX 10.9 -->10.14 guest in Windows X64 host.
1. Download and unzip "EFI_Clover_r4644 for VMware.zip". Mount Clover-v2.4k-4644-X64 by double clicking on it.
2. Mount your VM's EFI System Partition eg in terminal
sudo diskutil mount disk0s1
3. Copy EFI folder from step 1 into the EFI partition
4. Shutdown the VM, add bios.bootDelay = "3000" to your VM's vmx file
5. Reboot your VM, press <F2> to access the VMware Boot Manager and add CLOVERX64.efi to the boot menu.
Substitute your own unique and valid MLB and ROM variables in the /EFI/CLOVER/config.plist (Rt Variables section) to activate iMessage/Facetime on your VM.
