It's not a system we already have in support here, so you'll be the guinea pig.


You may follow a classic Clover installation process or a classic manual process with Enoch bootloader. You'd have to start with a minimal bootpack using just the basics such as FakeSMC + PS2 controller kexts.


Once you identify the rest of your hardware (LAN, audio, etc.), you may add any necessary kexts as required.



Typical manual installation, with Enoch bootloader, from an existing Mac or Hack, would include the following:

1) 10.11 USB installer creation

  • Double click on InstallESD.dmg found in Install OS X 10.11 El Capitan.app/Contents/SharedSupport to mount the dmg image
  • Then, using Terminal app, mount BaseSystem.dmg (hidden file)
open /Volumes/OS\ X\ Install\ ESD/BaseSystem.dmg
  • Use Disk Utility to restore the contents of BaseSystem.dmg on a USB key (or HDD partition) formatted Mac OS extended (journaled).
  • Remove link for Packages in folder System/Installation of your USB key
rm /Volumes/OS\ X\ Base\ System\ 1/System/Installation/Packages
  • Copy folder Packages located in InstallESD.dmg to folder System/Installation of your USB key
cp -R /Volumes/OS\ X\ Install\ ESD/Packages /Volumes/OS\ X\ Base\ System\ 1/System/Installation
  • Copy the 2 hidden files (BaseSystem.dmg & Basesystem.chunklist) of InstallESD.dmg to the root of your USB key
cp /Volumes/OS\ X\ Install\ ESD/BaseSystem.* /Volumes/OS\ X\ Base\ System\ 1
  • USB installer should now have all the required OS X files and packages installed


2) USB installer finalisation: Enoch bootloader + bootpack installation

  • Run Enoch r2795 (latest at time of writing) and install on the USB installer Enoch-rev.2795.zip
  • Copy the Enoch r2795 installer package to the root of the USB installer
  • Unzip the attached minimal bootpack and copy the resulting Extra folder to the root of the USB installer Essential_bootpack.zip
  • Copy all kexts from folder Extra/Extensions of the pack to folder /Library/Extensions of your USB installer, then repair permissions
  • sudo chmod -Rf 755 /Volumes/OS\ X\ Base\ System\ 1/Library/Extensions
    sudo chown -Rf 0:0 /Volumes/OS\ X\ Base\ System\ 1/Library/Extensions
  • Create a folder called Kernels under /System/Library (normally, it won't exist at that stage)
  • Copy the El Capitan kernel to /System/Library/Kernels. Copies of the kernels are available here.


3) 10.11 installation on target system

  • Boot the 10.11 USB installer (it may take a little time to kick in)
  • If/when prompted for USB keyboard and/or mouse at installer startup, just press [ENTER] or [sPACE] twice
  • At OS X installer main screen, open up Disk Utility in Utilities menu
  • If applicable, partition your target disk in GPT/GUID scheme
  • Create your target 10.11 partition and format it as OS X Extended
  • Close Disk Utility and proceed with OS X 10.11 installation as usual


4) Post-installation fine-tuning

  • Reboot the 10.11 USB installer (it may take a little time to kick in)
  • If/when prompted for USB keyboard and/or mouse at installer startup, just press [ENTER] or [sPACE] twice
  • At OS X installer main screen, open up Terminal in Utilities menu
  • Identify your freshly made 10.11 partition
  • Copy the Extra folder from the USB installer to the target 10.11 disk partition
cp -R /Extra /Volumes/<your 10.11 partition name>/
  • Reboot the 10.11 USB installer, press a key at delay bar (or F8) to interrupt boor process and select your freshly made 10.11 disk partition to boot El Capitan for the 1st time
  • Complete the 1st boot installation finalisation
  • Once at the 10.11 desktop, run the Enoch r2795 package from your USB installer to install Enoch on your disk drive; it should be installed on the 1st partition
  • Eject the 10.11 USB installer and put it aside
  • Copy all  kexts from /Extra/Extensions to /Library/Extensions, where all kexts should go from now on. Ignore and acknowledge the error pop-up messages related to kext incorrect permissions/installation
  • Rename /Extra/Extensions to /Extra/Old_Extensions
  • Open up Terminal to repair permissions and rebuild cache
sudo chmod -Rf 755 /L*/E*
sudo chown -Rf 0:0 /L*/E*
sudo chmod -Rf 755 /S*/L*/E*
sudo chown -Rf 0:0 /S*/L*/E*
sudo touch -f /L*/E*
sudo touch -f /S*/L*/E*
sudo kextcache -Boot -U /
  •   Reboot your finalised El Capitan installation


NB: this is a kind of generic installation process and does not obliterate any requirement you may have to use a patched DSDT or add bootflags or options I have not mentioned.
