If you use pkgutil to expand the InstallMacOSX.pkg it opens to three items, the Distribution file, InstallMacOSX.pkg and Resources. You can alter the Distribution file to ignore the supported platform check, see below.

Creating the Install OS X El Capitan.app on a mac that came with a newer OS than El Capitan.

Η Apple σας επιτρέπει να κάνετε αναβάθμιση στο νέο OS X El Capitan απευθείας από το εγκατεστημένο OS X Yosemite, αλλά τουλάχιστον μία φορά κάθε δύο χρόνια συνιστάται να κάνετε μια “καθαρή. Download OS X El Capitan. Download DiskMaker X. Double-click on the.dmg file to open it and drag-and-drop the DiskMaker X app into the Applications folder. Now load DIskMaker X. When you load the app, it will ask you which version of OS X do you want to make a boot disk of. You can choose Mavericks, Yosemite and of course, El Capitan.

Download the InstallMacOSX.dmg from Section 4 of How To Upgrade To El Capitan

Double-click to open InstallMacOSX.dmg to Install MacOSX.pkg.

Drag InstallMacOSX.pkg to the Desktop.

Open Terminal, enter the text

A folder will be created on the Desktop after a while with the contents of the .pkg file.

In there you will see an item called Distribution, Control-click on that and select Open With

Os X El Capitan Bootable Usb From Windows

go to Other and select Text Edit.

When the file opens scroll down to the section that reads,

Create Bootable Os X El Capitan Usb Drive

function isSupportedPlatform(){

type in at the end return true; so it now reads as,

function isSupportedPlatform(){return true;

Now click Save and close the document.

Go back to Terminal and enter the text,

press Return, after several minutes, be patient, (check to see if the prompt has returned to Terminal) a new package will be created on the Desktop.

When created double-click on that and an installation window will open where you will now convert the

new InstallElCapitan.pkg to the Install OS X El Capitan.app which will be placed in your Applications folder.

You can now create a bootable USB using the install app and createinstallmedia,

If you have the time I would be grateful if you could give this a trial, it works here on my mac, but I would like confirmation from yourself or any others reading this that the procedure works on macs that came with macOS Sierra or newer pre-installed. Oh and tell me if my description of the procedure is easy to follow and understand..

Bootable Mac Os X El Capitan

This is Ultimate tutorial for installing Mac OSX up to EL Capitan 10.11.
You don't need working mac installation or AHCI capable motherboard, it can be done on any PC.
Tools that you need:
OSF Mount - http://www.osforensics.com/tools/mount-disk-images.html - This is most important tool, it can mount efi partition on image and edit it.
image link: https://goo.gl/nMcpOG
win 32 disk imager - http://win32-disk-imager.en.uptodown.com/ - this will be used to write image to USB, you can also use other software, there are many of them, i use this one.
In case you did not listen to me and you want to do this harder way:
http://www.hackintosh.zone/file/828-bootdiskutility-v212015/ - utility that can install clover from windows.
https://sourceforge.net/projects/cloverefiboot/files/Installer/ - Clover installer package
The most important note!!! ---- You need Sata kext in 10.11 folder, that will make your HDD to show up in disk manager, without it you will get still waiting for root device and your HDD wont show up in disk utility and you wont be able to install EL Capitan on your HDD.
