Note: the El Capitan installer must be in the Mac's root application folder for this to work as the terminal command goes there to get it. Also the Flash drive must be formatted with a GUID partition to boot the OS (El Capitan on Flash boot drive). Create Bootable USB Installer for Mac on Windows 10. The first step you should take is formatting your hard drive before you install El Capitan on Mac. And create OS X 10.11 El Capitan bootable USB Installer on PC or create bootable USB for Mac on Windows, before skipping this step.

These advanced steps are primarily for system administrators and others who are familiar with the command line. You don't need a bootable installer to upgrade macOS or reinstall macOS, but it can be useful when you want to install on multiple computers without downloading the installer each time.

What you need to create a bootable installer

A USB flash drive or other secondary volume formatted as Mac OS Extended, with at least 14GB of available storage
A downloaded installer for macOS Big Sur, Catalina, Mojave, High Sierra, or El Capitan

Download macOS

Download: macOS Big Sur, macOS Catalina, macOS Mojave, or macOS High Sierra
These download to your Applications folder as an app named Install macOS [version name]. If the installer opens after downloading, quit it without continuing installation. To get the correct installer, download from a Mac that is using macOS Sierra 10.12.5 or later, or El Capitan 10.11.6. Enterprise administrators, please download from Apple, not a locally hosted software-update server.
Download: OS X El Capitan
This downloads as a disk image named InstallMacOSX.dmg. On a Mac that is compatible with El Capitan, open the disk image and run the installer within, named InstallMacOSX.pkg. It installs an app named Install OS X El Capitan into your Applications folder. You will create the bootable installer from this app, not from the disk image or .pkg installer.

STEP 1: Download macOS Mojave The full operating system is a free download for anyone who has purchased Mac OS X Snow Leopard, Lion, or Mountain Lion or has a Mac preloaded with OS X Mavericks, Yosemite, El Capitan, macOS Sierra, or macOS High Sierra. Download the Application from the Mac App Store using your Apple ID on any of these specific.
To build a VM running macOS, follow the directions below: Download the installer from Mac App Store (it should be available in the 'Purchases' section if you've acquired it previously). The installer will be placed in your Applications folder. (Should work for Yosemite, El Capitan, Sierra and High Sierra, Mojave - 10.10-10.14.).

Use the 'createinstallmedia' command in Terminal

Connect the USB flash drive or other volume that you're using for the bootable installer.
Open Terminal, which is in the Utilities folder of your Applications folder.
Type or paste one of the following commands in Terminal. These assume that the installer is in your Applications folder, and MyVolume is the name of the USB flash drive or other volume you're using. If it has a different name, replace MyVolume in these commands with the name of your volume.

Big Sur:*

Catalina:*

Mojave:*

High Sierra:*

El Capitan:

* If your Mac is using macOS Sierra or earlier, include the --applicationpath argument and installer path, similar to the way this is done in the command for El Capitan.

After typing the command:

Press Return to enter the command.
When prompted, type your administrator password and press Return again. Terminal doesn't show any characters as you type your password.
When prompted, type Y to confirm that you want to erase the volume, then press Return. Terminal shows the progress as the volume is erased.
After the volume is erased, you may see an alert that Terminal would like to access files on a removable volume. Click OK to allow the copy to proceed.
When Terminal says that it's done, the volume will have the same name as the installer you downloaded, such as Install macOS Big Sur. You can now quit Terminal and eject the volume.

Use the bootable installer

Determine whether you're using a Mac with Apple silicon, then follow the appropriate steps:

Apple silicon

Plug the bootable installer into a Mac that is connected to the internet and compatible with the version of macOS you're installing.
Turn on your Mac and continue to hold the power button until you see the startup options window, which shows your bootable volumes and a gear icon labled Options.
Select the volume containing the bootable installer, then click Continue.
When the macOS installer opens, follow the onscreen instructions.

For more information about the createinstallmedia command and the arguments that you can use with it, make sure that the macOS installer is in your Applications folder, then enter the appropriate path in Terminal:

Big Sur: /Applications/Install macOS Big Sur.app/Contents/Resources/createinstallmedia

A bootable installer doesn't download macOS from the internet, but it does require an internet connection to get firmware and other information specific to the Mac model.

Os X El Capitan Usb Installer Windows

Supported version: 0.6.7

While you don't need a fresh install of macOS to use OpenCore, some users prefer having a fresh slate with their boot manager upgrades.

To start you'll need the following:

4GB USB Stick
For USB larger than 16 GB to format in FAT32 use Rufus method
- This will require Python installed(opens new window)

# Downloading macOS

To grab legacy installers is super easy, first grab a copy of OpenCorePkg(opens new window) and head to /Utilities/macrecovery/. Next copy the folder path for the macrecovery folder:

From here, you'll want to open up a Command Prompt and cd into the macrecovery folder that we copied earlier:

Now run one of the following depending on what version of macOS you want(Note these scripts rely on Python(opens new window) support, please install if you haven't already):

macOS 11, Big Sur Note: As this OS is quite new, there's still some issues with certain systems to resolve. For more information, see here: OpenCore and macOS 11: Big Sur
- For first time users, we recommend macOS 10.15, Catalina
Nvidia GPU Note: Reminder to verify whether your hardware support newer OSes, see Hardware Limitations

This will take some time, however once you're finished you should get either BaseSystem or RecoveryImage files:

BaseSystem	RecoveryImage

Now with our installer downloaded, we'll next want to format out USB.

# Making the installer

Here we'll be formatting our USB and adding macOS onto it, we have 2 options:

Os X El Capitan Bootable Usb Installer

Disk Management method
- GUI Based, simplest way
- Only UEFI systems are supported(ex. 2012+)
Rufus method
- GUI Based, simplest way
- For larger USB drives(16GB+)
diskpart method
- Command line based, little more work
- Required for legacy systems(ie. non-UEFI, pre-2012)

# Disk Management method

Simply open up Disk Management, and format your USB as FAT32:

Right click the Start Button on your task bar and select Disk Management.
You should see all of your partitions and disks. On the bottom half, you'll see your devices. Find your USB.
You'll want to format the USB to have a FAT32 partition.

If you have multiple partitions on the USB, right click each partition and click Delete Volume for your USB (This will remove data, make sure you have backups and only remove partitions from your USB)
- Right click the unallocated space and create a new simple volume. Make sure it is FAT32 and at least a gigabyte or two big. Name it 'EFI'.
Otherwise, right click the partition on the USB and click Format and set it to FAT32.

Next, go to the root of this USB drive and create a folder called com.apple.recovery.boot. Then move the downloaded BaseSystem or RecoveryImage files. Please ensure you copy over both the .dmg and .chunklist files to this folder:

Now grab OpenCorePkg you downloaded earlier and open it:

Here we see both IA32(32 Bit CPUs) and X64(64 Bit CPUs) folders, choose the one that's most appropriate to your hardware and open it. Next grab the EFI folder inside and place this on the root of the USB drive along side com.apple.recovery.boot. Once done it should look like this:

# Rufus method

Download Rufus(opens new window)
Set the BOOT selection as not bootable
Set File System as Large FAT32
Click Start
Delete all file autorun in USB Drive partition

Now grab OpenCorePkg you downloaded earlier and open it:

# diskpart method

diskpart method

Press Windows + R and enter diskpart.

Now run the following:

Now grab OpenCorePkg you downloaded earlier and open it:

Legacy Install Setup

If your firmware does not support UEFI, see below instructions:
