EI Capitan (10.11) is the last release of OS X. After it, the OS versions are under a name called macOS. From our observation, there are still many people using EI Capitan on their Mac as some of the apps are not running on macOS. Hence, if your Mac was something wrong with it and you need to create a bootable installation media to reinstall OS X EI Capitan on your Mac. Honestly speaking, it is a tough process for EI Capitan and you might receive errors when using the dmg file downloaded from Apple website.

Please don't worry. In this tutorial, we will share you all the necessary steps to make a bootable EI Capitan bootable USB on a Windows 10 PC. Here is a screenshot of our tutorial's output.

P.S. If you have a Mac, then please follow this official guide to create EI Capitan USB installer on macOS by using createinstallmedia command: https://support.apple.com/en-us/HT201372

sudo /Applications/Install OS X El Capitan.app/Contents/Resources/createinstallmedia --volume /Volumes/USBVolume --applicationpath /Applications/Install OS X El Capitan.app

Preparation

Please get started, there are a few things you should prepare for.

First, a USB drive with at least 16 GB storage as the installation file of EI Capitan (.dmg) is over 5.5GB. USB 3.0 is more recommended as it has faster reading and writing speed. This will save a lot of time.

Secondly, download EI Capitan (10.11.6) DMG file from this link: This is the modified version of Apple's dmg file dedicated for USB booting.

Warning: The download file hosted on Apple.com (InstallMacOSX.dmg) will only work on Mac platform. For creating installation media on Windows, please use the above link instead. The dmg file provided by Apple contains a .pkg file in DMG archive, which will result failure if you are using it on a PC.

It was 2009 when Apple last released a new operating system on physical media. Things have proceeded remarkably smoothly since version 10.7 switched to download-only installers, but there are still good reasons to want an old, reliable USB stick. For instance, if you find yourself doing multiple installs, a USB drive may be faster than multiple downloads (especially if you use a USB 3.0 drive). Or maybe you need a recovery disk for older Macs that don't support the Internet Recovery feature. Whatever the reason, you're in luck, because it's not hard to make one.

Bootable Os X El Capitan

As with last year, there are two ways to get it done. There's the super easy way with the graphical user interface and the only slightly less easy way that requires some light Terminal use. Here's what you need to get started.

• A Mac that you have administrator access to, duh. We've created El Capitan USB stick from both Yosemite and El Capitan, but your experience with other versions may vary.
• An 8GB or larger USB flash drive or an 8GB or larger partition on some other kind of external drive. For newer Macs, use a USB 3.0 drive—it makes things significantly faster.
• The OS X 10.11 El Capitan installer from the Mac App Store in your Applications folder. The installer will delete itself when you install the operating system, but it can be re-downloaded if necessary.
• If you want a GUI, you need the latest version of Diskmaker X app. Version 5 is the one with official El Capitan support.
• Diskmaker X is free to download, but the creator accepts donations if you want to support his efforts.

The easy way

Once you've obtained all of the necessary materials, connect the USB drive to your Mac and run the Diskmaker X app. The app will offer to make installers for OS X 10.9, 10.10, and 10.11, and it should run on OS X versions all the way back to 10.7—support for 10.6 was dropped in the most recent release.

Diskmaker X has actually been around since the days of OS X 10.7 (it was previously known as Lion Diskmaker), and it's still the easiest GUI-based way to go without intimidating newbies. If you're comfortable with the command line, it's still possible to create a disk manually using a Terminal command, which we'll cover momentarily.

Select OS X 10.11 in Diskmaker X, and the app should automatically find the copy you've downloaded to your Applications folder. It will then ask you where you want to copy the files—click 'An 8GB USB thumb drive' if you have a single drive to use or 'Another kind of disk' to use a partition on a larger drive or some other kind of external drive. Choose your disk (or partition) from the list that appears, verify that you'd like to have the disk (or partition) erased, and then wait for the files to copy over. The process is outlined in screenshots above.

The only slightly less-easy way

Create Windows 10 Bootable Usb

If you don't want to use Diskmaker X, Apple has actually included a terminal command that can create an install disk for you. Assuming that you have the OS X El Capitan installer in your Applications folder and you have a Mac OS X Extended (Journaled)-formatted USB drive named 'Untitled' mounted on the system, you can create an El Capitan install drive by typing the following command into the Terminal.

sudo /Applications/Install OS X El Capitan.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applicationpath /Applications/Install OS X El Capitan.app --nointeraction

Create El Capitan Bootable Usb From Windows 10

The command will erase the disk and copy the install files over. Give it some time, and your volume will soon be loaded up with not just the OS X installer but also an external recovery partition that may come in handy if your hard drive dies and you're away from an Internet connection.

Create Bootable Usb

Whichever method you use, you should be able to boot from your new USB drive either by changing the default Startup Disk in System Preferences or by holding down the Option key at boot and selecting the drive. Once booted, you'll be able to install or upgrade El Capitan as you normally would.
