This is the Install DMG of OS X El Capitan, downloaded from Apple's website just before this upload. This is for archiving purposes, just in case Apple decides to remove the download, so people can still download this in the future. Plug your drive into any eligible Mac to install El Capitan. To do this, shut down the mac you want to install El Capitan onto. Plug the Flash Drive into the computer. Reboot by pressing the power button and holding down the ⌥ Option key while it starts up.
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.
Use the 'createinstallmedia' command in Terminal
Download the macOS Installer file from the App Store 2 (OS X El Capitan and Sierra is downloadable from Apple's website). When download finishes, find the app, right-click and select 'Show Package Contents'. Install Dmg File In Virtualbox Windows 7 Download Mac OS X El Capitan on Virtualbox on Windows.

- Open Terminal, which is in the Utilities folder of your Applications folder.
