DiskMaker X (formerly Lion DiskMaker) is an application built with AppleScript that you can use with many versions of OS X to build a bootable drive from OS X installer program (the one you download from the App Store). As soon as you launch the application, it tries to find the OS X Install program with Spotlight. Then, it proposes to build a bootable install disk and make it look as nice as possible. It’s the easiest way to build an OS X Installer in a few clicks ! Then you can use the Install drive to fully re-install the OS on a freshly formated drive, or install it on your many Macs without re-downloading the full installer.

7. Now the app will ask you about your thumb drive, and it will tell you that will be completely erased before copying OS X El Capitan onto it…
8. Now the app will format your flash drive and ask you for your admin password. Once you enter your admin password, DiskMaker X will start copying the necessary El Capitan files onto your flash drive.
