DiskMaker X (formerly Lion DiskMaker) is an application built with AppleScript that you can use with many versions of OS X/macOS to build a bootable drive from OS X/macOS 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/macOS 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.

WARNING! The whole contents of the drive (including every other volume from this drive) will be erased! Please backup any data on another disk if necessary.

DiskMaker is freeware. However, if you enjoy using DiskMaker and would like to help support its development, please consider making a donation.
