One of the easiest ways to create a bootable installer disk for macOS is to use DiskMaker X, a free and popular app that can build a bootable drive from any macOS installer program that you download from the App Store. In this article, we will show you how to download and use DiskMaker X 9.0, the latest version that supports macOS Catalina, Mojave, High Sierra, and Sierra.
What is DiskMaker X and why you might need it
DiskMaker X (formerly Lion DiskMaker) is an application built with AppleScript that can create a bootable installer disk for any version of OS X or macOS from OS X Lion (10.7) to macOS Catalina (10.15). It works by copying the contents of the macOS installer program that you download from the App Store to an external drive or volume, such as a USB flash drive, a hard drive, or an SD card. It also makes the disk look as nice as possible by adding a custom icon and label.
You might need DiskMaker X if you want to:
Install or reinstall macOS on your Mac without relying on an internet connection or a recovery partition
Install or reinstall macOS on multiple Macs without downloading the installer each time
Install or reinstall an older version of macOS that is not available from the App Store or macOS Recovery
Create a backup or emergency disk that can boot your Mac and access various utilities
What are the requirements and limitations of DiskMaker X
To use DiskMaker X, you will need:
A Mac running OS X Yosemite (10.10) or later
A macOS installer program downloaded from the App Store (the app will try to find it automatically with Spotlight)
An external drive or volume with at least 14 GB of available storage, formatted as Mac OS Extended (Journaled)
