A bootable installer is a special type of media that can be used to reinstall operating system or fix system issues that never be solved in usual way. When there is something with your Mac, or you urgently need to upgrade your Mac to the latest version of macOS, a bootable installer could be a great help.
This tutorial tells you how to easily create a bootable installer for macOS on both Windows and Mac.
Before getting started, you should know there is only two types of installation media for macOS. One is the official macOS installation app, which is only available from Mac App Store. The other is macOS dmg file, which is made by third-party developers or system administrators.
Part 1. Create a Bootable Installer for macOS on Mac
macOS is the native operating system for all Mac computers. And Apple provides an official tool to create bootable USB installer from macOS installation app with the help of Terminal command, which is totally free. In addition, it is also possible to make a bootable macOS installer from DMG file. We will show examples for both tactics.
Create a Bootable Installer for macOS with Official App
This is the most reliable way to make bootable macOS installer on Mac as it is backed by Apple. It is completely free and no need to download additional software for this purpose.
First, download macOS from Mac App Store. Just launch App Store app on your Mac and search for the macOS name. However, only the most recent versions are available for download, including Big Sur, Catalina, Mojave and High Sierra. After that, click the Get button (Big Sur as example) to download the installation app on your Mac.
The downloading process will take more than 15 minutes as the file size is pretty big (Over 8GB). When it is completed, you will see a Install macOS [version name] app in Application folder.
Now, insert an USB drive into Mac. If everything goes fine, you will see the drive name in left sidebar of Finder app. Then, open Terminal app and type the following command to find the actual volume name of USB drive, which will be used in next step: ls /Volumes/
In above example, the volume name of my USB drive is Big Sur.
Finally, copy one of the following commands to Terminal and change the volume name. Click Enter to start creating a bootable installer for macOS.
Big Sur: sudo /Applications/Install macOS Big Sur.app/Contents/Resources/createinstallmedia --volume /Volumes/Big Sur
Catalina: sudo /Applications/Install macOS Catalina.app/Contents/Resources/createinstallmedia --volume /Volumes/Big Sur
Mojave: sudo /Applications/Install macOS Mojave.app/Contents/Resources/createinstallmedia --volume /Volumes/Big Sur
High Sierra: sudo /Applications/Install macOS High Sierra.app/Contents/Resources/createinstallmedia --volume /Volumes/Big Sur
You have to wait at least 10 minutes for the above task to be finished. After that, you can use the bootable USB installer for macOS reinstallation, downgrade or upgrade.
