How to create bootable macOS 13 Ventura installer on a USB drive

Often, a bootable macOS Ventura USB installer can come in handy. For example, you can use the drive to install fresh macOS on as many Macs as you like without having to repeatedly download the large 12 GB file to each machine. On top of that, it'll help you reinstall macOS and fix your Mac if it doesn't power on for some reason. 

With new macOS Ventura released on October 24, 2022, you might want to have a backup — a bootable installer of your previous macOS, so you can roll back to it if you don’t like Ventura. Same can be done with any macOS version that comes after Ventura. 

In this guide, we’ll show you how to create a bootable installation drive with macOS Ventura.

What is a bootable USB or external drive?

To make sure we're on the same page, let's quickly mention what a bootable macOS Ventura USB drive is. Bootable USB (also external drive) is a disk that we use to boot up a system for the installation of an Operating System. 

Things you need to make a bootable macOS Ventura USB

Before we get started, here are the three essential things you need to create a bootable USB:

1. A 16 GB or more USB flash drive formatted as Mac OS Extended
2. Stable internet connection
3. Minimum one hour of free time.

Where to get macOS Ventura installer files 

Go to the App Store app and search for macOS Ventura. 

When the results are displayed, choose Ventura and then click “Get.” Hold off until it downloads. The installation will start once it is finished. Be sure to stop it right away.

Alternatively, you can download the installer from the Software Update section once the update is available.

Your Applications folder now contains a copy of the installer. For making the installer, you now have two options. We'll take a look at both. 

How to format your USB flash drive 

The drive will be erased. So, be sure to transfer any important files first to your Mac if it has any. 

To make a bootable installer for macOS, format your drive as Mac OS Extended as follows:

1. Connect your USB drive to your Mac
2. Open Disk Utility (in the Finder, click Go > Utilities > Disk Utility), choose MacOS X Extended (Journaled)
3. modify the name to Installer, and then click Erase.
