Looking to install macOS on an external hard drive for testing, backup, or running a second system? This step-by-step guide shows you exactly how to install macOS Monterey on an external drive using built-in tools on your Mac. Whether you're using an HDD, SSD, or a fast flash drive, this method works as long as the drive meets the system requirements.

Before starting, make sure your external hard drive has at least 64GB of available space and is properly formatted. The video starts by guiding you through Disk Utility, where you'll learn how to erase and prepare the drive using the 'Mac OS Extended (Journaled)' format with a 'GUID Partition Map'. This is crucial to ensure the macOS installer recognizes the drive during installation.

Next, you’ll see how to download the macOS Monterey installer directly from the App Store. After verifying that your Mac supports Monterey, the video walks through selecting the installer and preparing for installation. Once the installer is downloaded, you'll be shown how to navigate through Finder, choose the correct disk, and set the right user and permissions to begin the macOS setup process on your external device.

It's especially important to keep your Mac plugged into a power source during this process, particularly if you're on a MacBook, to prevent any interruption that could corrupt the installation. With careful attention to detail, you can successfully boot and run macOS Monterey from your external drive, giving you a portable and flexible macOS environment that won’t affect your main system.
