Installing macOS High Sierra on a USB drive is a great way to upgrade your computer without having to deal with lengthy downloads or multiple installation attempts. Before you start, make sure you have the necessary requirements: OS X 10.12 or later, 2 GB of memory, and at least 8.8 GB of available storage.

If you're using an older device, check out Apple's list of supported Macs to ensure compatibility. Now that you're all set, let's get started with installing High Sierra on your computer.

Step 1: Download the macOS Installer

Download the new macOS 10.12 installer from the Mac App Store, but don't install it when it finishes downloading. This will save you time and effort in the long run. The download is approximately 5 GB, so be prepared for a longer wait on slower internet connections.

Step 6: Install High Sierra on Your Computer

Once downloaded, close out of any installation screens that may pop up. If you do, it will automatically erase the file on your USB drive when your system restarts. Instead, follow these steps to install High Sierra on your computer:

With a bootable USB stick, you can easily upgrade multiple computers without having to download the installer separately for each machine.

In addition to upgrading your Mac, macOS High Sierra offers several exciting features, including Apple Pay integration in Safari, unlocking your Mac with an Apple Watch, and syncing all your desktops and documents across devices. You'll also enjoy improved iMessage functionality and the ability to copy and paste between iOS 10 devices and Mac.

One of the most impressive features in High Sierra is Siri's upgraded capabilities, making it more powerful than its iOS equivalent. With macOS High Sierra now available for free download from the Mac App Store, you can experience these exciting new features and improvements firsthand.
