Create a macOS High Sierra 10.13 USB Stick

There are several different ways to do a clean macOS High Sierra, also known as macOS 10.13, installation. One of simplest and easiest ways is to install via a USB stick. You don’t need to buy a special USB stick nor do you have to purchase a special program to make an macOS 10.13 High Sierra USB Install Stick.

Create a USB Install Stick for macOS 10.13 High Sierra with these four easy steps:

  1. Ensure that you have the Install macOS High Sierra.app installer application in your Applications folder. If you don’t have it, you can download it from the App Store. You will need to look in the Purchased tab and click Download for macOS 10.13 High Sierra
  2. You will need plugin a 8GB or larger USB stick, preferably a USB 3.0 stick. This USB stick will be erased of all data. A faster USB stick will help speed up this step as well as decreasing the time that it will take for macOS 10.13 High Sierra to install.
  3. Open up Terminal, located in the Utilities folder, which is located in the Applications folder.
  4. Run the follow command as listed below:
sudo /Applications/Install\ macOS\ High\ Sierra.app/Contents/Resources/createinstallmedia  --volume /Volumes/partitionToEraseOnUSB --applicationpath  /Applications/Install\ macOS\ High\ Sierra.app

Now you can Quit Terminal and Eject your USB stick. You now have a fully function macOS 10.13 Sierra USB Stick.

Once you have created your macOS High Sierra USB stick, restart the Mac computer that you would like to erase and reformat. Just after you turn on the computer, hold down the Option key. You should now be able to select the drive that you would like to boot from. Select your newly minted macOS High Sierra USB stick. After a few minutes, you will now be able to use Disk Utility to Erase your internal SSD or hard drive and then re-install macOS High Sierra.
