MacOS – High Sierra Bootable USB If a new version of macOS becomes available, there are a lot of people who are considering a clean installation, a so-called clean install. This can come in handy when you restore the Mac factory settings.

What you need to create a bootable installer

  • A USB flash drive or other secondary volume formatted as Mac OS Extended, with at least 14GB of available storage
  • A downloaded installer for macOS Big Sur, Catalina, Mojave, High Sierra, or El Capitan

Download macOS

  • Download: macOS Big Sur, macOS Catalina, macOS Mojave, or macOS High Sierra
    These download to your Applications folder as an app named Install macOS [version name]. If the installer opens after downloading, quit it without continuing installation. To get the correct installer, download from a Mac that is using macOS Sierra 10.12.5 or later, or El Capitan 10.11.6. Enterprise administrators, please download from Apple, not a locally hosted software-update server.
  • Download: OS X El Capitan
    This downloads as a disk image named InstallMacOSX.dmg. On a Mac that is compatible with El Capitan, open the disk image and run the installer within, named InstallMacOSX.pkg. It installs an app named Install OS X El Capitan into your Applications folder. You will create the bootable installer from this app, not from the disk image or .pkg installer.

Use the 'createinstallmedia' command in Terminal

  1. Connect the USB flash drive or other volume that you're using for the bootable installer.
  2. Open Terminal, which is in the Utilities folder of your Applications folder.
  3. Type or paste one of the following commands in Terminal. These assume that the installer is in your Applications folder, and MyVolume is the name of the USB flash drive or other volume you're using. If it has a different name, replace MyVolume in these commands with the name of your volume.

Big Sur:*

Catalina:*

Mojave:*

High Sierra:*

El Capitan:

* If your Mac is using macOS Sierra or earlier, include the --applicationpath argument and installer path, similar to the way this is done in the command for El Capitan.


After typing the command:

  1. Press Return to enter the command.
  2. When prompted, type your administrator password and press Return again. Terminal doesn't show any characters as you type your password.
  3. When prompted, type Y to confirm that you want to erase the volume, then press Return. Terminal shows the progress as the volume is erased.
  4. After the volume is erased, you may see an alert that Terminal would like to access files on a removable volume. Click OK to allow the copy to proceed.
  5. When Terminal says that it's done, the volume will have the same name as the installer you downloaded, such as Install macOS Big Sur. You can now quit Terminal and eject the volume.

There are times when you may not want to use the App Store or the recovery mode to install macOS 10.13 High Sierra on your Mac. So Apple gives you the option of creating a bootable USB drive. You can use it anytime and anywhere to quickly get the operating system running on any compatible Mac. An Internet connection is not even required as everything you need is already on the drive.

Creating a bootable macOS 10.13 High Sierra USB drive is very easy. All you need is a Mac, as the tools provided for the process are only available on OS X and macOS, and a USB drive with a capacity of 8GB or more. I will also explain how to use a dedicated third-party tool, in case you decide that this option suits you better.

But first you have to download the setup file from App Store. Use this link to take you right to its landing page, or search for it manually in the App Store app. After the download is complete, Install macOS High Sierra will be available in your Applications folder. A setup wizard should have appeared by now -- you can close it.

Also, you should backup the contents of the USB drive that you are using for the process, as everything that is stored on it will be removed. And, of course, make sure that you read the instructions carefully before starting.

Apple's Way, All the Way

Apple offers a dedicated tool in OS X and macOS specifically for the purpose of creating a bootable USB drive. Unlike most tools that ship with the OS, it is not accessible directly from Launchpad. However, it can be accessed through Terminal, which you will have to open for this part of the process.

Here is what you need to do:

Make a bootable usb mac high sierra
  1. Connect the USB drive to your Mac
  2. Using Disk Utility (it is typically found in the Other folder, under Launchpad), format the USB drive as Mac OS Extended (Journaled), using the GUID Partition Mac scheme, and name it macOSHighSierra. This can be done from the Erase tab within the app; make sure that there are no multiple partitions (turn to the Partition tab to verify and correct this)
  3. Open Terminal (it is found in the same folder as the Disk Utility app)
  4. Use (paste) the following command: sudo /Applications/Install macOS High Sierra.app/Contents/Resources/createinstallmedia --volume /Volumes/macOSHighSierra --applicationpath /Applications/Install macOS High Sierra.app --nointeraction
  5. Type in your user password, when required, to start the process

Based on my experience, this is the best method of creating a bootable macOS 10.13 High Sierra USB drive. It delivers consistent results every time, and does not cause any issues.

Because it is barebones, the tool does not provide any indication as to how much time is left until the process completes. It usually takes around half an hour in my case, but this depends on the speed of the USB drive -- the faster it is the sooner this step is over.

The User-Friendly Tool

DiskMaker X (currently at version 7) is the more user-friendly tool for the job. It automates the process of creating a bootable macOS 10.13 High Sierra USB drive, requiring little input from you. And the results are virtually the same with the aforementioned method.

If you wish to use DiskMaker X to create the bootable macOS 10.13 High Sierra USB drive, here is what you need to do:

  1. Connect the USB drive to your Mac
  2. Open DiskMaker X and Select Use this copy to use the Install macOS High Sierra app from the Applications folder (Select Use another copy... if the setup file is in another folder)
  3. Select An 8 GB USB thumb drive. (Alternatively, select Another kind of disk if you want to use something else)
  4. If requested, from the given list, select the USB drive you are using for the process, and then select Choose this disk
  5. Select Erase then create the disk
  6. Select Continue
  7. Type in your user password when requested

Unlike the official tool baked in OS X and macOS, DiskMaker X also lets you know how long the process takes. Like I mentioned before, this depends largely on the speed of the USB drive that you have, so, ideally, you should use the fastest one available, in case time is of the essence.
