Installing Mac OS:

Formatting Your USB Flash Drive

You can only create a bootable installer for macOS on a Mac. If you’re using a flash drive that already has data on it, make sure to back up any important files as you’re going to erase everything in a moment.

Open Finder. Navigate to Applications > Utilities, and open up Disk Utility. You should see your flash drive under the External section in the left pane. After selecting it, click on the Erase button along the top.

Choose a friendly name (which you’ll use later), and make sure to choose Mac OS Extended (Journaled) for the format. Finally, click Erase and you’re done with this step.

macOS Disk Utility

Downloading the macOS Installer

To download the macOS installer, open the App Store and search for your version of macOS. Click on the Download button if you’re on High Sierra or earlier.

macOS Mojave is slightly different, as it opens up your System Preferences to download the installer. This is because one of the changes in Mojave is a new way of installing updates.

In either case, once the installer opens, quit it without continuing the installation.


Creating a Bootable USB Using Terminal

Terminal is the easiest way to create your bootable USB drive. Just replace the MyVolume portion of the command with the name you gave your drive in the Disk Utility step above.

Take note that the commands differ slightly for creating Mojave and High Sierra installers on older versions of macOS.

Mojave installer on Mojave or High Sierra:

sudo /Applications/Install\ macOS\ --volume /Volumes/MyVolume

Mojave installer on Sierra or earlier:

sudo /Applications/Install\ macOS\ --volume /Volumes/MyVolume --applicationpath /Applications/Install\ macOS\

High Sierra installer on High Sierra:

sudo /Applications/Install\ macOS\ High\ --volume /Volumes/MyVolume

High Sierra installer on Sierra or earlier:

sudo /Applications/Install\ macOS\ High\ --volume /Volumes/MyVolume --applicationpath /Applications/Install\ macOS\ High\


sudo /Applications/Install\ macOS\ --volume /Volumes/MyVolume --applicationpath /Applications/Install\ macOS\

El Capitan:

sudo /Applications/Install\ OS\ X\ El\ --volume /Volumes/MyVolume --applicationpath /Applications/Install\ OS\ X\ El\

Copy and paste the command you need above into your Terminal window and press the Return key. After entering your password, confirm you want to erase the USB drive by typing Y followed by Return.

Terminal will now erase and create your bootable USB drive, ready for you to boot from.
