To install macOS or OS X from USB, you need to create a bootable install USB drive for Mac operating system. This tutorial will introduce you three ways to create bootable USB drive for macOS High Sierra, macOS Sierra, Mac OS X El Capitan, Yosemite, Mavericks and more.

Use 'createinstallmedia' Command in Terminal

The most recommendable way to create a bootable install USB drive for Mac OS is using 'createinstallmedia' Command with Terminal application.

Step 1: Download macOS or OS X

The first thing to do is to download the Mac operating system that you need. To install the latest Mac OS, for example, macOS High Sierra, you can search and download the installer from App Store.

To download the older Mac OS X version, you can go to App Store > Purchases to download the Mac OS X El Capitan, Yosemite, Mavericks that has been previously downloaded.

However, Apple has decided that macOS Sierra and later will no longer be listed in Mac App Store's Purchased. To download the installer of macOS Sierra, go to Apple Support.

Note: After downloading the Mac OS installer, do not install the OS but quit the installer.

Step 2 Get A USB Drive with Sufficient Storage

You should have a USB drive with at least 8 GB of storage and insert the USB drive into your Mac. If you need to create a bootable USB drive of macOS High Sierra, 16 GB USB flash drive is suggested. In fact, USB drives with larger storage, like 32 GB to 64 GB, tend to show better performance.

IMPORTANT: The contents of the drive will be erased after creating a bootable installer drive. Therefore, make sure there is nothing important on your flash drive before you continue with the following steps.

Step 3 Check the Name of Your Flash Drive

The following command is to create a bootable copy of Mac OS installer on a USB drive named FlashInstaller. If your USB drive has a different name, replace FlashInstaller in the command with the name of your USB drive. If you don't want to modify the command, change the name of your flash drive into FlashInstaller.

Step 4 Create A Bootable USB Drive of macOS/OS X

Launch Terminal enter the following command according to the version of Mac operating system that you are dealing with.

macOS High Sierra Installer

sudo /Applications/Install macOS High Sierra.app/Contents/Resources/createinstallmedia --volume /Volumes/FlashInstaller --applicationpath /Applications/Install macOS High Sierra.app --nointeraction

macOS Sierra Installer

sudo /Applications/Install macOS Sierra.app/Contents/Resources/createinstallmedia --volume /Volumes/FlashInstaller --applicationpath /Applications/Install macOS Sierra.app --nointeraction

OS X El Capitan Installer

sudo /Applications/Install OS X El Capitan.app/Contents/Resources/createinstallmedia --volume /Volumes/FlashInstaller --applicationpath /Applications/Install OS X El Capitan.app –nointeraction

OS X Yosemite Installer

sudo /Applications/Install OS X Yosemite.app/Contents/Resources/createinstallmedia --volume /Volumes/FlashInstaller --applicationpath /Applications/Install OS X Yosemite.app –nointeraction

OS X Mavericks Installer

sudo /Applications/Install OS X Mavericks.app/Contents/Resources/createinstallmedia --volume /Volumes/FlashInstaller --applicationpath /Applications/Install OS X Mavericks.app –nointeraction

How to open dmg files windows 10. For example, a.pkg file can be installed to your MacBook or iMac, while a.dmg file allows you to clone existing drives in order to move information and other content around between machines.Of course, if someone gives you a.dmg file and you work primarily within Windows, you may be concerned about how to actually open these drive images on your computer.

Tip: If you didn't download the installer from Mac App Store, you must modify the file path after 'applicationpath'.

After pasting the command on the Terminal, hit Enter key. You'll be asked to enter your Mac's password. Enter the password and hit Enter.

Then you need to check the name and path of your USB drive. If it is correct, press 'y' then hit 'Enter'. The Mac will begin to create a bootable install drive for macOS High Sierra, macOS Sierra, Mac OS X El Capitan/Yosemite/Mavericks. When it is done, Terminal will shows 'Done'.

DiskMaker X: When you launch the application, it will try to find the downloaded macOS or OS X installers program on your Mac. And you just need to follow its on-screen instructions to create a bootable USB drive by clicking a few buttons.

Install Disk Creator: Once you run the application, select a USB drive, choose a Mac OS installer, and click Create Installer to begin to create an install USB drive.

Disk Utility to Create a Bootable macOS/OS X Installer

Before using createinstallmedia command, people used to use Disk Utility to create a bootable installer drive manually. But the process is much more complicated than the Terminal method. So Apple also suggests you make a bootable install drive via Terminal.

Just in case that you don't want to use Terminal, you may follow these steps to build a USB drive for Mac OS X or macOS.

Launch Disk Utility as found in Applications/Utilities and go to the Restore tab.

Drag BaseSystem.dmg to the Source field and your external disk to the Destination and click Restore.

This will mount your new OSX 10.9 external disk and name it OSX Base System – but we need to add the packages.

Fix the Packages

Couple of things to fix in the newly created boot disk, remove the Packagealias at System/Installation/ folder

Now from the previously mounted InstallESD.dmg copy over the Packages folder to the same location where we just removed the alias above.

Will take a while as it holds all the install packages.

Job done now you can boot from the OSX 10.9 disk.

Make the Visible back to Invisible

If you want all to return back to normal and hide the system files run a couple more commands in the Terminal

How to create the OSX 10.9 Mavericks Bootable Drive just via Terminal

Just for the crazy ones……after Mavericks is downloaded….and again this assumes you external disk is named BootDisk

Mount the InstallESD.dmg buried deep in the app

Swap to the newly mounted image

This puts you back in the Finder in front of the newly mounted InstallESD.dmg, go back to Terminal and clone the BaseSystem.dmg to the remote USB drive

This will change ‘BootDisk‘ to ‘OS X Base System‘

Remove the existing Packages alias link from the newly restored image

Copy the full OSX Mavericks Packages over to the new image….takes a while

And there it is! – to eject the new bootable USB OSX Mavericks 10.9 disk ‘cd’ to home and eject

Now you can boot up from your newly bootable disk and either Install OSX10.9 on another device or use the Terminal/Disk Utility or Firmware Password Utilities on another device.
