What you need to create a bootable installer

Mac Os High Sierra Usb Installer Windows

  • 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:*

High

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.

A bootable installer doesn't download macOS from the internet, but it does require an internet connection to get firmware and other information specific to the Mac model.

Like its predecessors, users can upgrade to macOS High Sierra via the Mac App Store. For most users, this is the easiest and simplest way to upgrade to Apple’s latest Mac operating system. But sometimes it’s nice to have a bootable macOS High Sierra USB installer, which lets you install High Sierra from scratch on a new or wiped drive, troubleshoot installation issues, or save time and bandwidth if you need to upgrade multiple Macs.
The bad news is that Apple no longer distributes macOS physically via an installer DVD. The good news, however, is that users can easily create their own bootable macOS High Sierra USB installer with just a few quick steps. Here’s how to do it.
Note: macOS High Sierra is currently in beta. The instructions below cover how to create a bootable High Sierra installer for this beta, and will not work without modification on the final public release. We will update this article when macOS High Sierra is publicly released later this year.

Step 1: Download macOS High Sierra from the Mac App Store

The first step to create your own bootable macOS High Sierra USB installer is to download the app-based installer Apple provides via the Mac App Store. For the current beta, users will find High Sierra in their Purchased tab after registering their Mac. When High Sierra is finally released, you’ll be able to find it linked in the sidebar of the Mac App Store homepage.
The macOS High Sierra download is relatively large at just over 5GB, so it may take some time to download depending on the speed of your Internet connection. Once it’s done, the High Sierra installer app will automatically launch.
This app is how you would normally upgrade your Mac, but we don’t need to run it now for the purposes of creating our bootable USB installer. Therefore, close the installer app by pressing Command-Q on your keyboard.

Step 2: Prepare Your USB Drive

Createinstallmedia High Sierra Terminal

To create a bootable macOS High Sierra USB installer, you need a USB 2.0 or USB 3.0 drive with a capacity of at least 8GB. Creating the installer will erase all data on the USB drive, so make sure to back up any existing data that may be on the drive.
Plug the USB drive into your Mac and launch the Disk Utility app. You can find Disk Utility by searching for it in Spotlight or in the Applications > Utilities folder.
In Disk Utility, select your USB drive from the list on the left. Next, click Erase from the toolbar. We need to give the USB installer a temporary name in order for the Terminal command below to work. If you plan to just copy and paste the Terminal command, name your USB drive “HighSierra.” You’re free to change it, but you’ll need to modify the command to reference the new name.
Ensure that the “Format” drop-down is set to Mac OS Extended (Journaled) and that “Scheme” is set to GUID Partition Map. When you’re ready, click Erase to wipe the drive.

Step 3: Create the Bootable macOS High Sierra USB Installer

Once your USB drive is erased, launch the Terminal app (located by default in the Applications > Utilities folder). Copy and paste the following command into the Terminal window and press Return on your keyboard to execute it:
sudo /Applications/Install macOS 10.13 Beta.app/Contents/Resources/createinstallmedia –volume /Volumes/HighSierra –applicationpath /Applications/Install macOS 10.13 Beta.app –nointeraction
This is a sudo command, so you’ll need to enter your admin password when prompted. Terminal will then access the createinstallmedia tool built in to the High Sierra installation bundle. You can monitor the progress of the process via the Terminal window.
The time it takes to complete the creation process will vary based on the speed of your USB drive. In most cases, it shouldn’t take more than 5 minutes. Once the process is complete, you’ll see the Terminal window display “Done.”
Your new bootable macOS High Sierra USB Installer will now mount to your Mac, ready for use.

Step 4: Install macOS High Sierra via USB

High Sierra Createinstallmedia

Once you have your bootable macOS High Sierra USB installer, you can use it to install High Sierra on compatible Macs in one of two ways. First, you can connect it to a running Mac and launch the upgrade installer. This will produce the same result as upgrading via the Mac App Store, but it saves you from having to download the High Sierra installer application first.
Second, you can use your USB drive to perform a clean install of High Sierra. To do so, first power off the Mac you wish to upgrade and plug in your USB drive. Next, hit the Mac’s power button to turn it on and then press and hold the Alt/Option key on your keyboard as soon as you hear the Mac’s startup chime.
Keep holding Alt/Option until you see the Startup Manager appear. Use the cursor or the arrow keys on your keyboard to select your bootable High Sierra USB installer. The Mac will now boot to the High Sierra installer and, because it is running off of the USB drive, it can access and erase your Mac’s internal drive. Once erased, the installer will perform a clean install of High Sierra on your drive (just make sure to back up before performing a clean install!).
