How to Create a Bootable Installer of macOS on Your Mac

Are you an Oklahoma residential appliance installer looking to prepare for your license exam? Or perhaps you're an IT professional seeking to create a bootable installer of macOS on your Mac. Whatever the case, this article will guide you through the process step by step.

Creating a bootable installer of macOS can be useful if you want to install the operating system on multiple computers without having to download it each time or if you're unable to install a compatible macOS from the Finder or Recovery mode.

Prerequisites

Before creating your bootable installer, make sure that:

1. Your Mac is running macOS High Sierra or later, the latest version of macOS Sierra, or the latest version of OS X El Capitan.

2. You have a USB flash drive or other secondary volume with at least 14GB of available storage, formatted as Mac OS Extended.

Using Terminal to Create a Bootable Installer

Open Terminal, which can be found in the Utilities folder of your Applications folder. Enterprise administrators should download from Apple instead of using a locally hosted update server.

To create a bootable installer, type or paste one of the following commands into Terminal and press Return:

* `sudo /Applications/Install\ macOS\ 'version'\.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume` (replace `'version'` with the version number of the macOS you're downloading)

* `sudo /Applications/Install\ macOS\ 'version'\.app/Contents/Resources/createinstallmedia --applicationpath /Applications/Install\ macOS\ 'version'.app` (replace `'version'` with the version number of the macOS you're downloading)

Make sure to replace `MyVolume` with the name of your USB flash drive or other volume.

What You Need to Create a Bootable Installer

In addition to a compatible Mac and available storage space, you'll also need:

* A USB flash drive or other secondary volume formatted as Mac OS Extended

* The macOS installer downloaded from the App Store or your browser

By following these steps, you can create a bootable installer of macOS on your Mac. This process is primarily designed for system administrators and experienced users who are familiar with entering commands in Terminal.

Creating a bootable installer of macOS can be a useful tool for IT professionals and those looking to prepare for their Oklahoma residential appliance installer license exam. By following the steps outlined above, you'll be able to create a bootable installer on your Mac and install macOS on multiple computers without having to download it each time.
