New Mexico Plumber Installer License Prep Class for Mac Install

As a plumber installer in New Mexico, you may need to prepare your Mac computer for installation of specific software or operating systems. One such task is creating a bootable installer using Terminal. In this article, we will guide you through the steps to create a bootable installer on your Mac.

Prerequisites

Before starting, ensure that your Mac meets the system requirements for the macOS version you want to install. Additionally, make sure you have a compatible USB flash drive or secondary volume with at least 14GB of available storage formatted as Mac OS Extended.

Creating a Bootable Installer Using Terminal

To create a bootable installer using Terminal, follow these steps:

1. Open Terminal on your Mac. You can find it in the Utilities folder within the Applications folder.

2. Type or paste one of the following commands into Terminal and press Return:

```

sudo /Applications/Install\ macOS\ 'version'.app/Contents/Resources/createinstallmedia -n MyVolume -volume /Volumes/MyVolume

```

Replace `'version'` with the version of macOS you want to install, and `MyVolume` with the name of your USB flash drive or secondary volume.

3. When prompted, type `Y` to confirm that you want to erase the volume, then press Return.

4. Terminal will not display characters as you type.

Alternative Method: Downloading a macOS Installer

Alternatively, you can download a macOS installer using the App Store or your browser. You must have a compatible Mac with macOS High Sierra or later, the latest version of macOS Sierra, or the latest version of OS X El Capitan to download a full installer.

Creating a bootable installer on your Mac using Terminal is a convenient way to install macOS on multiple computers without having to download the installer each time. This advanced step is primarily intended for system administrators and experienced users who are familiar with entering commands in Terminal. By following these steps, you can ensure that your Mac is prepared for installation of specific software or operating systems.
