Instructions for creating a MacOS Sierra 10.12 installer


Apple has just released macOS Sierra 10.12 official version. You can update directly or for those who want to create a completely new USB installer to clean the device, you can follow the instructions in the following article.

Currently I see There are 3 ways to create a MacOS Sierra 10.12 installer. I will write down all 3 ways in order from easy to difficult. In essence, these three ways are the same.

  • Method 1 uses software to create the installer.
  • Method 2 uses the command line.
  • Method 3 is completely manual.

First, download the official MacOS Sierra 10.12 installer. Then use 1 of the following 3 ways to create an installation USB

Method 1: Use Install Disk Creator software.

– First download the software Install Disk Creator here

– Prepare 1 USB with capacity of 8gb or more

1. Run Disk Creator
2. Plug in the USB, remember that this USB will be white format.
3. Run Disk Creator, press “Select OS X Installer
4. Find the file Install macOS Sierra
5. Press the button Select the volume to become the installer and select the USB drive just now
6. Press “Create Installer” wait a few minutes depending on your USB speed.

7. Done ^_^

This is the simplest, easiest to understand, least error-prone way. However, if your usb is too slow, it can lead to time out and unsuccessful creation. Now you move to try method 2.

Method 2: Use the command line

Prepare:

  • 1 8GB capacity USB
  • macOS 10.12 installation file (download at the top of the post)
  • After downloading the installation file, you can extract a new file called “Install macOS Sierra.app“, you changed your name to Sierra.app (Press Enter to rename and then type Sierra. The .app extension is the default) Then copy it to the folder. Application of the machine (drag and drop to folder Application left hand side)

Start creating the installer:

  • Run Disk Utility (Click Launchpad type Disk then choose Disk Utilitly) Select the USB Disk on the left side of the screen, press the Erase button, leave the default name as UntitledFormat: OS X Extended (Journaled)Scheme: GUID Partion Mapthen press Erase, wait a few minutes for the USB format to finish, then press Done

  • Run Terminal: Copy this command line and paste it into Terminal then type your login password. (While typing the password, the machine does not show *** anything, just type it correctly)

sudo /Applications/Sierra.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applicationpath /Applications/Sierra.app --nointeraction

It will take from 4-5 minutes to 10 minutes depending on the speed of your USB disk for the code to run 100%, after that you have a USB installer for you. macOS Sierra congratulation!

A little explanation about the command: In the above command line, there are 2 places I highlighted in red:

  • Untitled: is the name of the USB. This, if in the Format step you change the name, you also change it in the above command
  • Sierra.app is the name of the installation file located in the directory Application

Method 3: Completely Manual

Prepare:
1. Download the installer
2. USB, SD Card, portable hard drive, .minimum capacity 8GB

Step 1: Show hidden files. Run the following command to show hidden files
