How to Create a Bootable USB Installer for macOS Sierra 'macOS Sierra bootable USB'

Creating a bootable USB installer for macOS Sierra is easier than you think, and it's a great way to ensure that you have a reliable copy of the operating system. Apple provides two methods for creating an install disk: using the Install Disk Creator or using the terminal command.

Method 1: Using Install Disk Creator

Install Disk Creator is a graphical user interface app that allows you to create an install disk with just a few clicks. To use it, follow these steps:

1. Download and install Install Disk Creator from the Mac App Store.

2. Connect your USB flash drive or external hard drive to your Mac.

3. Launch Install Disk Creator and select the device you want to use as the installer.

4. Select the macOS 10.12 Sierra installer from the Applications folder.

5. Click 'Create Installer' and wait for the process to complete.

Method 2: Using Terminal Command

If you prefer a more command-line approach, you can use the terminal command to create an install disk. To do this, follow these steps:

1. Open the Terminal app on your Mac.

2. Type the following command and press Enter: `sudo /Applications/Install\ macOS\ Sierra.app/Contents/Resources/createinstallmedia`

3. Select the device you want to use as the installer from the list of available devices.

4. Wait for the process to complete.

Regardless of which method you choose, your USB installer will be deleted when you install the operating system. However, you can always re-download and recreate the installer if needed.

Tips and Tricks

* For newer Macs, it's recommended to use a USB 3.0 drive to ensure faster installation times.

* If you have an 8GB or larger USB flash drive or external hard drive, you can use that as your installer device.

* Make sure you have administrator access to your Mac before attempting to create the install disk.

* It's a good idea to periodically re-download new Sierra installers and make new install drives if you plan to use the USB installer with newer Macs.

Creating a bootable USB installer for macOS Sierra is a simple process that can be completed using either the graphical user interface of Install Disk Creator or the terminal command. By following these steps, you'll have a reliable copy of the operating system that you can use to install and reinstall macOS Sierra as needed.
