Creating a Bootable macOS Sierra Installer Drive with Disk Creator

Are you tired of downloading the same operating system to each of your Macs? Do you have multiple computers that need to be upgraded or reinstalled with macOS Sierra? Creating a bootable external drive can save you time and effort. In this article, we'll show you how to make a macOS Sierra external USB boot disk using Disk Creator.

The process is straightforward and only requires a few minutes of your time. You can use a free app called Install Disk Creator or the Terminal command line tool if you prefer. We'll cover both methods below.

First, make sure you have a drive with enough space to hold the installer software. The macOS Sierra installer takes up nearly 5GB of storage space, so choose a drive that has at least 8GB of free space. You can use a USB flash drive or a hard drive for this purpose.

Next, download the macOS Sierra installer from the App Store. If it automatically launches after download, quit the installer. Look for macOS Sierra in the list of apps you've purchased and click on the Download button to download the installer again.

Once downloaded, launch the App Store app and look for macOS Sierra in the store. Click on the Download button, and your Mac will download the installer to your Applications folder. If it automatically launches after download, quit the installer.

Now that you have the installer software, follow these steps:

1. Open Terminal and type `sudo /Applications/Install\ macOS\ Sierra.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled` (change 'Untitled' to the name of your drive).

2. Press Enter to execute the command.

3. The drive will be reformatted automatically as part of the process.

That's it! Your external USB boot disk is now ready to use. You can insert it into any Mac and restart the computer while holding down the 'Option' key. Select the external drive from the startup disk menu to start the installation process.

Using Disk Creator is a straightforward way to create a bootable macOS Sierra installer drive. If you're not comfortable using Terminal, there are a couple of free apps you can use instead.

Remember to always back up your data before installing any new operating system. Creating a bootable external drive can save you time and effort in the long run, especially if you have multiple Macs that need to be upgraded or reinstalled with macOS Sierra.
