Apple uses its App Store to distribute its software, like new Macoperating systems. It’s convenient, but sometimes it can take a while fora download to finish. And if you have multiple Macs, it’s inefficient todownload the new OS to each and every Mac.

That’s why I like to make a bootable external drive for the sole purposeof installing the Mac operating system. When I need to tend to a bunch ofMacs, it’s much faster to use a bootable drive instead of going to eachMac, launching the App Store, searching for the operating system,downloading it (after entering my Apple ID), and then running theinstaller.

You can create a bootable USB flash drive with the macOS Sierra installerthat’s now available. The installer software will take up nearly 5GB ofstorage space. Here’s how to create a bootable macOS Sierra installerdrive.

Download the macOS Sierra installer

Launch the App Store app, then look for macOS Sierra in the store. (Here’sa link.) Click on the Download button, and your Mac will download theinstaller to your Applications folder. If it automatically launches afterdownload, quit the installer.

Look for macOS Sierra in the list of apps thatyou’ve bought, and click on the Download button. If it automaticallylaunches after download, quit the installer.

Get an external drive

You can use a USB flash drive or a hard drive with room for the installersoftware. I’ve used different drives with success, including a VisionTek120GB USB 3.0 Pocket Solid State Drive ($83 on Amazon) and an old 8GBIomega Micro Mini Hard Drive.

Don’t worry if the drive isn’t formatted for the Mac. The drive will bereformatted automatically as part of the process. Change the name of yourdrive to Untitled; you need to do this for the steps below.

The quick and easy way

The process detailed below involves the Terminal. If your really don’twant to use Terminal, there are a couple of free apps you can use.

Is your Mac up to date with the latest version of the Mac operating system (macOS or OS X)? Is it using the version required by some other product that you want to use with your Mac? Which versions are earlier (older) or later (newer, more recent)? To find out, learn which version is installed now.

If your macOS isn't up to date, you may be able to update to a later version.

Which macOS version is installed?

From the Apple menu  in the corner of your screen, choose About This Mac. You should see the macOS name, such as macOS Mojave, followed by its version number. If you need to know the build number as well, click the version number to see it.

This example shows macOS Catalina version 10.15 build 19A583.

Which macOS version is the latest?

Mac Os X Lion Simulator

These are all Mac operating systems, starting with the most recent. When a major new macOS is released, it gets a new name, such as macOS Catalina. As updates that change the macOS version number become available, this article is updated to show the latest version of that macOS.

If your Mac is using an earlier version of any Mac operating system, you should install the latest Apple software updates, which can include important security updates and updates for the apps that are installed by macOS, such as Safari, Books, Messages, Mail, Music, Calendar, and Photos.
