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.

If you’ve already upgraded your Mac to Sierra, the installer is removedfrom the Applications folder. You can download it again if you go toPurchased in the App Store. 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.
