“Creating a bootable macOS Sierra USB drive is very easy. All you need is a Mac, as the tools provided for the process are only available on OS X and macOS, and a USB drive with a capacity of 8GB or more,” Bamburic writes. “I will also explain how to use a dedicated third-party tool, in case you decide that this option suits you better.”
“But first you have to download the setup file from App Store,” Bamburic writes. “Apple offers a dedicated tool in OS X and macOS specifically for the purpose of creating a bootable USB drive. Unlike most tools that ship with the OS, it is not accessible directly from Launchpad. However, it can be accessed through Terminal, which you will have to open for this part of the process.”
