Create A macOS USB Flash Drive Installer



Terminal
Unlike Microsoft, Apple has made it difficult for the average user to make a USB flash drive installer to macOS on a supported Mac.

Use Disk Utility (see Utilities folder in your Applications folder) to format a USB 2.0 flash drive of at least 8 GB with the following as per the screenshot below.

For each version of macOS listed here, you have to copy the entire code listed and paste it in the Terminal application (see Utilities folder in your Applications folder). Follow the directions and you will end up with a USB flash drive installer that you can use to do a fresh install or re-install macOS on any supported Mac.

Note:


Yes, I know that macOS 10.10 and 10.11 are referred to as OS X. Personally, I prefer using macOS because it is less confusing.
