MacOS High Sierra has just been released officially. Too many users are looking for the best way to make a bootable installation drivers instead of a bootable DVD. Take the following tutorial to do it in just some minutes.

This is not a something complicated because I just show you how I did on my MacOS Sierra (the whole processes must be the same on (El Capitan, Yosemite,…).

It then takes few seconds to ease and create a new disk with the name of “Macdrug”

Step 3: Launch terminal (Found in Applications/Utilities/), then enter the following command line:

sudo /Applications/Install\ macOS\ High\ Sierra.app/Contents/Resources/createinstallmedia --volume /Volumes/Macdrug

Be noticed at this part:  --volume /Volumes/Macdrug    that Macdrug is my USB name and must be replaced by yours if it is different. A single name without space must work by the above command line.

The administrator password (the user and password you normally use to log into your Mac) must be provided.
