The following tutorial will show you how easy and quick to create and make a Bootable Installation of the new MacOS 10.13 High Sierra using your external drivers (USB) under Mac OS X.
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,…).
Step 1: Of course, you firstly need to download the new High Sierra from Apple store for free.
If High Sierra is not accessible to download from Apple Store, this alternative source is absolutely helpful.
After the downloading is accomplished completely, you should see the High Sierra installation icon from LaunchPad windows:

Step 2: Plug you USB into your Mac, run Disk Utility (Found in Applications/Utilities/) to format it.
Click on Erase button > Name your USB at a single name without space (Macdrug is an example) > Choose Master Boot Record at Format > Click on Erase.
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.
- Type Y, then press the Enter (Return key)
- The Coping installer files to disk may take five to ten minutes to finish.
DiskMaker X (formerly Lion DiskMaker) is now an application built with AppleScript that you can use with many versions of OS X/macOS to build a bootable drive from OS X/macOS installer program.
Done!
