How to Create a bootable macOS 10.13 High Sierra flash drive from the terminal


On September 25 this year, the new version of macOS 10.13 High Sierra was officially presented. The installer can be downloaded from the AppStore , its size is about 5 GB, but a 4 GB flash drive will not be enough for recording.


First of all, you need to download the installer , which after downloading will appear in the program folder. Now let's talk about how to create a bootable USB flash drive for Mac computers.


To do this, we need, as mentioned above, an 8 GB flash drive, pre-formatted in the HFS + GUID system.


In addition, you will need the system itself, or rather a computer with an installed Macintosh system, and the downloaded installer itself.


Using the " disk utility " program , we format our USB flash drive. Let's just call it "Untitled". Next, connect the erased flash drive to the computer, open the terminal, type the following command "sudo".


Next, we find our installer in the "programs" folder, right-click on it and select "show content" from the menu. In the installer, we find the required resources folder, which contains the file we need called "createinstallmedia". It is this file by dragging and dropping into the terminal window.


Then we continue the line, type "--volume". After that, drag our formatted flash drive into the terminal window, the line / Volumes / Untitled will appear, followed by a space and the next command "--applicationpath". And after that, you can transfer the entire installer to the terminal window.


As a result, we get a rather long command, let's give an example:


sudo / Applications / Install macOS High Sierra.app/Contents/Resources/createinstallmedia --volume / Volumes / Untitled --applicationpath

Next, the program will prompt you to format the USB flash drive, you must press the letter "y". The macOS 10.13 High Sierra installation flash drive will be written within 10-20 minutes and then you can safely use it. The recording time depends on the speed of your Mac's USB port and the speed of the USB drive itself.


This is one of the most reliable options for recording an installation flash drive for Apple computers . Here you cannot make a mistake, unlike if, for example, you type in the command manually. Have a good day.
