How to Create macOS Monterey Bootable USB using Terminal

So, here is a quick review of all the procedures to perform the creation:

Download macOS Monterey
Insert USB drive and perform the partition
Format the USB and make it bootable

Download macOS Monterey

First, go to the Apple App Store and download macOS Monterey. From the app store, you will only download the installer. Which will later help you to download macOS Monterey. For now, users who have a subscription to the developer’s account are enabled to download macOS Monterey.

In the future, everyone can download and use the installer. If don’t have access to the developer’s account subscription, then the link below will help you to download InstallAssistant.pkg. One of the great things about the InstallAssistant.pkg is that it will download macOS 12 directly from the Apple server.

macOS 12 Beta Version Download Version Build App Avail? Date

InstallAssistant.pkg 12 21A5248p 17.0.7 YES 6/7/21

Still, if you can continue with InstallAssistant.pkg or download links are not working for you or you can’t use it on your system then download macOS Monterey in ISO file from here.

Format USB

Now, you will need to format your USB drive. Before formatting your USB drive make sure you have taken out all the important files.

Hold the Command+Space keys and search for Disk Utility. Inside the Disk Utility, you will find the USB Flash Drive under in External Files section. Select the USB Flash Drive and click on Erase. Here you will need to format the flash drive.

You will need to give it a Name, select the Format as Mac OS Extended (Journaled) and Scheme as GUID Partition Map. Selecting the Scheme as APRFS won’t work, only GUID Partition Map will do the job for you.

Create bootable USB

In this step, launch your Terminal and type the command given below:

Sudo /Applications/Install\ macOS\ 12\ Beta.app/Contents/Resources/createinstallmedia –volume /Volumes/Untitled\ 2

Remember that your command will need changes according to your macOS version. Here I am using the beta version, if you are using other versions then you will need to type that version.

To make it simple: Right-click on the macOS Installer and Show Content Package>Contents>Resources then find the createinstallmedia. Now, type sudo and drag the createinstallmedia in Terminal.

Should sound like, –volume /Volumes/ VolumeName

From now on, the creation will take place. It might take a while, wait and your USB drive is ready.

Final Words

Using Terminals in macOS and Command Prompt in Windows OS is the best and easiest way to create a bootable USB drive. Remember, using USB 3.0 for making a bootable macOS Monterey is way better than USB 2.0.
