Since today is the release of macOS Monterey, I figured I’d post a quick one-liner (well, really two one-liners) to make a macOS Monterey install USB drive.
<ol>
<li>Download the full installer for macOS 12.0.1 <code>softwareupdate --fetch-full-installer 12.0.1</code>
</li>
<li>Once downloaded, we need to run the createinstallmedia command to copy the data to an external drive that will contain the bootable USB installer. (It’s assumed you already have a partition created for this, but please note, this command will format the partition and you will lose any data on the partition). <code>sudo /Applications/Install\ macOS\</code> <a target="_blank" href="http://Monterey.app/Contents/Resources/createinstallmedia"><code>Monterey.app/Contents/Resources/createinstallmedia</code></a> <code>--volume /Volumes/MontereyInstaller/ --nointeraction</code>

Since today is the release of macOS Monterey, I figured I’d post a quick one-liner (well, really two one-liners) to make a macOS Monterey install USB drive.

1. Download the full installer for macOS 12.0.1  
    `softwareupdate --fetch-full-installer 12.0.1`
    
2. Once downloaded, we need to run the createinstallmedia command to copy the data to an external drive that will contain the bootable USB installer. (It’s assumed you already have a partition created for this, but please note, this command will format the partition and you will lose any data on the partition).  
    `sudo /Applications/Install\ macOS\` [`Monterey.app/Contents/Resources/createinstallmedia`](http://Monterey.app/Contents/Resources/createinstallmedia) `--volume /Volumes/MontereyInstaller/ --nointeraction`
