Making a macOS Mojave USB key

Software
  1. Download Mojave from the Mac App Store.

  2. Use Disk Utility.app or diskutil(1) to create a GUID Partition Map and format with Mac OS Extended (Journaled) on a target 8 GiB+ USB key.

  3. Run these commands:

$ cd "/Applications/Install macOS Mojave.app/Contents/Resources"
$ sudo ./createinstallmedia --volume /Volumes/YOURKEY \
      --nointeraction --downloadassets
$ echo The bird is the word, desu

I always forget the syntax for this, and how-to sites are even more of an awful mess of newsletter sign-up lightboxes, JavaScript, downloaded fonts, notification requests, chatbot popups, and other hot garbage. The irony isn’t lost on me that this conclusion was also entirely pointless!
