So, what is required for making a bootable USB drive?

• 1 USB Drive (16GB or larger) – You can get these from Amazon.com.
• You’ll need to download the MacOS Mojave installation app and put it in the /Applications/ folder (Direct Link)
•  Conform that the ‘Install macOS Mojave.app’ is in the /Applications/ folder.
•  Connect the USB Drive to the Mac.  You may need to format (prep) the drive to save files onto it.
•  Launch the Terminal App located in /Applications/Utilities folder.
• At the Terminal window, type the below command:

sudo /Applications/Install\ macOS\ Mojave.app/Contents/Resources/createinstallmedia --volume /Volumes/UNTITLED --nointeraction && say Mojave Drive Created

• Press [Return] and enter the Administrator’s password (as required by sudo).

The making of the disk can take a while, depending on the speed of your Mac.

That’s it.
