MAC OS USB CREATOR FOR WINDOWS INSTALL
If you would like to create an install drive for a macOS version other than Catalina, just tweak the paths above to refer to Mojave or High Sierra instead. Give it some time, and your volume will soon be loaded up with not just the macOS installer but also an external recovery partition that may come in handy if your hard drive dies and you're away from an Internet connection. The command will erase the disk and copy the install files over. Sudo /Applications/Install\ macOS\ Catalina.app/Contents/Resources/createinstallmedia -volume /Volumes/Untitled

Assuming that you have the macOS Catalina installer in your Applications folder and you have a Mac OS Extended (Journaled)-formatted USB drive (which is to say, HFS+ and notAPFS) named "Untitled" mounted on the system, you can create a Catalina install drive using the following command. The Install Disk Creator is just a wrapper for the terminal command to create macOS install disks, so if you’re comfortable formatting your USB drive yourself and opening a Terminal window, it’s almost as easy to do it this way. This should only take a few minutes on a USB 3.0 flash drive in a modern Mac, though using USB 2.0 will slow things down. A progress bar across the bottom of the app will tell you how far you have to go, and a pop-up notification will let you know when the process is done. Once you're ready to go, click "Create Installer" and wait. You can navigate to a different installer if you want, and you can also pick from all the storage devices and volumes currently connected to your Mac through the drop-down menu at the top of the window. Install Disk Creator will automatically detect macOS installers on your drive and suggest one for you, displaying its icon along with its path.

Apple rolls support for newer hardware into new macOS point releases as they come out, so this will help keep your install drive as universal and versatile as possible. If you want to use this USB installer with newer Macs as they are released, you'll want to periodically re-download new Catalina installers and make new install drives. There are other apps out there that do this, but this one is quick and simple. If you want a GUI, take a look at Ben Slaney's Install Disk Creator from MacDaddy.The installer will delete itself when you install the operating system, but it can be re-downloaded if necessary.
