Roman Loyola shares a tip for Apple users looking to upgrade: Creating a macOS Catalina bootable drive.
An external drive that you can use as an installer for macOS Catalina is a handy thing to have. If you have multple Macs to upgrade, it’s a lot more efficient to plug in the USB installer drive and run the installer than to log into the App Store, download the 6.5GB OS installer, and then run it.

It is amazing how people complicate things including third-party applications like “Install Disk Creator”, “DiskMaker X” or similar; and even Terminal commands. It is much easier than that. Just 1-2-3:
1. Download the macOS installer and open it.
2. Select the desired destination disk and install.
3. Boot from such disk.
That is! No Terminal commands needed. No third-party applications needed either. The Mac way!
