You may recall my post from last year detailing the steps on how to create a bootable USB drive for macOS Mojave. Thank goodness Apple still allows for end users to do this; there’s something about possessing physical media that makes things so much easier from a technical perspective.
Despite the fact that you will now need to use a USB drive with a minimum capacity of 16GB as opposed an 8GB one that was standard with past versions, the steps haven’t changed much…check out AppleInsider’s summary on how to perform this task here.
