Much like users that work remotely or in hybrid environments have grown accustomed to bringing the accessories they need with them that allow them to be their most productive, a small tool that many mobile users carry with them already and about twenty minutes of time is all that’s necessary to create your very own USB installer drive with the latest version of macOS on it.
