This comprehensive guide will walk you through the entire process, from downloading the macOS installer to formatting your USB drive and creating a bootable image.

Why Create a Bootable USB Installer on Windows?

While macOS is primarily designed for Apple devices, there are situations where you might need to create a bootable USB installer on a Windows machine. This could be for:
