The primary utility of this DMG file is to bypass the Catch-22 of Hackintoshing: creating a macOS bootable drive usually requires a Mac. For a user operating solely on Windows, this DMG provides a pre-configured environment. By writing this image to a USB drive using software like Win32 Disk Imager , a Windows user can instantly transform a generic flash drive into a bootable macOS Recovery or Installer drive. This allows the computer to boot into a recognizable macOS interface, format the internal hard drive to APFS (Apple File System), and launch the installation of the operating system.
This "Trojan horse" approach successfully bypasses the operating system barrier, bringing the powerful Checkra1n jailbreak to millions of Windows users in an accessible, portable way.

Since checkra1n was originally built for macOS, Ra1nUSB acts as a pre-configured "live" environment—essentially a portable macOS installer—that allows you to boot your PC into a environment where the jailbreak can run.
