Method 1: Create macOS Catalina Bootable USB on Windows 10 via DMG Editor

DMG Editor, a popular app developed by UUByte, is a multi-functional and cross-platform image burning tool that works on Windows, Linux and macOS. It supports creating bootable USB from popular image files, including dmg, iso, zip, img.
