Crystalfetch
UI for creating Windows installer ISO from UUPDump
CrystalFetch is a macOS application that builds Windows 11 installer ISO images from the UUPDump service. It provides a graphical interface for downloading the necessary UUP files, converting them with the bundled esd2iso utility, and producing a ready‑to‑use ISO that can be mounted or supplied to virtual machines. The tool is designed to work with UTM and other VM platforms that support Windows 11 installation.
The software targets macOS users who need to create Windows 11 ISOs without using command‑line tools. It is suitable for developers, testers, and anyone running Windows 11 in a virtual environment on a Mac. A valid Windows 11 license is required, and the project is not affiliated with Microsoft.
CrystalFetch relies on the UUPDump APIs and the esd2iso conversion script, and it can be built from source with Xcode. The repository includes build instructions, and the project is listed as stable for macOS.
