Crystalfetch2.2.0

Crystalfetch turns UUPDump-based Windows 11 releases into installer ISO images through a macOS interface, giving Mac users a way to prepare Windows installation media. The resulting ISO can be used with UTM virtual machines as well as other virtual machine solutions, supporting different virtualization setups.

The application combines UUPDump APIs with converter scripts to assemble the Windows files, then uses esd2iso by Technogeezer for the ESD-to-ISO conversion. This sets it apart from a generic ISO writer because it creates the Windows image from UUPDump content rather than simply recording an existing image.

Crystalfetch is aimed at Mac users setting up Windows 11 in a virtual machine, particularly with UTM or another VM platform. It runs on macOS 12 Monterey or later, supports Intel and Apple Silicon Macs, and belongs to the System Tools category. Version 2.2.0 is distributed as freeware.

Building the project from source requires initializing its Git submodules with git submodule update --init and using Xcode to build and run it. A paid Apple Developer license permits code-signing details to be supplied through CodeSigning.xcconfig; without one, each build target must have Disable Library Validation enabled under Signing & Capabilities.
