## What it is
WinDiskWriter is a native macOS application for creating bootable Windows USB installers that support both UEFI and Legacy BIOS boot modes. It can also patch Windows 11 installers to bypass TPM, Secure Boot, and minimum RAM requirements.

## Use cases
- create a bootable Windows 11 USB installer from macOS
- bypass TPM and Secure Boot checks when installing Windows 11
- make a Windows USB drive that boots on both UEFI and Legacy BIOS systems
- install Windows on an Intel Mac or a virtual machine from a USB stick
- write a Windows ISO to a USB drive without using Boot Camp Assistant

## When to choose
- you are on macOS and need to create a Windows installation USB
- you want to install Windows 11 on hardware lacking TPM or Secure Boot
- you need a single USB drive that works in both UEFI and Legacy BIOS modes
- you want a free, open-source GUI alternative to Boot Camp or UNetbootin on Mac

## When to avoid
- you are on Linux or Windows and need to create the installer there
- you need to create bootable USBs for non-Windows operating systems
- you require command-line-only automation rather than a GUI app
- your Mac runs Apple Silicon only and lacks Intel Mac compatibility for testing
