Features

  • Native and lightweight

    4.7MB. Built with SwiftUI, runs on Apple Silicon and Intel. No Electron, no bundled browser engine, no dependencies.

  • Safe by design

    Your startup disk and internal drives are always hidden. Clear labels help you identify the correct USB drive. Writes are verified every time.

  • No telemetry

    No analytics, no crash reporters, no accounts, and no third-party packages that could add them. Transparent and open-source.

How it works

  1. Choose image

    Pick any .iso or .img, like Ubuntu, Fedora, Debian, or Raspberry Pi OS.

  2. Choose drive

    Only USB drives and SD cards are listed by default.

  3. Write & verify

    Written, checked byte by byte, then ejected.

Requirements

  • macOS 14 or later.
  • .iso and .img files only.
  • Windows ISOs are not supported, and the app warns when an ISO probably won’t boot from USB.
