System requirements

  • macOS: a recent macOS on Intel or Apple Silicon. The build is self-contained — no separate .NET install.
  • Windows: 64-bit Windows 10 or 11. Self-contained — no separate .NET install.
  • Network: none required. The app runs fully offline; the only optional network use is a manual check for updates on GitHub.
