Highball

Highball is a native macOS app and CLI for running Windows games on Apple Silicon. It assembles Wine engines from pinned upstream builds, sets up bottles, and supports renderer overlays for WineD3D, DXMT, D3DMetal, and DXVK; it can install Steam, connect an Epic library through Legendary, and switch renderers per bottle or launch.

Its compatibility database records verified runs, per-game renderer verdicts, community reports, machine-derived predictions, provenance, and kernel-anti-cheat blocklist entries. Declarative JSON recipes describe installer, registry, Winetricks, synchronization, renderer, version-pinning, and note steps applied to bottles, while the CLI can submit game results to the open database.

Highball requires Apple Silicon and macOS 14 or later. The app and CLI are licensed under GPL-3.0, while the recipes and compatibility database are CC0; D3DMetal is downloaded separately after acceptance of Apple's Game Porting Toolkit license. The project documents limitations with several Chromium-based launchers, Rockstar, Ubisoft Connect, GOG Galaxy, Battle.net, and the EA app.
