HIARCS Chess Explorer Pro
HIARCS Chess Explorer Pro is a comprehensive chess database, analysis and game-playing application for macOS. It combines a powerful PGN chess database with the HIARCS chess engine (currently version 15.4, one of the strongest available), supporting analysis from beginner level through World Championship strength and beyond. The app is designed for players of all levels—from casual enthusiasts to professional grandmasters—offering features like game analysis, opening preparation, position search, endgame tablebases, opening books with statistics, engine matches, and the ability to connect to Millennium physical chess boards. It supports multiple languages and integrates UCI-compatible engines.
AI Recommendation
1 suggestionHIARCS Chess Explorer Pro ships as a native Universal Binary for Apple Silicon. The vendor's own download page confirms that version 1.5.2 (released April 2026) and all recent builds run natively on M-series Macs—not under Rosetta 2, but as genuine arm64 builds. Simply download the latest installer from hiarcs.com and run it; the app will automatically update your existing installation. If you are currently running an older Intel-only version under Rosetta, updating to the latest build will give you noticeably faster performance, lower power consumption, and full native macOS integration. No beta channel or special opt-in is required—the main download serves the native build to Apple Silicon Macs.
