HIARCS Chess Explorer
HIARCS Chess Explorer is a chess database, analysis and game-playing software for macOS. It includes the World Chess Software Champion HIARCS engine with playing strengths ranging from beginner (750 Elo) to World Championship level (3100+ Elo) and human-like play at all levels. The application serves chess players of all abilities—from casual learners to grandmasters—offering features like game analysis, blunder detection, opening book preparation, instant position search, engine matches, Millennium eBoard integration, and access to large PGN databases with over 200,000 games. Users can analyse chess positions, play against the engine at customisable difficulty, and explore opening theory with built-in and online opening books.
AI Recommendation
1 suggestionThe latest version of HIARCS Chess Explorer (v1.14, released May 2026) explicitly supports both Intel and Apple Silicon Macs natively, so you already have access to the native build. The vendor's download page confirms the current version runs natively on M1, M2 and Pro chips without requiring Rosetta 2, meaning your app is already future-proof for macOS 28 (September 2028) when Rosetta is removed. If you are still running an older version of HIARCS Chess Explorer, download the latest installer from hiarcs.com/mac-chess-explorer-download.html—the installation process is straightforward and will preserve your databases and settings. No special steps or beta channels are needed; the standard installer serves the native Apple Silicon build to M-series Macs.
