 # Production readiness roadmap
 
+## Native Apple Silicon support — 2026-10-23
+
+- [x] Build/install the normal Metal/CPU runtime and Tauri desktop on Apple M4,
+  verify bundled assets and native GPU query inference.
+- [x] Relocate the speech worker and shared libraries using `@loader_path`;
+  verify installed linkage and actual Whisper recognition on Metal.
+- [x] Verify native document/code search, media previews, timestamped audio/video
+  playback and artist metadata lookup; document the complete source installation.
+- [x] Verify native watcher lifecycle using canonical Mac paths (57 desktop tests pass).
+- [x] Exclude Mac system trees, mounted volumes and user Library app state from
+  automatic indexing, preserving personal document roots.
+
+Evidence and limits: [Mac runtime](MACOS-RUNTIME.md). Homebrew FFmpeg remains a
+local dependency. Intel/universal builds, clean-machine redistributable media,
+Developer ID/notarization, hotkey/tray checks and broad CPU/GPU quality parity
+remain open; these native M4 checks do not complete every platform release gate.
