+# NemoClaw Mac Installer Preview
+
+Experimental macOS SwiftUI shell for the opt-in Mac Installer Preview path.
+
+The app calls the app-facing CLI APIs:
+
+- `nemoclaw native-installer mac assess --json`
+- `nemoclaw native-installer mac install --config <json> --json-progress`
+- `nemoclaw native-installer mac launch --agent <openclaw|hermes> --json`
+- `nemoclaw diagnostics export --output <path>`
+
+Set `NEMOCLAW_MAC_INSTALLER_CLI` to point at a bundled or local `nemoclaw` binary during development.
+Release builds should use the payload assembled by `scripts/native-installers/macos/build-preview.sh`.
