@@ -101,6 +101,7 @@ Docs: https://docs.openclaw.ai
 - Gateway/Linux: include fnm `aliases/default/bin` in generated service PATHs and let doctor accept either modern fnm aliases or the legacy `current/bin` symlink, avoiding false PATH repair prompts. Fixes #68169. Thanks @richard-scott.
 - Installer/Linux: run apt installs with noninteractive dpkg and needrestart settings so fresh Ubuntu 24.04 `curl | bash` installs do not hang while installing Node.js, Git, or build tools. Fixes #41146. Thanks @iht76, @alexcarv318, @cs3gallery, @firofame, and @cgdusek.
 - Providers/Bedrock: defer the AWS SDK import until Bedrock discovery actually runs so plugin registration and setup stay lightweight on cold start. Fixes #71690. Thanks @jarvis-ai-gregmoser.
+- Installer/macOS: stop immediately when Homebrew `node@24` installation fails and avoid printing PATH advice for missing Homebrew Node installs. Fixes #70411. Thanks @1fanwang.
 - WhatsApp: remove ack reactions after a visible reply when `messages.removeAckAfterReply` is enabled, matching other reaction-capable channels. Fixes #26183. Thanks @MrUnforsaken.
 - Providers/Z.AI: map OpenClaw thinking controls to Z.AI's `thinking` payload and add opt-in preserved thinking replay via `params.preserveThinking`, so GLM 5.x can keep prior `reasoning_content` when requested. Fixes #58680. Thanks @xuanmingguo.
 - Channels/status: keep read-only channel lists on manifest and package metadata by default, loading setup runtime only for explicit fallback callers. Thanks @shakkernerd.
