 ### Fixes
 
 - Agents/models: forward model `maxTokens` as the default output-token limit for OpenAI-compatible Responses and Completions transports when no runtime override is provided, preventing provider defaults from silently truncating larger outputs. (#76645) Thanks @joeyfrasier.
+- macOS CLI/onboarding: honor sensitive wizard text steps in `openclaw-mac wizard` with termios no-echo input, suppressing saved credential previews while preserving long API keys and gateway tokens. Fixes #76698. Thanks @anurag-bg-neu and @sallyom.
 - Control UI/Skills: fix skill detail modal silently failing to open in all browsers by deferring `showModal()` until the dialog element is connected to the DOM; the Lit `ref` callback fired before connection causing a `DOMException: HTMLDialogElement.showModal: Dialog element is not connected` on every skill click. Thanks @nickmopen.
 - Gateway/update: run `doctor --non-interactive --fix` after Control UI global package updates before reporting success, so legacy config is migrated before the gateway restart. Thanks @stevenchouai.
 - Gateway/cron: stop a lazy cron startup that loses a hot-reload race, preventing the old cron service from starting after reload has already replaced cron state.
