--- summary: "Detect the Mac you most recently used and route node alerts there" read_when: - You want OpenClaw to identify the active Mac - You are debugging last-input activity or active-node selection - You want to understand node connection notification routing title: "Active computer presence" --- Active computer presence tells the Gateway which connected macOS node received the most recent physical mouse or keyboard input. OpenClaw uses that signal to mark one Mac as `active`, give the agent a stable active-node hint, and route node connection alerts to the computer where you are most likely present. This is separate from [system presence](/concepts/presence), which is the live roster of Gateway clients, and from durable `node.presence.alive` beacons, which record when a mobile node last woke without treating it as connected. ## Requirements - The OpenClaw macOS app is paired and connected in node mode. - **Accessibility** permission is granted to the signed OpenClaw app. - For connection alerts, **Notifications** permission is also granted and the Mac node exposes `system.notify`. Activity reporting is currently implemented by the native macOS node. iOS, Android, watchOS, and headless node hosts can report connection or background last-seen state, but they do not compete for the active-computer designation. ## Check the active computer 1. In the macOS app, open **Settings -> Permissions** and grant **Accessibility** in macOS System Settings. 2. Confirm the Mac node is connected: ```bash openclaw nodes status --connected ``` 3. Move the mouse or press a key on that Mac, then run: ```bash openclaw nodes status openclaw nodes describe --node ``` The freshest eligible Mac is marked `active`. Status output shows its last-input age; `describe` exposes `active`, `lastActiveAtMs`, and `presenceUpdatedAtMs`. Activity is intentionally coalesced, so the display may take up to about 15 seconds to reflect another input after a recent report. ## How activity becomes presence The macOS reporter samples the HID system idle clock every two seconds. It reports once when a node connection becomes ready, then reports newer physical activity no more than once every 15 seconds. While idle, it sends a keepalive every three minutes. Idle duration is capped at 30 days so a very old sample cannot drift forward and incorrectly become the newest computer. The Gateway accepts activity only when all of these are true: - the event belongs to the current authenticated connection for that node id; - the node has effective `accessibility: true` permission; - the payload contains a bounded integer `idleSeconds` value. The Gateway subtracts `idleSeconds` from its own observation time to derive `lastActiveAtMs`. It never trusts a node-supplied wall-clock timestamp. Among connected eligible Macs, the newest `lastActiveAtMs` wins; a tie uses the most recent presence update. Presence is process-local and connection-bound. Disconnecting the current session, replacing it with another session using the same node id, or revoking Accessibility clears that node's activity state and recomputes the active Mac. ## Privacy and model context OpenClaw sends idle duration, not input content. It does not send key values, mouse coordinates, application names, window titles, or raw input events. The macOS reporter reads the hardware HID state, so synthetic computer-control events do not make an automated Mac appear to be the computer you physically used. Continuous activity does not create model-facing system events. The dynamic runtime line contains only the authenticated node id: ```text active_node= ``` Exact timestamps and node-controlled display names stay out of the prompt to avoid prompt injection and cache churn. When the agent needs current details, the `nodes` tool can read `node.list` or `node.describe` instead. ## How connection alerts are routed After a node finishes its Gateway handshake, OpenClaw waits 750 milliseconds so the connecting Mac can submit its first activity sample. It then tries the connected notification-capable Mac with the freshest activity. - If primary delivery succeeds, no other Mac receives the alert. - If no active Mac is available or primary delivery fails, OpenClaw waits five seconds and tries every remaining connected Mac that exposes `system.notify`. - A reconnect alert for the same node is suppressed for five minutes after an actual delivery attempt, preventing reconnect flapping from producing a notification storm. Alerts are bound to exact node connections. A disconnected or replaced source session cannot complete an old scheduled alert, and a replacement destination connection can still participate in fallback delivery. ## Troubleshooting | Symptom | Check | | ----------------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | No row is marked `active` | Confirm a native macOS node is connected and `openclaw nodes describe --node ` shows `permissions.accessibility: true`. | | The wrong Mac remains active | Use that Mac physically, wait for the coalescing window, then rerun `openclaw nodes status`. Synthetic computer-control actions do not count. | | Last-input data disappears | Check whether the Mac disconnected, its node session was replaced, or Accessibility was revoked. Each condition intentionally clears activity. | | The alert appears on several Macs | Primary delivery was unavailable or failed, so the delayed fallback ran. Verify that the active Mac is connected, allows notifications, and exposes `system.notify`. | | The agent does not mention the active Mac | Start a new turn after activity changes. The runtime hint is stable and compact; use the `nodes` tool for exact current metadata. | For TCC recovery, see [macOS permissions](/platforms/mac/permissions).
