StayUp 1.1.2

Quiet UX patch. Update prompts now surface on app launch for opted-in users and come to the front (instead of opening behind your other windows). StayUp briefly shows a Dock icon while the prompt is up — the only way a menu-bar app can raise a window over the app you're using — then tucks it away. Still opt-in, still no network before consent.

StayUp 1.1.1

Maintenance patch — no new features, no breaking changes.

Security — the root Helper now verifies the connecting client's uid (getpeereid) and honours sleep-control commands only from a real interactive user or root, rejecting other local processes. Closes the unauthenticated-toggle exposure on the world-traversable /var/run socket. The normal engage path is unaffected.

Changed — ~/.stayup/status.json (the bundled dashboard's diagnostic) now refreshes at most every 5s on the idle Auto tick instead of every second, dropping a per-second disk write and ioreg spawn while Auto holds the Mac awake. On-screen UI unchanged.

StayUp 1.1 — Agent-aware Auto mode

Duck is better at knowing when work is real.

StayUp 1.1 makes Auto mode agent-aware: selected local work can keep the Mac awake, then Duck stands down after your grace period when that work stops.

What's new

• Claude, Codex, and Cursor can report working vs waiting through StayUp-managed local hooks.
• Cursor is now a bundled Activity Source.
• Auto mode now releases after your selected grace period: 5, 15, 30, 60, or 180 minutes.
• The Activity Sources menu shows running vs waiting sessions, heartbeat age, tool counts, and local token totals where transcripts are readable.
• Claude recap/compaction no longer makes an idle session look active forever.
• Delete and Clean Up Hooks are safer: StayUp removes only StayUp-owned hook entries and leaves your other hooks/settings alone.
• Turning on automatic update checks now starts one immediate background check, so an available signed update can appear right away.

StayUp 1.0

StayUp 1.0

First public release.

StayUp is a free Apple Silicon Mac menu-bar Duck that keeps local work alive
when macOS would rather sleep. It is built for long-running local AI agents,
model servers, renders, downloads, and local server work.

Highlights

• Manual On / Off. Click the menu-bar Duck to keep the Mac awake now, then
  click again to let it sleep normally.
• Auto mode. Trusted local Activity Sources can prove work is still alive.
  StayUp keeps the Mac awake while selected sources are active, waits through a
  grace period when they go quiet, then stands down.
• Battery + lid-closed Helper path. The hard case uses a readable root
  helper daemon registered through SMAppService to run
  pmset disablesleep on/off. No sudoers installer.
• Layered sleep prevention. StayUp combines Apple's caffeinate, IOKit
  assertions, a closed-lid assertion, optional virtual display support for
  remote GUI workflows, and the Helper path.
• Virtual display for remote GUI availability. If no real external monitor
  exists, StayUp can create a small virtual display so screen-sharing style
  tools have a display-shaped surface. This is not the hard sleep guarantee;
  the Helper owns that.
• Don't Die. StayUp can disengage before low battery so the Mac is not kept
  awake forever.
• Walking Duck. On Apple Silicon MacBooks with the right motion hardware,
  the menu-bar Duck walks when you carry the Mac. The sensor is local-only and
  only active while StayUp is engaged.
• First-launch setup. The welcome window surfaces Launch at Login, Helper
  setup, and optional update checks.
• Settings. General, Advanced, Walk, Look, and About tabs keep the controls
  compact.
• Sparkle updates. Signed update checks are opt-in or manually requested.
• No telemetry. No analytics, accounts, crash reporting, or normal-operation
  network calls.

Notes

• Direct-distribution only. The hard-case Helper and private virtual display
  API do not fit the Mac App Store sandbox.
• The Helper is required for the battery + lid-closed promise.
• Do not keep a closed MacBook running in a bag, drawer, or other poorly
  ventilated place.
• Code is MIT licensed. The StayUp name and Duck artwork are reserved.
