Don't Idle

The context

Step away for a few minutes and your Mac dims while your Slack or Teams dot turns yellow. Don't Idle reads real input-idle time and, past a threshold you choose, posts a tiny mouse movement that returns in place — enough to read as active everywhere. It runs only during the hours and weekdays you set, and uses an adaptive single-timer engine instead of busy polling, so it barely touches the battery.

Decisions that were mine

1. 01Real input events, not a fake cursor warp

   The nudge posts a genuine CGEvent mouse move to the HID tap, which resets macOS idle time and keeps chat presence active. That requires Accessibility, so onboarding refuses to finish until the permission is actually granted.

2. 02Battery-first: adaptive timer, no polling

   Instead of checking every second, the engine schedules a single wake-up at the next decision point and sleeps completely when paused or outside the active window — with timer leeway so the CPU can coalesce wake-ups.

3. 03Shipped like a real product

   Developer ID signing plus Apple notarization (stapled, hardened runtime, universal binary) so it opens with no Gatekeeper warning — and a custom self-update flow that downloads, swaps the app bundle and relaunches, validated end to end.
