Real movement
Moves the mouse at the operating-system level, not a fake cursor. Resets the inactivity timer for every app at once.

More than “keep awake”
Classic Mac tools like Caffeine, Amphetamine or KeepingYouAwake stop the screen sleeping, but they don't reset idle time, so Teams or Slack can still mark you away. KeepOnDuty generates real movement and truly keeps your presence active.

FAQ
Frequently asked questions
How do I move the mouse automatically on Mac?
Download KeepOnDuty for macOS, grant it Accessibility permission the first time and press Start. It moves the mouse at the interval you choose.
Why does KeepOnDuty ask for Accessibility permission?
macOS requires that permission for an app to move the cursor. It's a system requirement; KeepOnDuty uses it for nothing else and sends no data.
Does it work on Apple Silicon (M1/M2/M3)?
Yes, it works on Apple Silicon and Intel Macs.
Is it better than Caffeine or Amphetamine?
For “don't sleep” they're fine; for “don't appear away” KeepOnDuty goes further because it actually moves the mouse and resets inactivity, which Caffeine doesn't.
