Idler

Keep your Mac awake with one click.

Sleep allowed
Sleep prevention active

Corporate-managed Macs often enforce aggressive sleep policies you can't override. Your screen locks, Slack goes "Away", colleagues think you disappeared — even though you just got coffee while a build runs.

Idler sits in the menu bar. Click once — it prevents system and display sleep via IOKit assertions and simulates user activity every 30 seconds. Click again to allow sleep normally.

Rewrite of the original Go version in native Swift.
