NoNap — Keep your Mac awake — exactly when it needs to be.

How it works

Two ways to keep your Mac awake.

NoNap preventing idle sleep with a visible countdown timer

01

Prevent idle sleep

Choose Timed or No Limit. When a timer ends, your Mac returns to normal sleep behavior on its own.

NoNap keeping the display awake independently

02

Keep Display On

Keep the screen lit for the current wake session. It follows the session and can be turned off independently at any time.

Features

Simple, focused, reliable.

  • Timed keep-awake

    Prevent idle sleep for a set duration — a 2-hour countdown by default, adjustable in 30-minute steps. Or switch to unlimited mode with no natural end.

  • Keep Display On

    Keep the display lit for the current wake session, and turn it off without ending the session.

  • Native menu bar app

    Lives entirely in the menu bar. No dock icon, no main window — just a single click to toggle. Built with SwiftUI and native macOS APIs.

Availability

Free on the Mac App Store.

No subscription, no trial, no catch.
