What you get

Keep your Mac working even when you step away.

You can leave your Mac downloading a file or running an app without sleep interrupting it. Start a keep-awake session from the menu bar, then let it run indefinitely, for a set duration, or until a particular time. You can also tie the session to a download or a specific app, rather than remembering to turn it off yourself.

You decide whether your display stays on too. That means you can keep your Mac awake with the screen asleep, or keep the screen visible when you need to watch it. You can also choose whether the screen saver and screen locking are allowed during a session.

If your routine repeats, you can have sessions start automatically when you connect a display, join a particular Wi-Fi network, or plug in power. You can set sessions to end when your battery runs low. The app is free, with no ads, paid upgrades, or tracking.

  • Leave downloads running

    You can keep your Mac awake while a file downloads, without periodically touching the keyboard.

  • Let your screen rest

Skip it if
