Lungo prevents your Mac from falling asleep and your screen from dimming.

This can be useful when:
- Doing a presentation at work
- Watching YouTube videos in non-fullscreen mode
- Cooking and having the recipe open on your computer
- Reading a long article without scrolling
- Using the screen to view live stats
- Monitoring progress on a long-running task

- Right-click or Option-click the menu bar icon to quickly activate.
- Choose to activate with left-click instead in the Preferences.
- Choose to activate at launch in the Preferences.
- Set the default duration in the Preferences, which is used when Lungo is activated by clicking the menu bar icon.

Important: Lungo will not prevent your Mac from sleeping if you close the lid. This is a Mac App Store limitation.

What's New

Version 1.3.0

- Added a "Default Duration" preference, which lets you set the duration used when Lungo is activated by clicking the menu bar icon. This was previously hard-coded to "Indefinitely".
- Added a welcome screen that is shown on the first launch.
- Fixed the menu bar icon not being highlighted on some machines on High Sierra.
- Fixed negative time remaining being shown after computer sleep.

Display won’t sleep if lungo is active


I have set my displays to turn off after 10 minutes in Energy Saver. If I manually activate the screensaver and don’t deactivate Lungo then my displays never turn off. I’ve used Caffeine in the past and this was never an issue. I had reached out to Lungo Support over a month ago but never received a response.

Developer Response

I seemed to have missed your email before. Sorry about that. This is not a bug though. The current behavior is in the app description: "[..] and your screen from dimming.". Lungo keeps your computer and screen awake. However, I plan to add support for only keeping your computer awake, not the screen.

Solid keep-awake app


Sindre has once again contributed a useful tool to the community. If you need something to do what this says it does - it does it well!

Does the same as Caffeine, but nicer :)

TK Running

At the moment it looks to be on feature parity with Caffeine, but nice little touches such as retina icon and small animations make it look a bit nicer :)
