KeepingYouAwake is a small menu bar utility for macOS (Version 10.12 and newer) that can prevent your Mac from entering sleep mode for a predefined duration or as long as it is activated.


Download the latest version here.

or install it via cask: brew install --cask keepingyouawake.

How does it work?

The app is a small wrapper around Apple's caffeinate command line utility. All current versions of macOS ship with this tool by default. You can read the manual page here. On a MacBook this only works as long as the lid is open.

Is this dangerous?

This utility will not harm your Mac because it is based on an official command line tool by Apple. BUT I cannot guarantee anything, so use this tool AT YOUR OWN RISK.

Inspired by Caffeine

KeepingYouAwake is inspired by Caffeine from Lighthead Software. I used it for many years, but sadly it hasn't been updated in a while. Eventually in 2014 I decided to build a replacement for myself that was optimized for macOS Yosemite and used the caffeinate command line tool under the hood.

Still using macOS Yosemite?

Version 1.5.2 is the latest release that supports macOS Yosemite and El Capitan.

Help Wanted!

Do you want to improve the app or add useful features? Please go ahead and create pull requests. I'm thankful for any help.

Building the Source Code

KeepingYouAwake uses Sparkle's ui-separation-and-xpc branch to deliver updates. You can build and sign Sparkle with make Vendor. To build a release version of the app just run make dist.
