KeepingYouAwake

KeepingYouAwake is a small menu bar utility for macOS Yosemite (Version 10.10) and newer that can prevent your Mac from entering sleep mode for a predefined duration or as long as it is activated.

Installation

Download the latest version here.

or install it via cask: brew cask install keepingyouawake.

Screenshots

Why does this project exist, Caffeine.app works perfectly fine?

Caffeine from Lighthead Software is a great utility and I used it for many years, but it hasn't been updated in a while. Its icons are not Retina-compatible and do not look nice in the dark themed menu bar.

How do you prevent my Mac from sleeping?

This utility is just a small wrapper around Apple's caffeinate command line utilty. Any modern Mac ships this tool by default. You can read the manpage here.

Is this dangerous?

Just to make it clear: this utility shouldn't harm your Mac because it is using an official command line tool from Apple, BUT I cannot guarantee anything, so use this tool AT YOUR OWN RISK.

Help Wanted!
