# KeepingYouAwake KeepingYouAwake is a small menu bar utility for macOS *(Version 10.13 and newer)* that can prevent your Mac from entering sleep mode for a predefined duration or as long as it is activated. https://keepingyouawake.app/ ## Installation **[Download the latest version here.](https://github.com/newmarcel/KeepingYouAwake/releases/latest)** or install it via [cask](http://caskroom.github.io/): `brew install --cask keepingyouawake`. <img src="./Extras/[email protected]" width="500" /> ## 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](https://web.archive.org/web/20140604153141/https://developer.apple.com/library/mac/documentation/Darwin/Reference/ManPages/man8/caffeinate.8.html). ### Does it work on a MacBook with a closed lid? No. Because of _(sensible)_ macOS limitations and out of thermal considerations, KeepingYouAwake will only prevent sleep on desktop Macs and portable Macs with an open lid. ## 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](https://web.archive.org/web/20240625031548/https://www.lightheadsw.com/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`](https://web.archive.org/web/20140604153141/https://developer.apple.com/library/mac/documentation/Darwin/Reference/ManPages/man8/caffeinate.8.html) command line tool under the hood. ## Still using old macOS versions? - [Version 1.6.2](https://github.com/newmarcel/KeepingYouAwake/releases/tag/1.6.2) is the last release that supports macOS Sierra (10.12) - [Version 1.5.2](https://github.com/newmarcel/KeepingYouAwake/releases/tag/1.5.2) is the last release that supports macOS Yosemite (10.10) and El Capitan (10.11) ## Contribution Guidelines If you plan to contribute to the project, I recommend taking a look at the [Contribution Guidelines](./CONTRIBUTING.md).
