KeepingYouAwake is a small menu bar utility for OS X Yosemite and above that can be activated to prevent your Mac from going into sleep.
You can toggle the state directly from your menu bar.
Download the latest version here.
or install it via cask: brew cask install keepingyouawake.
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 Yosemite's dark menubar mode.
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.
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.
Do you want to improve the app or add any useful features? Please go ahead and create pull requests. I'm thankful for any help.
KeepingYouAwake uses Carthage as dependency manager. You can install Carthage with Homebrew. Type brew update && brew install carthage and call carthage bootstrap in the KeepingYouAwake source code folder to download and build all dependencies.
This is my first Mac application in a long while. I am an iOS developer and don't know the AppKit APIs very well, so please bear with me.
