This app isn't maintained, and likely doesn't even work on recent versions of macOS. You should use Amphetamine instead, it's really good.
Caffeinator is a menu bar utility based off of Lighthead Software's Caffeine and Marcel Dierkes' KeepingYouAwake. It allows you to prevent your Mac from going to sleep and your screen from turning off.
I wrote this clone because Caffeine hasn't been updated in a long time and I wanted to tweak some behaviors of KeepingYouAwake. Also, I'm an iOS developer and I wanted to try my hand at the other side (this is my first OS X app). Additionally, this app is written completely in Swift.
You can download the compiled app here
or you can build the code yourself using Xcode 7.
- OS X 10.10 Yosemite or later
- Xcode 7 or later (if you want to build the source)
Although this application is essentially just a wrapper around Apple's caffeinate utility, I make no promises about the safety of this application. Thus, use this application at your own risk.
Lighthead Software for the original application, Caffeine.
Marcel Dierkes for the open-source Objective-C clone, KeepingYouAwake.
