About KeepingYouAwake

KeepingYouAwake is a menu bar utility for macOS 10.13 and newer that prevents a Mac from entering sleep mode for a predefined duration or while activated. It functions as a wrapper around Apple's caffeinate command line utility included with macOS.

It can be installed by download or with a Homebrew cask command. It does not prevent sleep on a MacBook with a closed lid, and older macOS versions require older app releases.
