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.
Download the latest version here.
or install it via cask: brew install --cask keepingyouawake.
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.
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.
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.
KeepingYouAwake is inspired by 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 command line tool under the hood.
