Funny you mentioning „caffeine“ [1]as this is also an app for macOS which solves the same purpose as the one posted. But this one is not in the App Store. I just had a look and next to amphetamine we have taurine, theine and caffeinated and a few more that use some form of coffee / a substance that keeps one awake. The „Prevent Sleep“ app is the only one which clearly states what it is for :) [1] https://intelliscapesolutions.com/apps/caffeine
