Caffeine for Mac: Prevent Sleep and Screensavers
A small utility application for macOS that keeps your Mac awake during presentations, uploads/downloads, or video calls, preventing sleep, screen dimming, and screensaver activation.
What is Caffeine for Mac?
Caffeine for Mac is a free, open source application that helps prevent your Mac from automatically going to sleep, dimming the screen, or starting up the screensaver during periods of inactivity. It's a small but useful utility that sits in your menu bar and allows you to temporarily override your energy saving settings with a single click.
When launched, Caffeine will display an icon in your menu bar that visually indicates whether or not it is currently preventing sleep. You can click the icon to toggle Caffeine on or off. This provides a quick, convenient way to keep your Mac awake without having to adjust system preferences. For example, Caffeine is helpful for keeping presentations running smoothly, preventing screensavers from interrupting long downloads or uploads, or stopping video calls from ending prematurely if you step away for a minute.
Since Caffeine is very lightweight software with a simple on/off function, it uses minimal system resources. It's completely customizable as well - you can set a custom icon, choose how long to keep the Mac awake when activated, or even use keyboard shortcuts for fast access instead of clicking the menu bar icon.
As a free, open source application, Caffeine is a popular choice recommended by many Mac users for selectively disabling sleep or screensaver modes as needed. If you find yourself needing to keep your Mac awake more often, give Caffeine a try.
