Many of us take sleep for granted. And the same goes for our Macs. Sleep Mode was first introduced on the Mac with MacOS X 10.4 and the PowerBook G4, back in October 2005. Sleep Mode is a low power mode that saves the contents of RAM to your Mac’s hard drive. In modern Macs, Sleep Mode will let it run certain tasks in the background.
Sleep Mode brings a lot of benefits. With it, you no longer need to shut your Mac off when it’s not in use. Your Mac will hibernate until you wake it up (usually with a keypress or a click of your input device). Sleep mode not only lets you pick up your work where you left off, it also conserves energy when your Mac is not in use. It’s ideal for portable devices (like MacBooks) since Sleep Mode helps conserve your battery’s charge.
But, as helpful as Sleep Mode is, there are times where you want your Mac to stay awake. Perhaps you are capturing a sizable download that needs to continue when you’re not in front of your Mac. Or maybe you’re running a Mac as a server that needs to be available 24/7. Or you are making a presentation on a Zoom call. Whatever your case may be, there are options to prevent your Mac from sleeping, dimming the display, or triggering a screensaver.
One of those options is a program called Caffeinated, the Anti-Sleep app, by Yugen GmbH. Currently at version 2.0.2, Caffeinated has one job: it keeps your Mac from falling asleep. (This program should not be confused with Caffeine, which offers similar functionality. )
Caffeinated, which has an aptly chosen coffee cup as its icon, lives in your Mac’s toolbar. You can specify the duration for your Mac’s insomnia (from 15 minutes to Infinite) with a single click.
You can also instruct Caffeinated to set your Mac’s display to sleep to conserve energy. Your Mac will continue to work behind the scenes, uninterrupted.
A global keyboard shortcut can be assigned to activate or deactivate Caffeinated, or simply activate it with a left or right click via its settings. (I use my StreamDeck to toggle Caffeinated’s behavior.)
As a menu bar item, Caffeinated lets you assign a custom color so you can easily find it. This option makes it really easy for users to find Caffeinated amidst the slew of menu bar items often found when running macOS.
Caffeinated does what it says on the tin. It’s a Mac app through and through, sporting a modern design that fits right in with macOS Ventura. Its simplicity is what I like most about Caffeinated. To quote an old television slogan: “Set it and forget it.” I also like that the developer is actively updating and maintaining the program, and receptive to adding new features for future versions.
And speaking of features, one feature I would like to see in an upcoming version of Caffeinated is app-specific triggers. If, for example, I have Apple Music running, I would like Caffeinated to activate to keep my Mac from falling asleep. Support for Apple Shortcuts would also be really useful. And, on a nerdy note, I would like Caffeinated to show me simple statistics, like an ongoing tally of how many months, days, and years I’ve kept my Mac awake when Caffeinated is activated.
Caffeinated is built entirely in SwiftUI and works great on Intel Macs and is also optimized for Apple Silicon. Caffeinated costs $3.99US on the Mac App Store.
