Coffee Buzz is the easiest and safest display-sleep preventer available, with simple operation and exclusive Safety Auto-Shutoff feature. Keeping your Mac awake (and letting it sleep again) is now as simple as a click!
• Flexible user interface that works as both a window and as a menu bar status item (or both at once)
• Three easy-to-use settings:
◦ Buzz mode: Keeps the display awake no matter what
◦ Doze mode: Lets the display sleep but keeps the computer itself awake
◦ Off: Allows you to disable the caffeinated effect without having to quit Coffee Buzz
• Timer that can be controlled from both the window and the status bar
• Configurable automatic mode switching when the power adapter on a portable Mac is connected or disconnected or the battery gets low
• Exclusive Safety Auto-Shutoff feature designed to reduce the chance of accidental display damage or burn-in. While not intended to be a substitute for responsibility and careful use, Safety Auto-Shutoff can keep a mistake from turning into an expensive headache.
Note: This app cannot prevent your Mac from sleeping if you use the Sleep menu command or close the screen on a portable Mac. This used to be possible years ago, but macOS no longer allows applications of any type to block the user's direct commands to enter sleep.
Comments, questions, and feedback are always welcome. Please visit Coffee Buzz Support for more information.
• This version fixes several bugs, including one that could cause unnecessarily high CPU usage under certain circumstances.
• Power rules, if set, are now applied at the time Coffee Buzz is launched.
Ratings and Reviews
Essential when doing lectures with slide shows
Coffee Buzz is definitely one of those apps where, once I started using it, I can’t live without it. I use my Mac with a projector all the time when teaching, and with Coffee Buzz, I never have to worry about my display falling asleep when I’m in the middle of referencing an image on the screen. It’s simple, easy to use, and brilliant!
easy to use, just enough settings
I love that it is smart enough to no drain my batter when it gets below a certain percentage and power is not connected. That’s what makes it better than other similar apps.
When you’re in the middle of a project, you can’t stop and worry about your display turning off… I love this app. I have it on all my Mac’s. If you need something to help not distract you from your display turning off, get this app!
With Family Sharing set up, up to six family members can use this app.
