Special Offer: FREE for a limited time!
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 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
◦ 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 in the past, but macOS no longer allows apps 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.
Several small feature and stability improvements, including:
• You can now right-click the Coffee Buzz menu bar item to switch between modes.
• You can move the menu bar item wherever you want—it's not stuck on the end anymore! (macOS Sierra only)
• If you don't care for the default mode names, you can now choose plainer ones.
• The crash related to the Preferences window has been fixed. Sorry about that!
• Various bug fixes.
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!
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!
Solid and Dependable
This program works exactly as advertised and I use it every day at work to keep my computer from sleeping when I don’t want it to. The timers and the ability to choose between “buzz” and “doze” modes set this app apart from other sleep prevent apps.
With Family Sharing set up, up to six family members can use this app.
