Prevent your Mac from falling asleep, dimming your screen or starting the screensaver. Theine keeps macOS awake just like caffeine does with you.

• It just works
Caffeinate your Mac through a simple click on its menubar icon or even better: define a custom global hot key. It is fast, lightweight and optimized for macOS 10.15 Catalina.

• Always on time
The timer function allows you to control exactly how long Theine should be activated. You can also set a custom default duration or choose to caffeinate your Mac infinitely.

• Less but better
Theine looks brilliant in light and dark mode. It is designed for modern retina displays and perfectly fits to macOS accent colors. But our favourite feature is: It is as little design as possible.

• More Features
– Auto-Start on login
– Activate on startup
– Activate with left or right click
– Acoustic feedback
– “Lockscreen allows sleep” option
– “Auto-deactivate on low battery” option
– Automatische Deaktivierung bei geringer Akkuladung
– Support for many languages
– Optimized for VoiceOver

Disclaimer: Theine will not prevent your MacBook from sleeping if you close its lid for security reasons.

• Caffeinate when…
– Watching or recording videos
– Listening to podcasts
– Doing a presentation at work or school
– Waiting for large files to download
– Talking to your friends
– Rendering sophisticated media files
– Observing live stats or long-running tasks on your screen

Simple elegance & efficiency

Been using this app through its various iterations for a few years now and have been pleased with its performance. Really like not having to deal with a Preferences page and being able to handle that aspect through the icon drop down menu. It does what I need it to do and makes my life easier by eliminating the annoyance of having to deal with screen timeouts.

BUG after recent update

Overall this is an awesome app. But recently there seems to be a BUG that: once system switched to/from night mode, the app icon in top menu become unclickable, also it's not showing full icon. Please fix. Thanks.

Works. Good design.

Works well. Doesn’t even need a Preferences page because all of the functionality is in the menu. You can also toggle it on and off by just clicking the icon. However it keeps asking me to leave a review, which is the only reason I am leaving this review. If it doesn’t make it stop reminding me, I’ll soon be using a different app…

Developer Response ,

Dear KevinThr, thanks for you feedback. The ask-for-a-review behaviour was not intended and I fixed this in the current update (Version 2.0.1). It would be great if you could reconsider your review. Kind regards, Martin
