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

• It just works
Caffeinate your Mac with a simple click on its menubar icon or define a custom global hot key. It is fast, lightweight and works great on macOS 11 and above.

• Always on time
The timer feature allows you to control exactly how long Theine should be activated. You can 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 optimised for high-definition retina displays. It follows the idea “as little design as possible”.

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

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

• Caffeinate when…
– Having a conference call or video chat via Zoom, Google Hangout, Microsoft Teams, Skype, etc.
– Watching or recording videos
– Listening to podcasts
– Doing a presentation at work or school
– Waiting for large files to download
– Rendering sophisticated media files
– Observing live stats or long-running tasks on your screen

Great Simple App

No upsells, no in-app purchases, no subscriptions... it's so nice to find a simple utility that just does one thing well.

One annoyance is that it seems to keep asking for ratings and reviews, regardless of whether you already *have* submitted a rating or review.

It should really only ever ask for a rating/review once at most, so I hope the developer does fix that in the future. It's the only annoying thing about this otherwise flawless app!

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.

Does what it says on the tin

Sometimes, you are doing a Thing without touching the keyboard or mouse. Your computer can't tell that you are doing a Thing. It dims its screen, starts the screensaver, goes to sleep, or otherwise interrupts the Thing because it assumes you are not using it.

Would you like to do Things without being interrupted? Install this little app.
