Theine

Keep your Mac awake

Stay ahead. Stay awake.

Your Mac, caffeinated

Prevent your Mac from falling asleep, dimming the screen or starting your screensaver. Theine keeps macOS awake just like caffeine does with you. The definitive anti-sleep app, continously maintained since 2015.

Theine app opened in macOS status bar, with its context menu opened, revealing some of the available preferences.
As little design as possible

Insomnia, made intelligent

  1. Shortcuts

    Caffeinate your Mac with a simple click on its menubar icon. Or define a global hot key. It even supports macOS Shortcuts for automation.

  2. Always on time

    The timer feature allows you to control exactly how long Theine should be activated. You can also set a custom default duration.

Well crafted and has all the features you would expect but better—should ship right with macOS

When it comes to caffeine, I don’t blink

  1. The upper right edge of a MacBook display shows the macOS status bar with the app Theine, and its menu is opened.
  2. A settings panel for configuring a global shortcut.
  3. A close-up view of Theine’s menu bar icon, which is the silhouette of a cup of coffee.
  4. Theine’s menu opened, showing all the available duration options.
  5. A settings panel, basically a huge horizontal slider, that allows to set a custom default duration.
  6. The playful welcome screen of Theine features a bunch of coffee beans that behave physically correctly and can be interacted with.

Theine will not prevent your MacBook from sleeping if you close the lid with no external monitor connected, for security reasons.
