Festivitas, a new macOS app, allows users to add customizable holiday lights to their Mac desktops. Developed by Simon B. Støvring, the app offers various customization options, including cable thickness, light size, spacing, drop height, flashing pattern, speed, and color.

Users can choose between colored and white lights and can selectively disable lights in the dock or menu bar to avoid interference with other elements. The app requires macOS 14.6 or later and needs Accessibility settings enabled. To deactivate the lights, simply quit the app.

Festivitas is available as a name-your-own-price download on the developer's website. Støvring notes that users have been paying between €4 and €30 for the app. For those interested in further enhancing their digital environments, consider exploring options like Festivitas App Brings Holiday Cheer to Your Mac.

This festive addition joins other developer-focused apps from Støvring, such as Runestone, Scriptable, and Jayson. While Festivitas adds a touch of holiday cheer, those looking for more substantial productivity enhancements might be interested in tools like One UI 7 Beta: Vertical App Drawer and Knox Watermark or One UI 7: Samsung's Major Android Update.
