If you’re looking to add a little holiday cheer to your Mac, be sure to check out Festivitas by developer Simon Støvring. The app lives in your Mac’s menu bar where you can switch between displaying colorful blinking holiday lights along your menu bar, dock, or both.

The app requires access to accessibility permission to tell where your Mac’s dock is, which it will ask permission for when you first start it. Once that’s out of the way, you can turn the lights on and off from the menu bar, where you can also access settings to customize things like the size of the lights, their spacing, and the thickness of the wire that connects them.

The app is available via Gumroad for 4 euros.
