Your lights, in sync
with your Mac.

Blask Sync is a free menu bar app that turns your Philips Hue lights into an ambilight for your screen, or makes them move with the music your Mac plays.

Latest release · macOS 14.2 or later · Apple Silicon & Intel · Free and open source

The lights behind your monitor follow the edges of the picture.

Why Blask Sync?

Philips' own Hue Sync app for Mac is no longer supported. Blask Sync was made to keep your lights in sync with your screen and music on today's macOS, as a small, free and open-source app.

Three ways to light up

Pick a mode from the menu bar. That's it.

Choose Screen, Music or Manual and press Start. Blask Sync streams colors to your lights over the Hue Entertainment API, so they react without lag.

Screen

Strips behind your monitor follow its edges and lamps around it pick up the mood of the scene.

  • Captures up to 60 frames per second
  • Smooth easing with four intensity levels
  • Saturation boost keeps colors vivid

Music

Your lights ripple with whatever your Mac is playing: Spotify, Apple Music, YouTube, anything.

  • Beat, bass, mid and treble detection
  • Flow and Pulse styles, four palettes
  • No virtual audio driver to install

Manual

Paint your lights yourself on a color wheel with a pin for every light, or pick a ready-made scene.

  • Recolor lights one by one or together
  • Warm, neutral and cool white scenes
  • Colors stay on after you quit
Made for your setup

Every light where it really is.

Drag-and-drop light mapping

Place each light around a picture of your monitor. Each one follows the part of the screen you point it at.

Find lights while you move them

While you arrange them, each real light glows in the color of its marker, so you always know which is which.

Gradient strips, segment by segment

Every segment of a Hue gradient strip gets its own color. Lamps beside the screen blend toward the whole picture.

Back to normal when you stop

Stop syncing and your lights return to how they were before, or switch off if you prefer.

Lives in the menu bar

No windows in your way. Sync keeps running in the background, and the icon lights up while it does.

Private by design

Everything happens on your Mac and your home network. Your screen and audio never leave your computer.
