Halo MultiSpeakers

Un-greys your volume slider

Only for Mac

Free

Mac

One volume for two Studio Displays or any Multi-Output Device. Halo un-greys the slider macOS disables, with a proper HUD. Run two Studio Displays, or any speakers-plus-headphones combination, through a Multi-Output Device and macOS gives up on volume. The menu-bar slider greys out, and the only way to change the level is one speaker at a time in Audio MIDI Setup. Halo fixes it. It is a small menu-bar app that writes the volume to every speaker in the aggregate at once, so they all move together. Drag its slider or scroll on its icon, and a proper HUD shows the level on the display you are using. • Scroll-wheel volume on the menu-bar icon, in 32 fine steps • A slider that works when Apple's is grey • A proper volume HUD on the display under your cursor • One-click Create Halo Speakers for two or more Studio Displays, drift-corrected so they never fall out of sync • Levels remembered across reboots WHAT HALO NEEDS macOS 15 or later, on Apple silicon or Intel. Two or more Studio Displays for the one-click setup; any other Multi-Output Device works once you have created it in Audio MIDI Setup. Halo does not ask for accessibility access, so the keyboard's volume keys stay with macOS. Use Halo's slider or the scroll wheel instead. NOTHING LEAVES YOUR MAC Halo has no account, no analytics and no network access. It is sandboxed and talks only to CoreAudio. Your volume levels stay in the app's own preferences. Halo is free.
