Magic Knob
Turn your Mac trackpad into a precision dial for volume and brightness
About Magic Knob
Magic Knob sits in the menu bar and turns your trackpad into a rotary dial. Rest two fingers and rotate to adjust volume or brightness with an on-screen HUD; click with three fingers for play/pause. Actions can be remapped to shortcuts, media keys, or per-app controls, with adjustable sensitivity.
It is for MacBook and Magic Trackpad users who want tactile adjustments without reaching for function keys. Needs Accessibility permission.
Apple Silicon only. A 14-day trial needs no account, then a one-time $9 early-bird licence (regular $25) unlocks it for life, with a 30-day refund.
