MX Master 4 Haptics Control

Haptic feedback for the Logi MX Master 4 mouse on macOS. Every left click is followed by a vibration, so you feel each press without looking at the screen.

Version 0.1 · Apple Silicon (M1 or newer) · about 60 MB

Features

• Vibration on every left click, in any app.
• 15 vibration types: Sharp Collision, Knock, Mad, Jingle, Firework, Wave, Ringing, and more.
• Turn the feedback on or off with one switch.
• Your chosen vibration type is saved between launches.

Requirements

• A Mac with Apple Silicon and macOS.
• Logi MX Master 4 mouse.
• Logi Options+ with the HapticWeb plugin installed.

Installation

1. Download and open the DMG file.
2. Drag DSMasterHaptic into the Applications folder.
3. On first launch, macOS may say the developer cannot be verified. Open System Settings → Privacy & Security and click Open Anyway.
4. If that option does not appear, run this in Terminal and open the app again:
   xattr -dr com.apple.quarantine /Applications/DSMasterHaptic.app
5. Grant Accessibility permission (System Settings → Privacy & Security → Accessibility), then turn on the feedback switch in the window.
