How to disable Magic Mouse horizontal scrolling

Ok, back to the issue at hand. Unfortunately, macOS doesn't provide a direct toggle to disable only horizontal scrolling via System Settings. However, there are some potential optoins to work around this:

Option 1: Adjust Tracking and Scrolling Settings in macOS

1. Go to System Settings:

• • Click the Apple menu  > System Settings.
  • Navigate to Mouse under Input Devices.
  • Reduce the scrolling speed to minimize sensitivity, though this affects both horizontal and vertical scrolling.
  • Ensure gestures like "Swipe between pages" are disabled to prevent accidental gestures.

Option 2: Use Third-Party Software

Apps like BetterTouchTool or MagicPrefs offer advanced customization options for the Magic Mouse. You can disable horizontal scrolling specifically using these tools.

Option 3: Use Terminal to Adjust Scrolling Behavior

If you are comfortable with using commands in the Terminal, you can attempt to adjust the scrolling settings using this command: defaults write com.apple.driver.AppleBluetoothMultitouch.mouse MouseHorizontalScroll -bool NO
