MacOS Touchpad Behavior Analysis

Single Touch

On a MacBook Air with 104mm x 76mm touchpad, macOS appears to put its equivalent of upper_thumb_line 20mm from the bottom, and lower_thumb_line 10mm from the bottom. On Magic Trackpad, 130mm x 108mm active area, these seem to be the same (20mm/10mm from bottom).

In AREA, i.e. above upper_thumb_line

• Finger: Live touch, no speed threshold, free movement
• Thumb: Live touch, no speed threshold, free movement

Below upper_thumb_line but above lower_thumb_line
