Sebastian, ci sono delle ottime notizie per te:
A partire da oggi, puoi utilizzare il tuo Magic Trackpad 2 sottosopra con BetterTouchTool:
BetterTouchTool 1.93 (October, 23, 2016)
Fixed some little Sierra issues regarding keyboard shortcuts
You can now choose whether a normal mouse button should trigger on mouse-down or on mouse-up (click the little gear icon left to the
mouse button selection)
You can now repeat an action while a mouse button is pressed (click the little gear icon left to the mouse button selection).
Added option to mirror the Magic Trackpad orientation for upside-down usage. It's in the advanced trackpad options => General
