**Short description of error**
Orbiting around an object has an opposite direction while using Apple Magic Mouse or a MacBook trackpad's scroll.
**Exact steps for others to reproduce the error**
1. Shift and scroll with Apple Magic Mouse — panning direction is correct.
2. Scroll with the Magic mouse — orbiting direction is opposite.
My guess for this UX fix: ‘view3d.rotate' must be somehow negative for the 'mouse/trackpad pan’ action on macOS to conform with its natural scroll feature.
