Hello, since I use mac os “Sierra” my trackpad is now much too fast when I use two fingers to zoom in and out. While moving tools is normal with a single finger.
It was not the case before with Mac os ElCapitan.
When I use the mouse wheel everything is normal
But as I installed Sierra and the update of Sketchup 17.1.173 at the same time.
I do not know who is responsible.
Have you encountered this problem?
