I’m using Cubase LE 8 on MacBook Pro 13" Early 2015 macOS Sierra (10.12.3).
After updating to macOS 10.12.3 from 10.12.1 scrolling with trackpad has broke for me.
It feels like trackpad is emulating mouse, “camera” moves twitchy. It seems like has some kind of threshold which after crossing just switches like I pressed button instead of swiping on trackpad.
Maybe someone encountered the same problem and found out the way to solve it.
