My primary machine is a MacBook Pro, and it has no problems scrolling Firefox or Chrome. Neither does my dual boot Win10/Linux workstation downstairs. I think choppy scrolling is mostly a trackpad issue in this case, TBH. The settings aren't quite right. Disabling pinch zoom gesture improves things a bit, but for $2900 I expect that I wouldn't have to resort to hacks to get the core functionality working.
