Ask HN: How to make work copy and paste with MacOS sierra, tmux2.6 and iterm2

Hello, I am looking how to make copy and paste work for MacOS sierra + tmux2.6 + iterm2

It drives me crazy, and can't find a solution without problems. Maybe somebody on HN got a similar setup and could share his tmux.conf.

Basically, I want to have one clipboard for vim / iterm2 / tmux and whole system
