title: Configure mouse in tmux on OSX
body: <p>It seems that mouse support changed in one of the recent versions of tmux and every article I am finding on the subject uses outdated settings. All I want to be able to do is use my mouse to scroll when in scroll mode and use it to copy/paste with the left button like it usually does in a terminal. Unfortunately, if I set <code>set -g mouse on</code> the copy/paste doesn't work and if I set it to off, scroll doesn't work. I am on OSX 10.12 Sierra if that makes a difference and I am using the default Terminal app.</p>
