I've reset my computer and now tmux is complaining about my .tmux.conf having these directives:

setw -g mode-mouse on
set -g mouse-select-pane on
set -g mouse-resize-pane on
set -g mouse-select-window off
set -g default-terminal "screen-256color"

with these errors:

/Users/mdurrant/.tmux.conf:24: unknown option: mode-mouse                  [0/0]
/Users/mdurrant/.tmux.conf:25: unknown option: mouse-select-pane
/Users/mdurrant/.tmux.conf:26: unknown option: mouse-resize-pane
/Users/mdurrant/.tmux.conf:27: unknown option: mouse-select-window

So I have to comment them out, but then my mouse doesn't work in tmux, which is a pain.

How can I enable the mouse in iTerm2 with tmux?

This works on my other Mac.

I use tmux version 2.1.

This looks like a change in tmux in 2.0 -> 2.1

I've replaced

setw -g mode-mouse on
set -g mouse-select-pane on
set -g mouse-resize-pane on
set -g mouse-select-window off

with just

set-option -g mouse on

and everything seems ok

    mouse on configures the following: The default key bindings allow the mouse to be used to select and resize panes, to copy text and to change window using the status line., so it's the equivalent of setting mouse-select-pane, mouse-resize-pane and mouse-select-window as on. Probably close enough to the original configuration; though not exactly the same. – davidjb Aug 06 '16 at 07:05

mode-mouse isn't support on tmux. Try use on ~/.tmux.conf

set -g mouse on

and run on terminal

tmux source-file ~/.tmux.conf

Work so good on my computer, it can scroll, change panes...
