unknown option: mode-mouse with iterm, tmux

Solution 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

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...
