Some changes has happened in the last version of tmux. Suddenly the copy-paste was not running but had no time to research the reason until minutes ago:
``` bind-key -Tcopy-mode-vi Escape cancel bind-key -Tcopy-mode-vi 'v' send -X begin-selection bind-key -Tcopy-mode-vi 'V' send -X select-line bind-key -Tcopy-mode-vi 'y' send -X copy-pipe-and-cancel "reattach-to-user-namespace pbcopy" bind-key p paste-buffer unbind -Tcopy-mode-vi Enter bind-key -Tcopy-mode-vi Enter send -X copy-pipe-and-cancel "reattach-to-user-namespace pbcopy" bind-key -Tcopy-mode-vi MouseDragEnd1Pane send -X copy-pipe-and-cancel "reattach-to-user-namespace pbcopy" ```There are a couple of issues (#592, #42) related. Glad this amazing feature is back again.
