I'm on OSX and mouse-support. vim bindings, clipboard, and extended scrollback in tmux "Just Works™" in both Terminal.app and iTerm2. The only external software that I had to install separately is reattach-to-user-namespace to get the clipboard working.
The only problem I encountered was really bad kernel panics when the tmux server exits (i.e. last session is closed), but it has been fixed as of tmux 2.1 as far as I can tell.
I'd say give it another try; the problems you were having might no longer be an issue now.
