I'm in a similar situation (hooked on Xmonad, but cannot run Linux). I've tried various solutions over the years, but the only one I've found acceptable so far is a full-screen iTerm2 running tmux. I use `bind t split-window \; select-layout main-vertical` to emulate Xmonads default layout behaviour. It works because I spend most of my time in the terminal anyway. I miss having the browser - and the video player when doing repetitive or otherwise boring tasks! - in a pane, but keeping other apps out of the tile-management is fine as I'm, more often than not, switching context anyway.
