Another solution is to run it through Codeweavers' CrossOver Office. Or, I suppose you could install Wine and run it direct, if you are more technically adept and willing to take some extra time and effort.
I find that QL v3.4 runs well on our MacBook under CrossOver Office Pro. There were some things that were a little odd at first (a year or two ago?), such that a person would have to click a button twice rather than once to get a calculation to run and a result to draw on-screen, but that was about it as I recall. More recent updates to the Codeweavers product have improved things, but I cannot recall whether operation is flawless at this point or not, as I am no longer using a Macintosh for my primary computer.
