    Ron Jones' spreadsheet, the latest version of which was just released to NavList yesterday, is a good choice.  My own Celestial Tools (www.celestialtools.webs.com) works on a Mac under Wine, as I suspect Rodger Farley's Teacup Navigation (http://www.teacupnavigation.net/CN.html) will.  These three programs are free, but may be much more than you are looking for.

    Some quick thoughts
    1) http://www.celnav.de/ Hemming Umland implemented some nice
    javascript code for ephemeris and sight reduction - save the web page
    and run it in any browser. Worked fine on my MacBook Pro
    2) Any of the various spreadsheet implementations - quite likely work
    in OpenOffice Libre Office if you dont have Microsoft eg
    3) CelNav https://github.com/ms8r/celnav is a python program using the
    python ephemeris library (you can use this directly it is very easy to
    use with a minimal level of python programming). It is part of the
    Navigatrix distribution - custom Linux for cruisers. I dont remember
    trying it when I had a mac but I certainly ran other python code.
    4) OpenCPN runs fine on a Mac, does the Celestial Navigation plug in
    work on a Mac though? I cant remember!
