+Working out which driver to use for a Mac when using a particular dive computer can
 require some experimentation. The libdivecomputer website provides a useful point from
 which to start: http://www.divesoftware.org/libdc/drivers.html. It lists a number of
 sites for manufacturers of the serial to USB chips which provide the necessary conversions.
 
 Here you have two alternatives. Either you try each of the major drivers in turn until
 you find the right one, or you follow some further steps to try and identify the right
