A big thanks for the replies. I tried a google search whilst sitting in the hotel in Paris the other day, "pilot log book mac os X", not much joy . I tried others too and found one which is set up for gliding, but not for airliners. Just depends on what you put into the search i suppose.
I wil conitnue to search as I am starting to dislike working through Virtual PC 6 for my current logbook. If I knew a litle more about my MAC OS X 10.2.6., I would dearly love write such a program.
I look forward to the ultimate program for OS 10.2.6
