In reply to mgg:
+1 for RouteBuddy.
I had previously been a user of Memory Map on the PC but when I switched to a Mac a few years ago, I gave up waiting for Memory Map to produce a Mac version. I also negated the outsourced Anquet because the support had already ceased.
RouteBuddy was the only one producing the software and mapping to run natively on the Mac at a decent price. I have found a couple of minor nuisance points when using the Magic Mouse, but otherwise, I think it is great software and I run atlas on iOS to us th maps on mobile devices as well.
They do have regular offers on mapping, so you can save a few quid if replacing existing mapping ( as I did ).
