You can simply take the gmap folder from the PC install in Post #3 and unlock it as SF said in Post #5, if you can't unlock in mac OS just borrow a Win machine, even XP will do. Then you can place the unlocked gmap folder on your Mac in /Library/Application Support/Garmin/Maps/*.gmap. It tells you how in the very first thread listed in the [Only registered and activated users can see links. ]: [Only registered and activated users can see links. ] [look for 'Have you downloaded a Gmap folder ?'].
