Hi,

I want to add to that, that first of all, BaseCamp is pretty good too.
Next thing is, you can easily share maps between windows (if you still have some) and mac.
I have a MapSource VMware session still inside Windows, just to get non-gmap maps converted.

But on windows, we can also use GMap folder.
It is quite easy actually:
Place the .gmap file anywhere on a large disk.
Richt click on the .gmap file inside the new location, and select: Create Shortcut.
Move that shortcut to the following folder, depending on your windows version:
Windows XP -> C:\Documents and Settings\All Users\Application Data\GARMIN\Maps
Windows Vista -> C:\ProgramData\GARMIN\maps
Windows 7 -> C:\ProgramData\GARMIN\maps

For mac, the install is the same (although the GMap folder looks like a file on MAC (but it isn't !! )
So, on the MAC:
Copy the .gmap file to the $HOME/Library/Application Support/Garmin/Maps directory.
To make the map available for all users, please create the following directory if not already there:
/Library/Application Support/Garmin/Maps, and please the .gmap file in that directory instead.

If you want to place the files elsewhere, please put all your .gmap files in that new directory, and create [Only registered and activated users can see links. ].
i.e., if your new path is /Users/Shared/Garmin/Maps/, please execute the following command:
Code:
Please Login or Register to see the links
Naturally, if the original target directory for the link is already present, please make it empty and remove it first otherwise you can not create the symbolic link.

If required, please use the MapID to unlock your map in JetMouse (which is not there for MAC yet, who owns the source for this tool? I can write it down into a native mac app if I would know what it exactly calculates.),
and enter the new key into the Garmin MapInstall.app program,
via the Unlock -> Edit Unlock Codes, menu option.
