Donate to Openmtbmap - and download readily converted maps
If you don't want to convert the maps, I converted the most popular openmtbmaps / velomaps ready to be used with Basecamp or Roadtrip in gmap format for Mac OSx. Simply look at the bottom of the download page for them (only available to donators)
Don't convert but use Qlandkarte GT
just accept that Garmin programs for Mac OSx are lousy - (well the whole OS is as lousy as Windows, but with fewer people using it, I wont give a damn for it - best treat your Mac hardware with a good OS like Ubuntu Linux instead of junk with nice eye candy).
However Qlandkarte GT is working splendidly with the openmtbmaps, and is easy to learn. Only drawback is, that there is no autorouting support for garmin maps (yet). You only need to extract the maps to a folder of your choice then use Qlandkarte GT.
Don't convert but use gmapsupp.img import by Basecamp
The irony of Basecamp for MacOSx not reading in the standard .img format, is topped up, by the fact that it reads the nearly identically structured gmapsupp.img files.
So use Windows Basecamp/Mapsource or gmaptool or mkgmap or sendmap to create a gmapsupp.img - put it on a external harddisk or flash memory (you could also put it onto your GPS, but than it's slower) and import it into Basecamp. This way you also don't have to actually convert the maps.
Convert the maps:
See several possibilities on how to do it below:
Convert the maps with gmapibuilder
wiki.openstreetmap.org/wiki/Gmapibuilder
To unzip you can use: http://unarchiver.c3.cx/unarchiver
Convert the maps yourself under Windows with tools provided by Garmin:
Unfortunately you need an Windows installation for converting the maps. Principally you have to:
1. Install the maps with install.bat under Windows (You have to have Mapsource installed)
2. Downlaod, install and run Garmin Map Converter for Windows
3. Downlaod and install the Mapstall/MapManager package to your Mac to complete the migration Garmin provides detailed instructions how to do this http://www8.garmin.com/support/download_details.jsp?id=3897 See also http://www8.garmin.com/macosx/index.jsp
Alternatively you can use Sendmap to transfer the maps to your GPS (see Tutorial (still to be written))
You could also install Qlandkarte GT - you will have to compile it first though. Builds are only available for Windows (plus easy installation on Ubuntu - but probably added into repos soon anyhow).
BTW: As all my maps are published under CCBYSA 2.0 / The new Openstreetmap Licence - you may share your mac map files freely - as long as you contribute openstreetmap.org and openmtbmap.org and stick to the same license. Unfortunately you need an windows installation for converting the maps to "Mapsource for Mac" aka Roadtrip.

Convert and Install the maps yourself using Mac OSX only (description provided by Tom):
Required software:
Steps:
scusate per gli errori, ma il correttore automatico di mac, ha colpito ancora; ri-posto la domanda:
-scaricate mappe openmtb per europa ed italia;
-decompresso il file, che ha creato cartelle con estensione g.map;
-per la conversione utilizzo gmapi builder;
-non riesco a convertirle in quanto, nelle cartelle non è presente nessun file con estensione *img (se nn si completano tutti i campi, il programma non permette la conversione):
come posso risolvere il problema?
grazie
Hi Albyspinmaster – there is no need to convert – the OSx files are already converted. Just install them (either Mapinstall or simply by moving them to the correct location):
https://openmtbmap.org/tutorials/install-maps-mac-osx/
(that’s the reason this topic is archived. The conversion was needed before I offered the OSx files directly for download).
grazie per la veloce risposta; decompresso il file, sul mac (Osx sierra 10.12.6) me lo fa vedere come cartella e non riesco ad aprilo con garmin map manager.come posso fare? grazie
Look here: https://openmtbmap.org/tutorials/install-maps-mac-osx/ —- In case of Problems:
Usually you just move the .gmap folder to: /Users/YOUR_USERNAME/Library/Application Support/Garmin/Maps/
ho scaricato le mappe open mtb per italy e europa. Non rosico a convertirle con map builder, in quanto, nella cartella creata dopo la decompressione dell’archivio, non e presente nessun file con estensione dmg. come posso risolvere il problema?
grazie
I’m trying to convert the .gmap file to an img file on a Mac. All the instructions above are out of date and don’t work. For example in Tom’s (above) description he talks about unpacking the .exe file to get the .tbd and .bat files. Well there are no .exe files to extract in my map’s package contents. Also using JaVaWa doesn’t work as it can not find a .TBD file. The only Windows machine I have access to runs Windows XP and Basecamp won’t work on that as it needs a .NET framework which is not supported. Grrrr…
Any know how to do this on a Mac?
The .gmap are already converted. Nothing more to do for you! This instruction was for converting the .exe downloads to .gmap.
Here are the instruction how to install .gmap maps on your Mac: https://openmtbmap.org/tutorials/install-maps-mac-osx/
