In reply to Ulisse. I have no idea, sorry. Apple is really annoying in cutting backwards compatibility when it doesn't make sense. It's like dropping support for 32bit terminal apps that didn't make any sense already. There is no real offline alterantive. But yeah Garmin hasn't been forecoming at all either.

Good morning,
I have been using your maps on my Garmin GPSMAP 66sr for about four years now, and I have been extremely satisfied with them.
I plan my hikes using Garmin BaseCamp on a MacBook Pro M2 and regularly update the maps through your website. During all this time, I have never experienced any significant issues, and my workflow has become well established: I plan the route, transfer the track to my GPS, follow it during the hike, then download the recorded track afterward and archive it for future reference.
However, for the past few months, whenever I start BaseCamp or other Garmin applications, I receive a warning stating that support for Intel-based applications is coming to an end and that these programs, or some of their components, will no longer work with a future version of macOS.
I am currently running macOS 26.5.1, and I am concerned that once macOS 27 is released in September, I will no longer be able to use the Garmin software that I rely on today.
For this reason, I contacted Garmin Italy to ask whether any updates to BaseCamp were planned. The current version is 4.8.13, released on March 31, 2023. Unfortunately, I was informed that no further development of BaseCamp is planned and that the only remaining solution will be Garmin Explore, which on macOS is available only as a web application.
I would therefore like to ask whether you are already aware of this situation and whether you have identified any alternative software that would allow me to use your maps on macOS to plan hiking routes and manage a Garmin GPS with functionality similar to what BaseCamp currently provides.
Thank you in advance for your time and attention. I look forward to your reply.

Kind regards,
Maurizio

Ciao, ho scaricato le curve di livello separate per il Nepal, tuttavia, quando estraggo il file .zip delle curve livello, all’interno non trovo le cartelle 7* (che dovrò copiare nella cartella product1).
Trovo tanti file .img che iniziano con 7* e diversi numeri successivi.
Ho provato a copiare quei file e successivamente seguire la procedura (copiando nuovamente il file info.xml) tuttavia non funziona.
Premetto che tutto questo contestualmente alla prima installazione della mappa su Basecamp (senza che l’abbia visualizzata prima).
Come posso fare?

In reply to austinstratton1. yes sadly on mac osx the switching layout in bAsecamp first is the only way possible nowadays.

In reply to extremecarver. I am not sure what the issue exactly was. I did a fresh install following your tutorial and the contour lines all show up correctly now. I am using the Classic layout and some are labeled and all can be read by mouseover. Thank you! It works great on my GPSMAP device. I also have a fenix 6, and have used your Gmapsupp.img previously to load devices. I am on a newer Mac OSX device. If I want to use the Fenix layout instead of default Wide, would the recommended process be to change the layout on my Basecamp map file and then send from Basecamp?

In reply to austinstratton1.

That’s very strange – there may be a cache issue? Can you delete the cache first and check again. It should be identical to maps which come with integrated contourlines (you could try Andorra as it’s a tiny download). Depending on which layout you chose – there may not be labels for the contours, but they will show up on mouseover. However also could be some sort of cache issue (though I don’t understand why the contourlines itself then show up).

Hello, I recently downloaded mtbus-northeast.gmapi and following the instructions I was unable to activate 20m contour lines with the included files. Following other comments, I also downloaded contours_us-northeast20m.gmapi and copied its contents from the Product1 folder into the mtbus-northeast.gmapi Product1 folder. I also copied the Info.xml file for 20m contour lines in the mtbus-northeast.gmapi Layout Files folder. The contour lines now show in Basecamp, but they do not show elevation labels. I am only seeing one label of 984ft without any others. Can you advise if I may be missing a step?

The mac osx spain contourlines download – after unpacking – contains loads of 7* folders (meaning folders starting with 7) – it’s those that you have to copy as under step 2ab) in the instructions. Look at the pictures of the instruction – once you understand it it’s pretty easy.
