With the release of 64 bit MacOS Catalina 10.15, older 32 bit apps such as JaVaWa GMTK are no longer compatible. With the author of the app down with illness, it's unlikely it'll be updated. Just wondering here if anyone has found an alternative on the Mac platform to rename and change MapID amongst others to permit installation of OSM maps on a Garmin device.
Any pointers would be highly appreciated.
