Software: OS 10.5.6; Nokia Device Browser v.1.91; Nokia Map Loader 1.0; Nokia Maps 2.0
Hardware: Nokia N95 (S60 3rd Ed.); MacBook Pro (MBP)
The cons: It was difficult to get the MBP to communicate with the N95. In the end, a re-format of the N95s MiniSD card did the trick.
The pros: The Nokia Map Loader worked perfectly via a USB connection once the software/hardware (MacBook Pro & N95) was installed and properly configured. Map downloads and transfers worked without a hitch. The application interface is very intuitive. In particular the "history feature", which keeps track of installed maps is useful. I would definitely recommend the Nokia Map Loader to Mac/N95 owners.
Many thanks for generating this app. It should have been available much earlier as part of the installation CD one gets with the N95 purchase.
