Après contact avec le support de Hanbase, il est confirmé que la version MacOS de l'appli Handbase nécéssite une base de donnée tiers et ne peut synchroniser directement entre Palm et Mac (via export / import de fichiers CSV - bref la galère).
Ci-dessous la réponse du support pour les anglophones (ou non anglophobes !)

Question
"I am considering purchasing Handbase to run on my new iMac at home. It seems from that the Mac Desktop companion does not allow to create the database and especially customise its appearance. How can I do that ?"

Réponse
"This is correct. The Mac version of HanDBase Desktop does not have
those features at this time. There is a more full featured version
planned for the future, but I don't have any specific details or
estimated dates available for it, yet."
