UPDATE: FoneSync now supports Wave.
Germany-based Nova Media has released FoneSync software that helps to sync your Samsung phone with Mac OS X. FoneSync gives an easy to use interface that will allow users to sync contacts and calendar entries from their latest Samsung device to Mac’s Leopard or Snow Leopard OS.
FoneSync currently supports models like M8800 Pixon, M8910, S5230, S5600, S7220, S7350, S8000 and S8300 and goes for Euro 19.90 in Europe while Americans and Canadians can snag it for US$19.95.
It is also possible to synchronize Samsung smartphones under Windows Mobile OS with Mac OS. I have found several applications for this purposes, the pleasant thing is they are free, I chose SyncMate as I found it quite user-friendly.
