hi guys... can i know how to sync my nokia n73 to my leopard?

I believe " PC" suite will not work on mac... right?

yeah, u can use USB or Bluetooth actually, if u want to use bluetooth. active ur mobile and ur mac bluetooth, click on iSync ( go to application folder) then u can add ur device there. happy with mac.

u can send stuff thru bluetooth , eg: songs , pics , themes .

that's y apple invent iPhone.
they just sync nicely with Macs

yes no problem at all, but not using iSync. just pair ur computer with ur mobile with bluetooth. with bluetooth u need to send it to ur mobile with the bluetooth wave but if USB will be faster cause using the USB speed.

Mac OSX works easily with any phones...
SE, Nokia even chipalak China phone .... just connect and it works (USB charging,transferring file etc)

While connecting SE to Windoze sometimes piss me off... always ask me to install this and tat...

Actually as a current iPhone user and a former SE/Nokia user, aside from music/video the sync capabilities with SE/Nokia is way better than what you get with the iPhone. For example with the SE/Nokia, iSync and Addressbook on Tiger, I could receive and send SMS via bluetooth from the computer which is way faster and more convenient. Like it or not the iPhone is still a 1st gen product with lots of shortcomings IMO.

To the original poster, iSync + Address Book + iCal + Bluetooth File Exchange + iMovie are all part of recent OSX releases. Together they provide syncing between your N73 and the Mac. It's a far more elegant solution. For example if you have a movie in iMovie, export to Bluetooth will automatically compress it in 3GPP format and transfer it to your phone once done.

You just have to see it in action to truly appreciate the capabilities of OSX and a supported phone.

I've been using this for about half a year now, occasionally you get repeated calendar items, error syncing, no choice really. You could try Pocketmac:-
