Default [Q] (Q) How do i sync contacts with mac?

I am sorry if there are someone who have discussed this before.
so far i have already search through the forum, no solution given.

here is the problem, i am using HTC Desire VC (Dual Sim Card Taiwan Version)
I am having problem transferring/backup my data to my iMac. Could anyone please help me with this?
any software that could solve the problem, or how do i do it to sync with my Contacts on iMac or maybe the Microsoft Outlook for Mac.
thanks in advanced.
