sync htc / android phone with macbook / mac os x I use MacBook (which have Mac OS X 10.6 - Snow Leopard). How can I sync data between my HTC phone and my MacBook.

I have HTC Wildfire, and HTC Sync software only supports Windows.
As of now, there's no counterpart on Mac for HTC Sync.

You can however try MissingSync for Mac - which allows for syncing of contacts, calendars, notes, tasks etc. on Mac
