For synchronizing Outlook contacts, calendar, bookmarks, etc. with your Android and HTC Smart phones, you can use HTC Sync.
Unfortunately, HTC Sync is a Windows-only application, leaving the rest of the Mac users with very little option to synchronize data between Mac and HTC phones.
There doesn’t seem to exist a single, official all-in-one application for the Mac to seamlessly sync contacts, iCal, music, videos and photos with Android phones. Really, HTC, how difficult can it be for you to come up with a minimal version of HTC sync for Mac?
HTC Sync Alternative for Mac:
Nothing comes close to HTC Sync, yes, but here’s an attempt to achieve syncing of data between Mac and HTC phones. So, if you wish to sync data between your HTC Android phones and Mac, you can use Google’s cloud services and Mac applications.
For example, say you want to sync your HTC phone’s contacts with your MacBook Pro, then open Mac’s Address Book, from the menu click on Preference, go to Accounts and check the Synchronize with Google box for syncing the contacts.
Similarly, if you want to sync Gmail, use Apple Mail to get all the emails on your Mac. And to sync the calendar data, Mac has an iCal application which can be configured to pull the data on your Mac.
Commercial applications: If you are searching for a paid solution to sync Outlook contacts, calendar, tasks and notes, then Companion Link for Mac is worth a shot ($39).
Freeware applications: If you want to organize and sync iTunes playlists, videos and photos on your HTC Android phone, check out doubleTwist. Also, the free version of Sync Mate does a neat job in syncing iCall, Address Book data to your HTC phone.
