How can I retrieve the data of my old HTC device backup on my Mac, to get all my contacts back?

[fouti55]

The backup was created through HTC Sync Manager back then ; my HTC mobile was stolen and therefore I have no access to it, just a backup on my Mac of its content.

HTC Support is better place to ask this question.
If your phone was connected to your Google account, your contacts are over there.

Thank you for your answer !
I did call HTC ad they said that as far as they are concerned, there is nothing to do but admitted some 3rd party softwares can do the trick (without naming any one of them..)

Anyone else has something to suggest, I am totally lost with that issue AND Still am sure a software / something exists.. ?
