I've used an old version of this product for many years. I emailed the developer to ask whether the current version was compatible with MobileMe. He replied to say that I'd have to pay to upgrade to the latest version before he would answer my question! It's a shame because I'd always liked the product but there's no way I'm going to pay $50 to have such a simple question answered.

Anyway, I've now found SuperFlexibleSynchronizer which seems even better than Synchronize Pro and is cheaper!
