I have to say that it in my experience the hardware and software seems to have come such a long way. My bb7100i was a nightmare sync'ing with the old desktop manager and here we are a year later and the new setup works perfectly. Absolute plug-n-play versus the old 'mess around with it for days until you could get it to work marginally well' method. I would certainly give it a shot. Worse case, back up the bb and restore it/delete the software from your mac if its a total nightmare.
