I'm not sure what's going on, but I used to synch using a PC until I got my Mac. I recently installed the Mac DM (latest version), tried to sync, but it will not transfer all of my BB calendar info to my Mac. It also won't transfer the information to my work PC. It will only transfer the most recent information entered either on the machine or BB. Also, when I sync, It will not remove the existing info on my BB. What gives?
