I just got the Curve 8310 today. I have a MacBook and every time I connect my phone to the computer to put music on, it doesn't show that my phone is connected. But, I was able to sync my addressbook from my computer, so I know that it's reading some kind of connection. HELP! I replaced my iPhone with a BlackBerry, so music is important to have to me!
If you have a media card, go into the media card options on your BB and enable mass storage mode. You will then be able to browse to it on your Mac as if it were a USB storage device.
