My mp3 music is on a Mac.. Cant sync it?

I run Leopard on my mac . . .
(I'm not quite sure you can get the Mac to recognize the Versa without a memory card in your phone.)
I plug the USB in, go to Menu>Settings>Tools>USB Mass Storage . . . thats pretty much it. 
An icon shows up on my desktop and I am able to browse, change the file structure, etc. on the card memory, just like an external hard drive.
I'll double check when I get home, I can't remember if the Mac recognizes the phone memory or not (IMO, I really don't care because I keep EVERYTHING on my card and leave the phone memory blank).
I'll let you know.

Turn on Bluetooth and then choose Set up Bluetooth device and follow the instructions to pair your Mac with your phone (it should be pretty clear).  I don't know why yours is freezing; is all your system software up to date?  After pairing, in the Bluetooth menu, there should be a item called Browse Device and then supposedly you can view all of your files.  Transferring will be very slow though.  I can't get my Leopard system to recognize my microSD through the phone.  I just bought a Sandisk USB card reader for that.
