OK. I have a Mac which I love dearly. I have paired my 7250 and the mac quite easily but I want to do file transfers. I'm not looking for anything fancy, I just want to use the BB's storage space to be able to transfer files to and from the BB and the Mac. So, first can I do anything other than simply pair the Mac and the BB? Second, if I can, how do I upload software like dictionaries, etc., to the blackberry?

I'm not even going to answer this since it is asked so frequently and answered several times this week alone.

End of rant. The BB does not support Bluetooth data transfers at all. As of now, all you can do is use a wireless headset, and a few new Bluetooth keyboards. No syncing, file transfers or updates at all.

Data can't be transferred using SerialPort?

From the Mac, your choice is PocketMac.
It will sync your PIM.

i ahven't used the BB with a MAC yet, i am thiniking of making a purcahse once the new mactel machines are out.

upload files to a website host, point your browser to it and download them. I have trans ringtones and pics this way no problem.
