Need a Media card on the Bold
First pair the Mac and the Bold using "Bluetooth Setup Assistant" on the Mac
To send the file:
On Mac: open "Bluetooth File Exchange" app ; use cmd-O to select the file ; hit Send ; select the BB in the selection list and press Send
On BB open the "Media" app and select menu item "receive using Bluetooth" ; select the location and name and click "Save"
Use the pre-installed "To Go" apps by Dataviz to open the file
Attach to an email and send
I found this useful at a building where I did not have an Internet connection and my USB cable was not handy.
If the USB cable was available, I would have attached the Bold in "Disk mode" and copied the file over.
