I have not had success transferring files via BT on my Mac... connect your Berry, enable mass storage mode, and drag and drop to your media card (assuming you have one...)
If you do not have a microSD card, get one!! Because you are missing out... and it is much easier!! Also saves your device memory!
When I connect the blackberry to my mac nothing happens, just on the screen of the BB a message displays the current is not large enough to charge the phone. I tired installing the BB tools software and nothing comes up when I open the programme!!?? any ideas?
