I have a macbook pro and use it all of the time. use the file below, put it in main hd/library/modem scripts then reboot and then connect your 8100 via bluetooth and after pass key is put in select "Use a direct, higher speed blah blah" select continue user guest pw guest gprs cid string wap.voicestream.com modem script BlackBerry 8100 everything else default. Are you with tmo? Remove the .txt from the file it would not allow me to add it if you have trouble I will stuffit. Hope this helps
