I am running a Mac Mini (1,66Ghz with 1G ram etc). It has build in BT and I am able to pair with Nokia6230 but with Centrafuse I can not call. How come?
I suspect that if you disabled the onboard bt before installing the CF bluetooth, then reinabling it after it might work. I used an extra bt dongle laying around. but you still need to disable the onboard bt to work properly
