Hi Leslie - I don't know what chipset my MBP uses; I can find out if
you really want (I'm sure Googling for it would work eventually).
That said: If I understand the current state of the USRP2 software, at
this time it doesn't matter because the USRP2 software component of
GNU Radio currently requires Linux. Although I'm sure folks are
working towards broadening OS support, who knows when that might
happen. I'm not actively doing GNU Radio development at this time (in
the 'ebb' part of the flow), so maybe someone who's more in turn with
USRP2 programming could correct me if I'm wrong. - MLD
