Its not quite as fast as ICS, but I still get DL rates of over a gig on my Macbook with Mobile Stream's USB Modem.
It has a free trial, so give it a try

As for the bluetooth question above my post, make sure your device is on visible. Assuming you're running leopard, once they're paired you just turn on ICS, and under bluetooth on the mac you should see your TP device name under devices. Hover over it and click the "Connect to network"just like Stevedusa said
