A few weeks ago I talked to the tech guy at hasselblad. I am thinking about upgrading my laptop (from an older Macbook Pro to a Newer one) and he said to steer clear of the Retina Display Macbook pro because it does not have a FW800 port, he said they have been getting lots of complaints relating to people using the thunderbolt ports with adapters, and that it would be less reliable for tethering. Any one shooting in the real world confirming this?
