Following the lead of the MacBookPro introduced a few months ago the new Mac Pros, Mac Minis, and iMacs include FW800 ports but not a single FW400 port. In the case of a Mac Pro you can add a PCI card for direct use of your existing FW400 cables. In the case of the Mac Mini or iMac (or an alternative to the PCI card) you will need our FW400 to FW800 cable which we’ve tested with our Phase One digital backs.
