I have a 2009 MacPro 2.93 Ghz, (4.1) running Yosemite. According to the CAT charts, I should able to activate Continuity with either a Bluetooth 4 Dongle, or adding a new updated Airport card. When I run the tool, it halts at "Plug in a USB Bluetooth 4 dongle to add support, which I did, and tried 2 different IOGear dongles, both of which worked on my MBP to activate continuity... ) Does not seem to even see the dongle. This Machine was a CTO, and does not contain a built in Airport card. Safe to assume I need to install this too? Thanks in advance!
