I’ve got one hooked up to my 2008 Mac Pro using a Firewire 400 to 800 but have not tried it using Thunderbolt to firewire adapter. I have a MBP 2016 running Mojave and the Firewire 800 to USB C adapter and the 400 to 800 adapter. So later today I will give it a try unless you get a definitive answer.
Mind if I ask what software you are going to use and to what purpose? I have three iSight cameras and would like to set up a security system to utilize them ;-)
