Canon 550D connecting to MacBook Pro via FireWire 800
As far as I know, my MacBook Pro (MacBookPro8,1) has a FireWire 800 port. My Canon 550D / Rebel T2i has a combined A/V output and a mini HDMI port. I've been looking around online about a cable that would allow me to connect these 2 together via Firewire (required by Adobe OnLocation). I'm asking here because I'm assuming that someone here is bound to know something about compatible FireWire cables for my MacBook and my DSLR in order to use the software. My knowledge goes as far as needing to know if the MacBook and the DSLR ports are 4-pin or 6-pin. I don't know how to tell and I can't find this information about my MacBook Pro.
So, the question is: how can you tell how many pins my MacBook's FireWire port requires? And if someone can confirm, is it possible to connect these two things?
MacBook Pro, Mac OS X (10.7.3)
