Never say "never".There is NO way to add thunderbolt to cMP.
Never say "never".
One could toss the Apple motherboard and adapt one of the third-party T-Bolt capable Intel mobos on the market to fit inside the cMP chassis. (Some metal-working might be needed.)
I am going to start using a thunderbolt device but I don't know anything about it. I am assuming I can use a USB 2 to thunderbolt adaptor?? I have two cMP mid 2010 (2.66 and 2.8) converted to 3.46. Will this work?
Hm. I've talked to several people who have been successfully been using a FireWire to thunderbolt adaptor.
They are connecting a Thunderbolt device to a Firewire port on the computer? That doesn't seem possible.
