I am looking to upgrade to the Presonus Firepod but only have Thunderbolt 2 on my 2015 Macbook Pro. Originally when buying the computer, I was hoping to get an interface with thunderbolt, but opportunities have risen where I need to upgrade a lot sooner. I tried to get a MOTU 8pre firewire interface. I purchased an Apple Thunderbolt->Firewire 800 adapter, then a 800->400 cable. Unfortunately I could not get interface to interact. Upon further investigation, I found that you need two separate Thunderbolt adapters? This I am unsure of because I've only seen the one Thunderbolt->Firewire 800 available. Before considering testing out the Firepod, does anyone have a working adapter chain that would ensure success? Thanks
