I am completely new to this so please be gentle.
I have recently Bought a mac mini 2012 running Sierra and along side this a presonus firestudio mobile. I bought the firestudio as it's website claims driver support for osx Sierra.
When plugged in through a firewire 400 to 800 cable the interface powers up but is not recognised at the device bus.
I have tried clearing nvram ect but still no joy.
Hope someone may have a few words of wisdom.
( device is recognised on a friends computer )
