I own a Studiolive 32.4.2 AI mixer used as the primary interface for sounds getting into and out of my imac in my recording studio. It connects to an imac currently running 10.8.x but will eventually upgrade to El Capitan. As firewire support and ports start to disappear from Apple products, will Presonus roll out a hardware card to support thunderbolt or usb 3 when using the mixer as an audio interface?
