I am running
I have all of the Thunderbolt settings enabled on my Gigabyte motherboard.
MacOS High Sierra
PreSonus Quantum
i7-8700k
I have the Gigabyte Alpine Ridge Thunderbolt 3 card out of the PCI-e x4 slot. The indicator light next to the thunderbolt logo is flashing on the Quantum, but it wont come up in either Universal Control or in Studio One.
