I have the Pegasus3 with the Thunderbolt 3 ports.
I’ve been using it for about a year connected to a Mac mini with the thunderbolt 3 cable.
Recently the Mac mini died and won’t start up at all.
I want to be able to connect the Pegasus3 to an older Mac with USB port.
I have purchased the Apple brand cable adapter “Thunderbolt 3 to USB”.
I hooked it up to the USB Mac but I get no response from the Promise unit.
The Mac is running 10.13.6 High Sierra.
Is it possible to make this work?
