Hello, I have a MacPro4,1 upgraded to 5,1 with a Sapphire RX580. Titan Ridge card is installed in slot 3 and working ok. Windows 10 is installed in its own ssd and Mojave is installed in a second one.
Every thunderbolt drive or device showing in Windows in "View Attached Devices" and approved, is showing in Mojave, so far I have tested some TB2 devices from Akitio, ssd tb2, Thunder dock (accepts plug n play in all ports), Thunderquad...
But the main goal is to attach the Pegasus R6 (thunderbolt 2) to this Mac Pro.
In windows, in "Attached Thunderbolt Devices" panel, devices connected hot plug appear immediately and disappear when disconnected, except for de Pegasus R6, Windows is not detecting the pegasus and therefore it can't be seen in Mojave after hot-reboot.
I have tried different Windows versions (1511, 1709, 1809, 1903), both drivers-versions for the Titan Ridge, all driver versions for Pegasus R6 for Windows 10 from Promise site.
The TB2 to TB3 adapter is the one from Apple.
Daisychain won't work with R6.
Any ideas?
