Mojave was the OS when I bought that thing and other units. I was hopeful since I was having this issue over USB 2 on my 2010 iMac and now I had TB3/USB-C ports.Michael Canavan wrote: ↑Wed Aug 03, 2022 7:31 pm Good luck Mike, all I know is the Sandisk USB-C drive wouldn't work hooked to a USB3 7 port dock, an OWC Thunderbolt 3 dock etc. but now it does. Again, it's fine on Mojave on the Mac Pro with a Sonnet USB3 PCIe card installed, well, except for the whole not showing up at start, unplug and plug back in thing..
My iMac Pro has a Mojave boot drive in the TB2 dock so I can test both ways with a SATA III SSD in a 3.1 drive dock into that hub. This will be interesting.
