Review on 💻 FebSmart 5X USB-A Ports PCIE USB 3.2 Gen 2 Expansion Card for Windows 7.8, 8.1, 10, Server; MAC OS 10.9.x, 10.10.x, 10.12.x, 10.13.x, 10.14.x, 10.15.x - Self-Powered Technology (FS-A5-Pro) by Alex Cassanova

The card installs easily in my 2020 Mac Pro with version 10.12.6. OSX recognized it straight away and it works as advertised, no software/driver issues or tire jumps. The only issue I had was that the card is too short for the PCI mechanical latch to latch and not secure enough under the Mac card latch which screws onto the top of the card slot's metal shell, so you need to be VERY careful when connecting USB cables or you may disconnect the card.
