Worked like a charm. For my use case, I'm passing through the entire PCI device to my VM. The device has a keyboard, mouse, and some other items. These are being passed through seamlessly to a VM. (I also pass through a desktop-class GPU, so that I can use a VM as a "desktop"). Not a moment's trouble so far. ### ⭐⭐⭐⭐⭐ Works perfectly in a 2010 Mac Pro without drivers *by L***E on January 27, 2020* No drivers necessary in High Sierra. No issues with cables properly seating. The plugs on the card do sit low on the back of the machine, but the USB-C connector does not need to be pushed into the point were plastic meets the card. As you can see in my image it appears the cable is not properly seated. Not to worry this is as far as it goes in. ### ⭐⭐⭐⭐⭐ Along with the SSD, this card is one of the best Upgrades to the Classic Mac Pro *by I***N on July 29, 2018* After researching various USB-C PCIe cards I settled on the one from Sonnet because it had good reviews. While cost is important and this was not the cheapest one, my time is worth something and I hate hassles and dealing with computer problems, just want it to work and not have to troubleshoot problems. Followed the instruction sheet and went to the SonnetTech web site to check if there was a more recent instruction sheet and there was. The only difference that I found was the drivers didn't have to be downloaded for High Sierra so that was nice.This went in to my Mac Pro 2012 5,1 and was the easiest installation of anything that I've installed in it. The computer sits on my desk to get it away from sucking in any dust from the floor. Got a small Phillips screwdriver to remove the two screws holding the cards in. After removing the side panel it took all of about five minutes. to remove the empty card bay plate and insert the new USB-C card, re-install the plate with the two screws, and replace the side cover. What could be easier?Turned the 5,1 on, checked "About this Mac", System Report, and it showed that the USB-C card was installed. One may have to drag the window bar down a bit to see the list of all the USB items.Exited About this Mac then connected a 5TB USB-3.0 desktop HDD to the USB-C PCIe card via a 3-foot long Amazon USB-C > USB3 Gen2 cable (this was an Amazon cable). Proceeded to copy a number of video files from the computer SSD to the desktop drive and couldn't believe how fast it went! I was blown over. The first file would have taken "about an hour" via USB 2.0 but with the new card it took only five and a half minutes. Transfer rate for four different large (~45GB) video files was uniform at 137MB/s + or - a MB vs the ~10 > 15MB/s for 2.0. Really impressive. With 4K video files filling up my drives I've got plans for another desktop HDD and this card will be crucial to having a fast workflow and an improved backup system. ## Frequently Bought Together - Sonnet Allegro USB 3.1, Two-Port USB-C 10Gb PCIe Card (USB3C-2PM-E) - SAMSUNG 990 PRO SSD NVMe M.2 PCIe Gen4, M.2 2280 Internal Solid State Hard Drive, Seq.
