(5 stars) Fantastic little travel companion!

By:
Keep in mind, that this is TB-3. This is *NOT* TB-2 or USB-C. OK, the negative first: The built-in cable is WAY too short and not removable. Now to the good stuff! This thing is FAST. It just worked on my Macbook. Even driving dual-4k, transferring data via USB, and network, nothing seemed to slow down at all. It took some dings in my field bag, and got some dust and fuzz in there, but it never stopped working. Keep some of that "non-slide" shelf-liner with you and this little lightweight dock won't slide around either (being that light is a plus in my book!) I received this product in exchange for an unbiased review.

(4 stars) Almost fully works with Mac

By:
I was able to connect two 4K monitors and run both at 60hz on a 15" 2016 MBP via Thunderbolt 3. The USB port works but I was not able to get the Ethernet to work. I checked the downloads section and could not find a driver.

Response from StarTech.com:
Sam, Customer Support
Thank you for your review of TB3DKM2DP. We're sorry it hasn't fully worked for you yet. The Ethernet port on this dock is natively supported in macOS. Since it's not working for you, you may need to add the Thunderbolt Ethernet interface under "System Preferences" > "Network". If you need any further help, we encourage you to reach out to our Technical Advisors at 1-800-265-1844 or www.startech.com/chat. We're available 24 hours a day, 5 days a week, to provide support.

(5 stars) Excellent 4K Monitor Mini Thunderbolt 3 Dock

By:
I have been in the AV/IT Integration space for over 30 years. I found this unit easy to setup and use on my Microsoft and Apple devices. This unit is bus-powered, so there is no external power required, which is a great feature. The attached USB-C cable has an extended length of approximately 8 inches, which allows for flexibility in physical set up. The unit installs quickly and is compatible with a variety of operating systems, which I tested.
