(3 stars) One annoying trait

By: bhaley
This product generally works as expected and I've rarely had any issues except for one that unfortunately crops up daily. I have my MacBook Pro connected to two external monitors but have to disconnect many times a day when I take the laptop to meetings. Upon returning to my desk and reconnecting the dock, the screens may switch (left screen is now the right screen). It happens at least 50% of the time and I have go to my display settings to re-arrange them. I can't isolate what causes it and I think it's just a race situation. Whichever display the dock recognizes first is just assigned a random placement. Frustrating productivity killer.

We're sorry to hear the displays on our TB3DKM2DP are switching when reconnecting the dock. We recommend doing an NVRAM reset because the NVRAM controls how the displays are recognized by the Mac. The instructions for this process can be found here: https://support.apple.com/en-ca/HT204063 . If the NVRAM reset does not help or if you require any assistance, please contact us at www.startech.com/support so that we can help fix this problem for you. Our Technical Advisors are available 24 hours a day, 5 days a week to provide support.

(4 stars) Problems with macOS Mojave and the DisplayPorts

By: wolf773
I bought this dock to use with my 2018 MacBook Pro 15", specifically for the dual DisplayPorts to connect my two 24" ViewSonic monitors. The Monitors work perfectly with my Windows 10 notebook using the DisplayPort to DVI cables. But, I can't get the MacBook to detect either one of the monitors through either DisplayPort on the dock. The USB port, and ethernet port, on the dock work flawlessly. It's definitely fast. I just wish the DisplayPorts worked.

Thank you for your feedback on TB3DKM2DP. We're sorry it hasn't worked for you! This docking station requires active DisplayPort video adapters, so if your existing DisplayPort to DVI cables are passive, no video will appear through them. For an active DisplayPort to DVI adapter, we suggest our DP2DVIS. If you have any questions or need any assistance, please contact our Technical Advisors at www.startech.com/support. We're available 24 hours a day, 5 days a week, to provide support.

(5 stars) Fantastic little travel companion!

By: Nick_147
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: sschramm
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.

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: hubj8569
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. What is Included: 1 - Thunderbolt 3 Dock 1 - Instruction Manual Note: “I received this product in exchange for an unbiased review.”
