Rated 5 out of 5 by from null Simple enough to plug and go. Only issue is that it doesn't power my Mac as advertised. But it's not an inconvenience to plug in the dock and the Mac charger.

Rated 5 out of 5 by from Not worked as expected - VGA signal produces waves on screen at 1920x1200 @60Hz (with the same cable and monitor that works well with other PC) - Mouse and keyboard disconnects intermittently when external SSD requires bandwith + Power delivery works + Build quality

Rated 5 out of 5 by from Good features - easy install Company provided this for my Mac Pro (2018) and it works well except - the install software will not work on my macOS Mojave 10.14.4. I will still recommend this as a good solution for adding addional monitors to the Mac.

Rated 5 out of 5 by from Set-up nightmare My company bought this for me in addition to 2 monitors and a laptop with a USB-C port. I can’t find step by step installation instructions anywhere. Who can help me out of this nightmare?

Rated 5 out of 5 by from Drivers won't install Work issued this dock for my Macbook Pro running Mojave 10.14.6. When trying to install the drivers I get the message "this driver can't be installed because your version of macOS is too new." So I guess I have a new paperweight?

Rated 5 out of 5 by from Works great after screen roulette finishes No issues when it's working. There doesn't seem to be any rhyme or reason when plugging it in to a Macbook on whether the external monitors will come back in the same rotation or not. Usually flipping the cable over or closing the laptop screen before plugging in will fix it. It's a small annoyance, but otherwise the dock works great.

Rated 5 out of 5 by from Unreliable We bought five (5) of these units to work with Lenovo ThinkPad's. These laptops are equipped with TB3. We've ensured that the TB firmware is up to date on the systems. It does show connected in the Thunderbolt manager (Intel). If you connect a USB, fine, connect a monitor, gamble, connect two monitors, USB stops working. Reboot with a single monitor, USB still isn't working. Unplug USB (camera, USB, keyboard) and reboot with a single monitor, then plug in the USB, 50/50 chance of working. Absolutely unbelievable that a $600 dock is this un-reliable.
