![DELL WD15 Monitor Dock 4K with 180W Adapter, USB-C, (450-AEUO, 7FJ4J, 4W2HW) (Renewed)']](https://images-na.ssl-images-amazon.com/images/I/619nHdPyxtL._AC_UL160_SR160,160_.jpg)
I tested this with a new 15" MacBook Pro (late 2016) with TouchBar, running macOS Sierra 10.12.1 as factory installed. I had little confidence in Dell from prior experience and from other reviews here, but I have to say that this product worked wonderfully without any drivers required, and has a great form factor. Below I give details of the function of each port without drivers, and then after installing DisplayLink drivers.
* Gigabit Ethernet:
After plugging in, shows up as "USB 10/100/1000 LAN" in network devices. I tested throughput in both directions using iPerf and confirmed full gigabit performance. I burned it in during all tests to see if warm-up would cause speed loss, but throughput remained constant at gigabit speeds.
* USB3:
Tested performance with external SSD, and compared throughput to direct connection to computer. All speeds the same and at USB3 throughput.
* VGA:
Worked upon connection, tested to 1600 x 1200 at 60Hz.
* HDMI:
Video worked upon connection, tested to 1920 x 1080 at 60Hz. However audio over HDMI did not work (on a cable that I separately confirmed passed audio).
At this point I had everything I wanted, but I decided to try installing the latest DisplayLink drivers from their web site to see if it would fix the audio over HDMI problem (I read that audio is passed over DisplayPort protocol). Installed version 3.0 Beta 1 (1 Dec 2016) and indeed it fixed the audio problem. I note that the driver package also comes with an uninstaller.
I wanted a small adapter I can carry with my small computer case and have quick access to these 4 specific ports I encounter daily going to different rooms, different sites, and to secure or underground locations which have wired ethernet only. This adapter fits the bill perfectly. I did not experience any of the problems some other reviewers mentioned about the order of connections making a difference. Note that when you install DisplayLink drivers, it will also silently update firmware on the adapter itself if out of date. On mine I looked before and after with System Information and saw no differences, but for users here with earlier firmware versions, this might explain some of the observations others have seen with driver interactions. In conclusion, for this system, if you don't want to install any drivers, you will get all 4 ports working with communication and video. If you additionally need audio over HDMI, the driver fixes it.
It is pretty ironic this Dell adapter works nearly flawlessly with a Mac that was just released, and can't even work on Dell computers that have been around for some time. But I'll take it!
-----Update March 2019-----
Still working and works great on 2018 15" MacBook Pro too.
