Does in fact work with macOS Mojave 10.14.2; just requires manual installation of the driver first
Some previous reviewers from 2018 commented on how this unit doesn't work with a Mac... those issues no longer exist with the latest macOS at the time of this review (10.14.2 Mojave). However, it is NOT simply plug & play like most people might expect.... you need to go to the TrendNet support site for this product and download the driver for macOS. Once I installed that baby I was good to go.... if you do it right you'll see the adapter show up as "AX88179 USB 3.0" in your network settings. I tested this unit out on my Raspberry Pi 3 B and B+ as well... it was plug & play... sounds like the same will be the case with Windows, but I don't have a PC so I haven't tested that. I only have 200Mbps internet so I didn't get to test the full capabilities of this unit - but it certainly performed better than my older model 10/100 adapter from Apple, which of course maxed out around 100Mbps.

Works as needed
Honestly, I can't tell you if it'll live up to the Gig rating, but here's what I can tell you. My old Win 7 relic has a 100M ethernet port, which was bottlenecking. I couldn't get more than 90mbps down even though my internet gateway was pulling in at 700mbps down. Using this adapter, my speeds bumped up to 180, which may not be blazing, but it IS a noticeable improvement. No issues at all with driver install, seems solidly built. Good bang for the buck. Pays to stay with the established and respected brands.

Works Wonders With My Mac and Linux Computers.
I have to say this product works flawlessly with my MacBook Air and Kubuntu (Linux) computer. As the MacBook Air did not have a disc drive I simply went to the TRENDnet website and downloaded the drivers. After downloading I installed the drivers and it worked without any issues on the MacBook Air. I repeated the same process using my Kubuntu (Linux) computer and got the same results. The device works exactly as stated and is able to cross OS platforms without a glitch or problem of any kind. I would definitely recommend this product especially for a newer Apple (Mac) computer as none of them come with a disc drive and most don't even have an ethernet port. I was initially going to purchase the Apple version of this but after reading the reviews and how low it was rated, sprung for this and have not regretted it. Just plug it in to the MacBook Air, attach the ethernet cable which is then connected to the router and within seconds you are connected. Great product and fast shipping.

It works but doesn't show/indicate that it is connected/working.
It works with my Acer Chromebook 15, but it didn't tell/show me that it was connected/working. The reason for 4 stars instead of a 5, is the lack of any paper instructions re using it with an Acer Chromebook 15, and that it works, but doesn't show that it is connected/working. I lucked out and tried to see if I had a ethernet connection. It worked and is very fast. The connection is a simple/easy~plug the ethernet rj45 in the Trendnet connection slot and plug the USB connection into my Acer 3.0 USB port.. However, there is no icon showing that you are connected to the ethernet. I can now use my Acer Chromebook 15 like a desk top. With the above connections, I use a HDMI cable to connect my Chromebook to my new View Sonic 22 " monitor. I also, use a Logitech USB wireless keyboard/mouse. I have incredible HD images on my View Sonic monitor. The Acer Chromebook 15 with this setup is very fast. I can sit back in my easy office chair and do what ever I need to do with the increased security of an ethernet connection versus WiFi with the USB keyboard/mouse on my portable lap desk. Now, I'm in my family room with the ethernet plugged into a TP link in a nearby wall socket and connected to my Acer Chromebook 15, and I used this connection to place an order to Amazon for to use this with my Android Tablet.

Works perfectly on Macbook Air
I have Yosemite on my early 2014 Macbook Air. After installing the most recent downloaded driver, the TRENDnet USB GigE adapter went right online and began working immediately. However, there is one difference between this USB adapter and Apple's Thunderbolt adapter. If you are using multiple network profiles, you will need to load the device onto each profile manually and separately. This is unlike Apple's Thunderbolt GigE adapter which loads across all existing and new profiles automatically. So, for example, if you create a brand new network profile, you'll need to click the + and then choose the TRENDnet adapter to add to the profile. Once added, it lights right up and comes online. How would you know to do this? If the profile doesn't contain the adapter when you plug the adapter into the USB port, it won't light up or activate. I quickly realized that the profile did not have the adapter listed and added it. If there is one thing I would like TRENDnet to change is to automatically load the device into whatever profile is currently active so that the adapter 'just works' like Apple's Thunderbolt adapter. However, the TRENDnet driver does automatically load onto the profile currently active at the time the driver is installed. It just doesn't install into any existing profiles or into any new network profiles you might create. Note that I would have used Apple's Thunderbolt adapter for my needs except that I'm using that port for a second monitor. So, the only choice left is a USB GigE adapter when I use the second monitor. I'm also a little surprised that Apple doesn't offer a USB version of their GigE adapter because of this exact issue. Though, I'm glad that this adapter works as well as it does.

It works well with the Surface 3 Pro
Got this to pair with my Surface 3 Pro to provide a wired connection alternative when WiFi isn't available (or best). It was truly plug-and-play, kind of refreshing. The normal connection when at my desk is through the wired Ethernet port on the docking station. When I tested this the first time, the Surface was still in the docking station. I unplugged the cable from the docking station and plugged it into this adapter. The system connected immediately without any issues even while still in the docking station. As with any USB device, having it connected does shorten battery life, but it's not oppressive. The Surface 3 Pro (now on Windows 10) has pretty decent battery life for such a small machine, and plugging in anything does make a pretty significant difference. Adding this isn't a bad as using an external display with an extended desktop, and there's still more than enough endurance for a 2-hour teleconference with both of those plus a USB hub and video teleconference camera/speakerphone.

Does not work out of the box
I was about to return this as DOA, however when I wanted to put this back I realized there is a CD in it, which has document and drivers, I bought this because I run Redhat workstation and have my own USB3 hub that works as a port replicator, and was using D-Link USB2 adapter which works with Linux out of the box and is OK for internet surfing but not home network file copy. For Windows you just run a setup.exe (I did this first) but for Linux you need to compile the code, and very easy to install. I did some performance testing with another machine which has SSD (same as my laptop) and it was equal or better than Intel Ethernet adapter on my machine. Pretty happy with the price too

Allowed me to restore my wireless Laptop via Server 2012 Essentials
I have a Dell XPS laptop/tablet that gets backed up daily from my home server which runs Server 2012 essentials. I am usually able to do a complete system restore with a bootable USB Drive on all of my other machines, but recently when I tried to restore the XPS - I was unable to connect to the server. (The XPS only has a wireless connection and I was going crazy trying to find different drivers that would work) With this Adapter connected to the 2nd usb port, I booted the XPS into the recovery environment and then used the option to "load drivers" to load the driver which I had copied to another USB drive. I found drivers on the included CD (Drivers > Windows > Win8 Setup > Program Files > TRENDnet,inc >Windows 8 Drivers > 64 bit). I was then able to connect to my server and fully restored the XPS For $15, I am very happy with this solution. I also had a similar problem trying to restore an Intel NUC that has an ethernet port but again, the proper driver is very hard to find. I am sure that I could have easily used this adapter on the NUC also

Not working with Windows 8.1
Not working with Windows 8.1 . The driver is no longer compatible to the OS and no one is interested in fixing it . Neither TRENDnet nor ASIX . TRENDnet has a very bad support they have customer support executives who has no technical knowledge on their products but just work like answering machines

Perfecto para el Nintendo Switch
Funciona con el Nintendo Switch y además el cable tiene la distancia perfecta para conectarlo al usb 3.0 que trae detrás y que el cable quede afuera, tengo una conexión mas estable se nota con el smash bros en linea no va súper perfecto pero si tiene mucho mas fluidez el juego y menos bajones de frames, al parecer tengo que mejorar mi internet ahora.

It works on the Nintendo Switch, and it uses the same chipset as the "official" Nintendo-branded adapter
I bought this for my Nintendo Switch as a cheaper alternative to the semi-official Hori adapter, and I was not disappointed. This adapter uses the exact same chipset and offers the same specs as the Nintendo-branded one for half the price. I have only tested it on the USB 3.0 port on the back of the Switch's dock, but I am getting a gigabit connection and it is working as expected. The cable on the adapter is long enough that it clears the door on the back on the Switch dock when plugged into the rear USB port, so the door is able to close properly. The adapter portion hangs out the side of the dock; it's somewhat visible in my setup, but not a huge deal. My only complaint is that the adapter is only available in white and it would look a lot more discrete if it was black to match the Switch's dock and the other cables. Overall, this is definitely a great alternative to the Nintendo adapter if you're looking to save a few bucks.

Macht genau das, was sie soll
Habe eine kostengünstige 2. Netzwerkkarte für mein OPNSense BOX auf Basis Proxmox gesucht. Passt hervorragend und war schnell einzurichten.
