I ordered the OWC Thunderbolt 3 Ethernet to connect my Macbook Pro to the Ugreen NAS. The Macbook supports Thunderbolt 4 but the NAS tops out at 10gb. Spending $150 more for a TB4 adapter would have been pointless. The OWC Thunderbolt 3 adapter works great. I have no problem using the NAS editing 4K/60 Premiere Pro projects. The adapter does get warm to hot. This seems to be the nature of 10gb ethernet adapters. They all have massive heat sinks. So far it's working really well. I'll update the review should my experience change after a month or two of heavy use.

These are not reliable devices, at least on macos. The connection drops to 100mb equivalent without warning, and requires cycling the connection, or recreating the network interface to go back to 10gb. Runs very hot. Also, no linux support. Go with the sonnet. It's reliable, smaller, runs cooler, and linux support is seamless.

At first I was stymied with lower speeds than even a simple gigabit USB-c adapter with this device. It turns out that you need to turn off AVB/EAB mode in Mac OS advanced network settings to get this to work correctly. The AVB/EAB mode is some non-standard thing for streaming audio from network connected keyboards and such that is not used on any normal ethernet network at all but it causes the adapter to significantly underperform. I get 10 gigabit speeds only when turning this off. This turns out to be a known Mac OS issue.

I have a new Mac Pro 2020 tower. Since I use both Mac OS & Windoze professionally, I set it up with 2 bootable drives. Of course the Mac OS runs perfect out of the gate... But, when I got Windoze 10 Pro bootable from an external drive, I found that Windoze can't see the ethernet, because it wan'ts drivers for the cards. I am still waiting for the Apple support team to get me the info so I can update the drivers. But in the meantime I bought this, and the site had a link to the drivers! Its awesome! Download speed is on par withe the native Mac OS speeds, around 550 - 750mps. My only complaint, is the upload speed seems throttled? I get high speed download, but upload is around 15.5mps. When booted to the Mac OS, using the internal ethernet, I get FASTER upload speed than download! Around 850mps!!! (Update, this is confirmed a Windoze issue!) All in all, totally worth the price! I read some thought this was expensive? Hell, for the speeds I am getting, it is worth every penny!

Just works perfectly with my Mac! Easy to use.

The Good * Fast * Easy to set up * OWC support is phenomenal The Bad * Unreliable * Gets hot, shuts off? * Huge heatsink but no/ineffecfive fan? * Required to work with OWC support if not satisfied The Ugly This took a reboot to show up in my M1 Mini, and is blazing fast. Pretty quiet, too. Thing is a monstrous size. Problems came quick, though, and I suspected issues with the thunderbolt cable, swapping with others I had in the house. I decided to return/replace, and Amazon required I work with OWC if not 100% happy, instead of just returning. OWC support is great, but all the ideas and addons weren't going to get around the fact that the heatsink-case was getting upwards of 60°C to the touch, and the device is just entirely too unstable to be of use. I ended up going with a Sonnet SFP+ adapter that runs far cooler and equally as fast. Great attempt, but 10GbE is too serious business to go half in.

I decided to upgrade my home network and bought this adapter to use on an M1 Mac Mini. The product itself works great, gives me fast transfers and barely even gets warm no matter how much I use it. However, I ordered and paid for a NEW product and "fullfilled by Amazon" sent me one that appeared to have been previously opened/used. When I opened the product box, this adapter sat on top of the plastic bag that it should have been inside of. Either OWC's quality control missed this or I got a used product. Since I never had a problem with the device, I let the return window close and just continued using it. At this point, I have had the adapter for several months and have been very happy with its performance. Hopefully, this review was helpful to you.

Unlike another similar looking product for thunderbolt 10g, this one from OWC worked great out of the box. but do remember to download the driver from their website first! Getting pretty consistent speeds of 8g. Awesome.

Ich verwende den OWC Thunderbolt Adapter mit meiner Synology NAS, um eine 10-Gigabit-Verbindung herzustellen. Auf meinem Mac läuft aktuell macOS Sequoia Der Adapter wird sofort erkannt und liefert eine zuverlässige, stabile Verbindung. Man muss nur die IP Adressen direkt vom Synology Nas und vom Mac zuweisen um die 10 Gbit/s zu erhalten. Voraussetzung Das Synology Nas hat den 10 Gbit/s Anschluss. Für alle, die eine schnelle, problemlose Lösung mit Thunderbolt suchen — insbesondere auf neuesten macOS-Versionen wie Sequoia — ist dieser Adapter eine klare Empfehlung.

Super rápido. Não existe palavras descrever. Funciona como esperado.

This gave my Macbook Pro a stable 10GB/s LAN connection. Ideal for video editing directly on a NAS 4k real time scrubbing with no sweat in Final Cut Pro.

Solo il driver altrimenti non funziona piu
