StarTech.com Thunderbolt 3 to 10GBase-T Ethernet Adapter - Multi Gigabit Network Adapter - USB Type C Connector (TB310G)

Please do not buy this if you own a Mac M1 or above model, will not work even if you try as hard as you can to make it work.This driver is compatible only with Intel-based Macs. Apple Silicon Macs (e.g. M1-based Macs) are not supported.

This is a great device that, if you're on a Mac, uses the built-in drivers (a huge bonus) with nothing else to install. Performance is excellent. Gets a bit warm, but that's not a big deal on a desktop. One issue that applies to any device using this Aquantia ethernet chipset is that macOS does not support Airplay streaming over these devices. It's a bug, and unknown if it will ever be fixed by Apple. So if you're relying on Airplay over ethernet, you'll need to use a different dongle (a non-10GbE or non-Aquantia chipset). Otherwise, this is a solid buy.

Lack of drivers for most recent versions of Mac OSX. Their site indicated to go to another vendor for drivers - which didn't work either.BOTTOMLINE - unless you want to step a few years backward for compatibility with this adapter, buy somethin else. I purchased OWCs Thunderbolt 3 to 10G Ethernet adapter and it works just fine with both lastest OSX and Windows.

Needs drivers for Mac. Last driver was for Mac OSX 10.14 Mojave. No driver since. Now it's an expensive metal brick doing nothing. Nothing from StarTech about new drivers. Don't buy

This one needs Tehuti drivers for Mac running HS 10.13.6, so it’s not plug-and-play. When connected (after much ado), it constantly causes network connectivity to be lost for all hosts on the network that uses an Asus ROG AX11000 router and Netgear Multi-Gig switches XS-512EM and (further down) GS-110EMX – as in unplug the TB3 cable and network connectivity is restored for everyone. I’d recommend one for which the Mac has built-in drivers.

パソコンメーカーさんとStarTechテクニカルサポートさんと色々やり取りしたのですが、どう設定しても10Gの本来のスピードにならず出ても1G〜2Gちょっとのスピードしか出なく困っています。ランプもグリーンのまま返品したい気分です。

dellパソコンで使用していますが速いです。国内メーカーを探したんですがみあたらず、star techさん出してて良かった。長時間使用すると本体が熱くなるので涼しい部屋で使った方が良いかも。
