    This adapter requires an update to the AppleBCM5701Ethernet plugin to work. That update was present in the thunderbolt software u This adapter requires an update to the AppleBCM5701Ethernet plugin to work. That update was present in the thunderbolt software update 1.2 package. Said update was pulled from the automatic update list due to it crashing non-thunderbolt systems such as old macbook pros. I haven't read a report of any problems for us macbook air users, and it works great on my 2011 macbook air. If you're lucky enough to have grabbed a copy of the update from apple's KB article before it was pulled from there as well, you should be able to use the adapter. Presumably apple will fix this big error in a day or so with a newer thunderbolt update.

    If you know what you're doing, you could always backup your IONetworkingFamily kext before applying the update, and then restore just that kext it if your system crashes from the update.

    Nice performance with this dongle - I get 900Mbps throughput. Driver (and broadcom's specs) indicate jumbo frame support, but I haven't tried it. Jumbo frames not really necessary IMO since the CPU is beefy enough to handle high packet/second data rates.

    Finally a cheap way to get data on&off a macbook air at speeds above USB 2.

  • Excellent product but a bit pricey

    Having read some of the reviews of having to upgrade the Thunderbolt driver, I was initially put off. But bought it on a sale-or-r Having read some of the reviews of having to upgrade the Thunderbolt driver, I was initially put off. But bought it on a sale-or-return basis to try it out. Have been working with it for a few hours now on my mid 2011 MBA running OSX 10.8.5. There are no problems. The speed is very good when compared to the wi-fi option. I use Tor and TorBirdy and sometimes use the Tor bridge which really slows down the communication traffic. With a direct connection to the ethernet through Thunderbolt the speeds are much enhanced now.

    I have plugged it into the LAN port of Airport Time Capsule. Have also tried it through the LAN port of the router. It works fine on both machines.

    It is however a bit pricey and there are no cheaper 3rd party choices either. I also had to buy a 5m cable to reach the router from my desk which was another expense I had to add to the price of the adapter.

  • Works perfectly with rMBP w/ Boot Camp Win 8.1 & OS X Yosemite

    5.0 out of 5 stars

    This adapter is well worth the money, and it works beautifully. I am using it with a Boot Camp version of Windows 8.1 and OS X Yos This adapter is well worth the money, and it works beautifully. I am using it with a Boot Camp version of Windows 8.1 and OS X Yosemite. It supports sleep mode on both operating systems, contrary to what some people are claiming here. I am guessing this is because of new drivers released around August 2014 for Windows 8.1.

    Only con is that it is not hot pluggable with Boot Camp Windows 8.1 started. If you unplug it, you have to shut down Windows and restart it with the adapter plugged in. OS X supports this! For now, if you want to hot plug an Ethernet-adapter in Boot Camp Windows installations, you need to buy a 3rd party USB3 Ethernet adapter. I don't find it flimsy either, as some people here are stating. It fits snugly in the port.

    I bought this to be able to backup 1 TB of data a bit quicker. So far it's not working, as it always looses its connection before I bought this to be able to backup 1 TB of data a bit quicker. So far it's not working, as it always looses its connection before the backup completes, making the backup fail. Not very impressive. No status light either, so you can't tell by looking at it if it's working or not - you have to pull up Network Preference and see if it's green. Plugging it in and out works, sometimes, but this thing is a pain in the rear. My 6 year old macbook's built in ethernet is far more reliable.
