Installed the new Driver / Thunderbolt 1.2 Update from Software Update, plugged it in, and zoom. Works great, no longer wasting a USB port, and its super fast! Will be perfect in those hotels with no WiFi. No compatibility issues with my 2011 MBA 13 inch I bought last year.

Works if you can find the Thunderbolt 1.2 update
- Written by Bruce C from Kentfield
- 14/06/2012
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. …More

Will Windows 7 (bootcamp) recognize a thunderbolt ethernet adapter?

The previous "yes" answer is correct, it does indeed work under Wndows 7 Bootcamp, but the answer is a bit light on detail for a couple of the steps. Here's a fuller explanation:

1) download the driver per the instructions in the previous answer
2) unzip the drivers to a temporary folder on your hard drive
3) connect the adaptor to the thunderbolt port
4) reboot Windows

Windows should automatically detect the adaptor now and install it. You may need to point the installer at the location where you unzipped the drivers.

If Windows doesn't automatically install the device...

1) go to Start > Control Panel > Hardware & Sound and open Device Manager
2) click the name of your computer at the top of the device tree
3) click Action at the top of the window and choose Add Legacy Hardware
4) Click Next
5) Select "Install hardware that I manually select..."
6) Choose Network Adaptors
7) Choose "Have Disk"
8) Browse to the location of the drivers you unzipped earlier.
9) Click the .inf file
10) Select Broadcom NetXtreme Gigabit Ethernet from the list of drivers available
11) OK and install

You may need to reboot again with the adaptor plugged into the Thunderbolt port to finish the job, …More
