Works if you can find the Thunderbolt 1.2 update
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. …

I have a relatively new Macbook Pro running Mavericks. When I arrive at work and plug in my ethernet adapter, my MacBook crashes. I have a relatively new Macbook Pro running Mavericks. When I arrive at work and plug in my ethernet adapter, my MacBook crashes. It happens probably 7 times out of 10. I have two other colleagues with MacBooks, and the exact same thing happens to them. They have stopped using the adapter as a result. The kernel panic log refers to ethernet code, but there is no solution on the internet and no firmware update that I know of. …
