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. …

Save your money
I bought this shortly after they came out but just got around to running an ethernet cable to my desk in mid February. I was happy I bought this shortly after they came out but just got around to running an ethernet cable to my desk in mid February. I was happy to have a wired connection to my Air finally but today I noticed a marked decrease in performance. After logging out, then restarting with no improvement, I checked the network to find I was on Airport. The Preference Pane said the cable was unplugged, but it wasn't. The adapter was significantly warm to the touch and unplugging and plugging it back in did not help. System Profile could see it but it just quit working, giving me a very short useable life; less than two months. …

Draws more power than Wi-Fi
I bought this adapter for my new, late 2013 MacBook Pro. The adapter itself work great. However, I purchased it thinking it will d I bought this adapter for my new, late 2013 MacBook Pro. The adapter itself work great. However, I purchased it thinking it will draw less power than Wi-Fi does, so I save on battery power. NOT TRUE! Turns out, this little think draws more power than using Wi-Fi. I had not anticipated this and so I didn't search on this before I purchased it. But it turns out, other also complain that it draws more power than Wi-Fi.
So if you plan to use the adapter while the laptop is running off the charger, then it's great. But when running off just the battery, it's better if you stick to Wi-Fi, if you have a good connection. I will be returning the adapter. …

The Mac Book Pro Retina laptop just silently added it in the background. I went into my system to check to be sure it added it and it was there.
No pop-up and easy to use.
I am very satisfied as I always am with Apple products and service. …
