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.

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

    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.

  • Randomly disconnects

    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.

It worked the first couple of times I tried it, but since a software update, nothing. It sounds a lot like problems people were having a year or two ago, but I haven't found a solution. I'm really getting tired of buying apple products that are one software update away from not working. I've had a similar problem with Bose speakers and my iPhone. I've been a longtime Apple fan, but this is trying my patience (and my wallet) big time.

    The previous "yes" answer is correct, it does indeed work under Wndows 7 Bootcamp, but the answer is 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,

    The easiest is to purchase a Thunderbolt to HDMI adapter. Apple makes Thunderbolt to VGA and DVI ad The easiest is to purchase a Thunderbolt to HDMI adapter. Apple makes Thunderbolt to VGA and DVI adapters, but for whatever reason has left it to 3rd parties like Belkin, Kanex, StarTech and others to sell (buy it from the Apple store if you are worried about compatibility and return issues).

    If this is your home TV and you simply want to use your Macbook, iPad or iPhone to display on the TV look at buying an Apple TV. It is the only Apple product with built in HDMI that will easily connect to to your TV or other HDMI device. You can then use Apple's AirPlay feature from any recent iPhone, iPad or Mac to mirror the desktop to the TV. Very cool feature and better than dragging cords around.
