      Exceptional with the 2011 Macbook Air 13

      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! 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

      This adapter requires an update to the AppleBCM5701Ethernet plugin to work. That update was present in the thunderbolt software update 1.2 package. Said updat 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.

      Unable to use in a MacBookPro late 2013

      An adapter manufactured by Apple *should* work without hours of googling. Mine is still not working. Thanks El Capitan!

      Constantly drops and slow to connect

      Drops irregularly and is slow to connect. Would much rather prefer an ethernet port.
