    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 now had three all of which have failed. Yes, apple replaced one free, but none should need replacing. No moving parts. Just I have now had three all of which have failed. Yes, apple replaced one free, but none should need replacing. No moving parts. Just fail after fail. Unimpressive from such a normally reliable company.

    Apple broke this functionality in Yosemite and has refused to add it back in subsequent updates. They really should pay us all ba Apple broke this functionality in Yosemite and has refused to add it back in subsequent updates. They really should pay us all back for the $30 wasted on this crud. This is the first Apple component that ever made me consider that I should give up on the company.

  • Tbolt to Gigabit adapter not compatible w cable modem

    Apple: please address! TWC is my ISP, I use a NetGear C3000 cable modem/router. My MacBook Pro is 4 weeks old. Wifi works lightnin Apple: please address! TWC is my ISP, I use a NetGear C3000 cable modem/router. My MacBook Pro is 4 weeks old. Wifi works lightning fast. However, when I use an ethernet cable and the Tbolt to Gigabit adapter, content takes forever to load, and after three or four pages, won't load at all. MBP detects the ethernet conn and shows it's connected, but I can't browse. Apple, NetGear, and TWC all unable to solve.
