For me I think the Thunderbolt to Gigabit Ethernet Adaptor was probably the most exciting thing to come out of WWDC. After I got my 2011 Air I’ve been waiting for someone to sell one of these.
I ordered the $35 adaptor from the Apple online store right after the keynote, it mades it’s way to Perth from Sydney over night and I was quite excited when I saw that it had arrived. I opened up the packaging and plugged it into my Air, opened up the networking preference pane, to find nothing… The new interface wasn’t listed, I ran ifconfig, wasn’t there either. I then remembered about reading this article, doh.
So after waiting a week for Apple to re-release the update, I was finally able to use my new adaptor. I did some speed tests using the AJA System Test, from a SAN to my Air, I was able to pull down 46.5MB/s and upload at 45.7MB/s, as seen in the screenshot below.
The Thunderbolt to Gigabit Ethernet adaptor is available on the Apple Online Store for $35 with free shipping and is supported by any Mac with a Thunderbolt port.
