works great on 2012 mpb retina and 2012 mba,
Verified Purchase(What's this?)
This review is from: StarTech USB 3.0 to Gigabit Ethernet NIC Network Adapter - USB to RJ45 for 10/100/1000 Network (Personal Computers)
Using the 9/24 dated version of driver 1.2.0 this thing works great on both my mid-2012 mba and 2012 mbp retina, both running 10.8.2
It's comes out of sleep mode a bit quicker than the apple thunderbolt gig adaptor, and it runs at gig speed with no issues. (It did expose an old patch cable as an issue. As soon as I swapped to a genuine cat6 patch cable it worked beautifully. Only 100mbps before the cat6 patch.)
And the leds are a nice touch too.
The driver install requires a reboot - which seems a little 20th century-ish - but that's about the only thing that's not perfect...
