Have connected it to my 13 "MacBook Air with the latest 2014er software version (Yosemite). Subsequently, infected the land cable and immediately ran the Internet. No installation of software needed for the USB 2.0 version.
Processing default makes part also a good impression. How it is looks at long-term test yet to be seen.
For me personally, for 10,99 a strong buy recommendation, since the price of the original adapter almost a joke in my opinion.
