Bought 2011 Yosemite the USB micro for the Mac Mini. The Micro was recognized immediately and requires no driver installation and works great. The audio quality is best when the distance to the mouth is 20-30 cm. Further away you have to reckon with some reverb (just as you would from a hands-free function of iPhone / telephone is used) but this is absolutely Okay. The microphone is predominantly at me for calling the Mac and for the dictation of texts used. The USB cable is about 1.20 meters long. A small gripe, there are also. In the micro-a blue LED is integrated, these I find are too bright and she even blinks continuously when the micro receives. If the micro is at rest it lights up continuously. Conclusion: For less than 10 euros you do nothing wrong. The audio quality is roughly in the direction of "webcam" to classify. Class it. Without problems or hanky on Mac work, although that is not listed in the product description
