The microphone is really class. Crystal-clear sound, zero noise or noise. I had previously a Samson G-Track USB microphone that had but returned due to the clearly audible background noise again and then decided on the Yeti - this was spot on. Super microphone, great processed, what more could you want. Unbeatable for the price.
I use it on the MacBook Pro, OS X, Yosemite, Logic Pro X 10.0.7 - no drivers needed, just plug it in USB port and running!
