Troubleshooting erratic problems is a real joy. It depends on the computer, cable and environment working perfectly. Yertis have no natural way to reject electrical interference that the higher end microphones do. That turns the Yeti and cable into an antenna for any electrical interference in the house. I think in some of those instances, the cable didn't make good contact when you plugged it in. I would start with changing out the USB cable. You use your Air portable all the time, right, taking it to lunch and to meetings and later, settle down, plug in the Yeti and record. It sounds like electrical interference from a bad motor, noisy air conditioner, bad lamp dimmer, something like that. There is a 'normal' failure for this and we can try those solutions, but that doesn't appear like normal data failures.
