Works most of the time. First, my Macbook Air won't boot when plugged into the power port and the power adapter is plugged into a hub. If I unplug it and wait, I can plug the hub back in and it works fine. Also note that this hub gets quite hot when using HDMI and other USB devices. UPDATE 30.8. The seller responded quickly to my concerns and offered a fair and helpful solution. This product will continue to work. I'm just watching how many hard drives, monitors I connect to it. Many Thanks.
