Good Morning Everyone- I currently have a MacBook Air (Mid-2013, MacBookAir6,2) running 10.12.1. I'd like to hook up a 2nd external display to it. I currently have one external monitor working well using Amazon's Thunderbolt to HDMI adapter. I understand that in order to get a 2nd monitor hooked up, I'd need to use a USB to HDMI or DVI adapter as well. I've looked on Amazon for a bit and see mixed reviews on many devices. In the answered questions section, I've seen people saying a lot of these devices do not work with mac while the next answer for that very same product, someone states that it does. Before I purchase one I'd like to get the advice of any users on here that have a USB to HDMI or USB to DVI/VGA adapter that does work with their MacBook Air. Please let me know. Thank you very much everyone .
