how many external monitor macbook
Apple Products and Services. Most Thunderbolt hubs won't work. In fact, I'm not sure if any will work not. (I've never been in a position to try this with a MacBook Air.) I found several instances from people who thought it would, bought a Thunderbolt hub, then found out it wouldn't work. The best way to do it, is to plug one monitor into the Thunderbolt port and another one into a USB port. To do this you will need the appropriate adapters. What adapters you need depends on what kind of monitors you are hooking up, and what ports they have. According to Apple, you can hook up a total of two external monitors to a MacBook Pro.
