Apple Mac users - The new USB-C port requires USB-C Digital AV Multiport Adapter to connect to an external projector with HDMI. Unfortunately this connection is not predictable! Too often there is no synchronization with the projector - Any kind of projector. No image!!! This happens not only to me, but to many of my colleagues who have been trying to present with their new MacBooks. Until Apple solves this BIG problem - if you intend to present with your laptop - stay away from Apple's new MacBook Pro.
