Support by Apple devices
The only portable Mac models to directly include an HDMI port were the 15 and 13-inch MacBook Pros with Retina display, introduced in 2012 and 2013, respectively. All other models since then require a USB-C Digital AV Multiport Adapter or a 3rd-party Mini DisplayPort to HDMI adapter or cable. Among desktop models, the Mac Mini has included HDMI support since the thinner aluminum form factor was introduced with its 3rd generation update in 2010.
