The Thunderbolt Port is used on MacBook Pro, MacBook Air, Mac Mini and iMac computers from Mid-2011 and later. It is identified by the lightning symbol on the computers and/or cables. The Thunderbolt technology supports high resolution displays and high performance data devices through a single, compact port.
Mini Display Port
The mini-DisplayPort was introduced in October 2008 and is the current Apple standard for laptop computers.
This connector is used in revisions of the MacBook, MacBook Air, and MacBook Pro notebooks, iMac, Mac Mini, and Mac Pro desktops and also the 24-inch/30-inch Apple Cinema Display released since October 2008.
HDMI ports are more common now, and they require a single cable to connect between computers and conference room equipment. The image below shows a HDMI port on a MacBook Pro.
The mini-DVI connector was used in select Apple portable computers between 2003 and 2008 and it is found on the 12-inch PowerBook G4, Intel-based iMac, the MacBook Intel-based laptop, the Intel-based Xserve, and the 2009 Mac mini.
