Tera Grand Mini DisplayPort to HDMI Adapter lets you connect Apple MacBook, MacBook Pro, MacBook Air, or iMac to HDTV or any HDMI display. You can use an external display as your main workspace or to extend your desktop, or you can work in mirrored mode with a projector so you can view what your audience sees.

iMac Model 11.2, 11.3 (Mid 2010) and later
Mac Pro Model 5.1 (Mid 2010) and later

** For MacBook Pro (Mid 2012) and MacBook Air (Mid 2012) users:
Please download the software update: "MacBook Pro (Mid 2012) Software Update 1.0" , "MacBook Air (Mid 2012) Software Update 1.0" from Apple Support web site. (Due to Amazon's policy, we are not allowed to display the link here.) These updates fix external display support.
Apple Mac computers made before 2010 do not support audio over Mini DisplayPort. You won't get audio from the Mini DisplayPort to HDMI adapter, only video signal.
This Mini DisplayPort to HDMI Adapter is also compatible with other non-Apple notebooks with Mini DisplayPort, such as Microsoft Surface Pro for Windows 8 Pro, HP Envy 14/17, Dell XPS 14/15/17, Lenovo ThinkPad notebooks with Mini DisplayPort.
