Beginning in 2005, Apple released several computers with a Mini-DVI port, including the 12-inch PowerBook G4, Intel-based iMac, the MacBook Intel-based laptop, the Intel-based Xserve, the 2009 Mac mini, and some late model eMac computers.
The port was used until 2008 when it was replaced with the Mini DisplayPort. This adapter allows a Mac with a Mini-DVI port to be connected to a VGA display.
