If you are installing a Sapphire 7950 card into a Mac Pro tower for use with OS X or macOS, be sure to set the Mac EFI Firmware switch to the proper setting before using the card. See the image below for reference. If you're having trouble with the switch, please contact MacSales.com Technical Support. If you would like more information on this process please reference pages 9 and 10 on the Sapphire User Guide.
