Hello, I have the Sapphire radeon RX 460, following the installation of High Sierra, I can not boot the OS, after the command line has finished initializing OS X, I fall on a black screen or there is no display.

Yet with the AMD sapphire radeon 6870 I can start Mac without much problem!

Sorry for my bad english :/

Following several research, it is necessary to activate its IGPU and put it in primary, but I have an AMD-FX processor which does not have IGPU!

Do I have to completely change my graphics card?
