    Hi,

    I am running Mojave on a Mac Pro 5,1 with a Radeon 580 card.

    When I install Opencore I get a strange multicolored and washed out boot screen (hello Andy Warhol style !) instead of a standard grey boot with black details screen.

    This is very disconcerting and it’s hard to even make out the various drives to choose from.  I have tried re-seating the card and double checked the cable connections, but it is repeatable and as soon as Opencore hits the startup page, everything goes to normal.

    What is going on ?  Is there any way to correct this ?

    Cheers, C
