    I have MacPro 4.1, and my gt120 is not working (black screen) (it looks like capacitors leaked - maybe I can replace them...) I have RX590 (without efi bios) Can somebody provide me an opencore usb image? So I can try to boot with rx590? (and flash to 5.1) Thank you

    I am fairly new to the cMP scene and have been considering upgrading my mostly stock machine. I'd love to be able to set up Catalina with all the bells and whistles via OpenCore as shown here, but am not experienced enough with OpenCore and cMPs in general to figure it out myself. Thanks, CL
