No, I have a Sapphire PULSE Radeon RX 560 14CU 4GB GDDR5 PCI-E HDMI / DVI-D / DP OC Version (UEFI) - didn't have the $$ for 580.

In your Bios enable multi monitor support, PEG/PCIE(RX 580) as primary, IGPU enabled DVMT pre allocated memory 128mb.

Hi Matty. I really need you help again. I finally upgrade to Catalina 3 days ago and the install went fine and 10.15.7 is running just fine on my coffee lake with RX560. But when I ran the security update 006 it will not install and i now have the install disk on the clover start page as a third choice. I have posted "

Catalina security update 006 went south" on the Catalina Desktop Support but have not gotten any response​

Thanks for your help, Jim

Well, updated my Z370XP SLI to F15 due to the warning that there was a security vulnerability. Didn't know about this until I did it. I've tried adding the patch to the installer USB but still will not boot. Any advice?

I have HS with clover 4.4.5.8 working.. My MB is aorus z370 gaming 7 with F4 BIOS. I've added the patch... Do you think if I update the bios from F4 to F14 will my hack boot without any issues from Clover or High Sierra? Is it enough to just patch the clover and update the bios?

F14, not F15, cause there is no way back from F15...

Your system is comparable to my second system. I am also using the same Clover version 4458 to boot MacOS High Sierra 10.13.6 (and also Sierra 10.12.6) on my system.

From my own experience, if you added the patch to config.plist correctly, then after upgrading the BIOS and configuring the BIOS settings correctly, you should be able to boot back into High Sierra.

Update: moved to OpenCore. F15 now works fine without any patching.
