Disable CFG LOCK in your BIOS. if you don’t find that option, then go back to config.plist, check KernelPM at the ‘Kernel and Kexts to Patch’ page.

Ok, in this config, i unchecked KernelPM to get native PM, but you have CFG lock. I added AGDP disable patch, seems that’s a problem for your imac14,2.

You can always go back to the config at post #9

Yea, once I got to the desktop. The monitors lost signal when waking from sleep.

You could try unplug the display cable and plug back.

Is your monitor connected to rx 580 via Displayport or HDMI? Try DisplayPort first.
