Hi Everyone,

I have a very stable fresh install of Catalina running. So far everything except Wake from Sleep works.

My unit wakes from sleep except the monitor is a blackscreen. I have tried various darkewake settings with no success.

If anyone has a similar issue and was able to resolve it please help.

Thanks.

Same issue with my setup and RX580 GPU, works perfectly in Mojave, waiting for future release of Catalina :yawn:
 
Can confirm solved.. Disabling serial port in BIOS solved the problem.

The Hackintosh now sleeps better than Windows 10.

Note: I have to push the power button to wake, the mouse/keyboard will not wake machine, but the machine comes back with audio, network, video very fast.

Very happy, thank you for the fix!
