Finally.
I made mobo and GPU works for latest macOS Catalina without any issue.
I have been spending lots of time, non-sleep and keep reading and studying.
Lots of tested, wasted lots of time.

Finally, it succeeded.

If that's the only problem then all that you need to do is delete the /EFI folder on the EFI partition of the SSD, then copy the /EFI folder form the EFI partition of the USB to the EFI partition of the SSD.

Hi, succeeded to make this Mobo works with Catalina now.
I did NOT replace EFI from USB as your mentioned, cause it won't works too.

Reading the Clover and boot loader needs, eyes must focus on all wording and testing many times.
Really tired and wasted lots of time.
Now it works.

But USB 3.0 not working at Catalina.
You know what is the problem?

Will try to reading this post. If I cannot get it. Will ask from help.

My RX580 GPU fans will stop spinning after access to Catalina desktop, and even for High Sierra.
IS your GPU also? I saw your profile is RX560.

Just wondering is this GPU condition is normal.
As others told that it's normal, due to not over 55-degree-C.

If you have more than one HDMI port then try another.


I have no idea why it's not working for you unless you have one of those dodgy Chinese cards that use a different device ID.

Your GPU typically should have at least 2-4 HDMI ports on the back. If you are having problems, try using the one next to it as some AMD GPUs have this issue on bootup on macOS.
