Got it, My iPad mini 5 is still with ios 12.3, so I haven't tested this, please try to solve it, Thank you
I tried as iMac 19,1 , “Unable to Connect...time out.” error was fix, but iPad got Black screen. Funny thing is Screen shots still works with both side, Mac and iPad.

What about installation process? Is it easy with this hardware?

The first time I tried, installation process was so smooth.

The second time I reinstalled to another smaller M.2 SSD (Samsung 970 EVO) , always get frozen during installation, but it was completed after retrying several times. Might be something I done wrong, no so sure.

If memory serves me correctly, I reset EFI of the USB installer again, and then finally frozen fixed.

Maybe it's the M.2 SSD caused the problem, I heart the 970 EVO and 970 EVO PLUS may occur the issue.

I heard about 970 EVO+ issue before building hackintosh. The first time I installed Catalina very smooth also 970 EVO (2TB). Freezing problem was after I reinstalled Catalina to 250GB 970 EVO.

Not so sure.

But turn on internal graphics,
(BIOS Version F8)Setting-IO Ports-Internal Graphics-Enabled
will freeze at boot screen.

My samsung 970 evo + needed a firmware upgrade, no problems otherwise :thumbup:
Easily done in windows with Samsung Magician.
