[Solved] Fail on Mojave upgrade GA-270N-WIFI stuck need help!

[asleb]

Hello,
My build:
- GA-H270N-WIFI
- Intel i7 7700K
- MSI Radeon RX560 8GB
- Samsung EVO 960 500GB M.2 ssd

I had a fine running system with OS X 10.13.6. Then I tried to upgrade directly. After first reboot I got a white screen with Apple logo. Nothing more. I thought I had prepared my EFI folder properly before the update, update clover boot loader, update kexts etc. But seems something is not compatible.

I made a new install Mojave USB. I am able now to boot into the USB and I completed the Mojave installation. Well I think so but still there is an option to boot from "Boot macOS Install from Prebooter from Preboot" and "Boot macOS Install from Macintosh HD". So I have to boot from USB and then choose Macintosh HD. In verbose mode I get the attached screen. It stops at

IOConsoleUsers: gIOScreenLockState 3....

I have now disabled the RX560 GPU and only running from Intel onboard graphics to make sure it is not a graphics issue.
Anyone seen this issue and have any advice?

## UPDATE ##
I am now able to boot into Macintosh HD (must boot from USB!)and it finished the Mojave upgrade (even though I already did a reinstall from USB). But I seemed to have some unfinished stuff. But it still would not boot before I removed the RX560 and used only internal graphics.

So then I could log in but now is the problem. I can not mount EFI folder from Clover Configurator 5.3.2.0. Mount EFI does nothing. I also tried EFI Mounter V3 and EFI Mounter Pro from Insanelymac. (Operation not supported - error).

How do I mount the EFI folder to change it? Here is what happens in terminal:

Incorrect: sudo diskutil mountDisk disk0s1
Try: sudo diskutil mount disk0s1

Note: Make sure you do not boot in safe mode, as you can only mount /EFI in normal mode.

Thanks @BreBo ,you were right, the reason I could not mount EFI was safe mode. I managed to get a bootable USB and then I could mount the EFI on the system drive. I am not sure really what I did but stripped down everything except my DSDT that I have used some time to get right.

So everything is up and running on OS X 10.14.1 now. This was not straight forward! What a mess. I have upgraded 4 hacintoshes now from 10.13 to 10.14. Every one took me hours of research and troubleshooting

Any hints/tips on getting mojave installed on this motherboard. I appear to be running into a bit of a block and not sure why. Using onboard video card and am trying a unibeast install now to see if I can get this running.

I don't have the GA-270N here now since I built it for a friend. Recently he had no problem upgrading from OS X 10.14.6 to 10.15.2 directly (after I upgraded all his kexts to latest versions first!). In fact never had such an uncomplicated upgrade. If you don't get yours working I could get a copy of the EFI folder with a working DSDT etc. The BIOS setup on the motherboard should be straight forward, make sure that is correct first.
Haha - I see now that this thread was my own, never really got any help, but just writing about it may have fixed it

Here is attached a working EFI folder for GA-270N and running OS X 10.15.2 Catalina. Should work fine also on 10.14 Mojave. Don't forget to change the serial and board number.
