Hello,
I have successfully installed Mojave on my old Desktop Computer with the following specs:
Motherboard: MS-7613
CPU: i3-540
RAM: 4Gb
GPU: integrated, old Intel HD Graphics
DISK: SSD Kingstone 120Gb

I used the patched version of Mojave provided by dosdude.

Since Mojave prompted me to update to Catalina, I tried to do so, and the installation when smoothly, but unfortunately now I can no longer access MacOs as I get stucked at:

IOConsoleUsers: gIOScreenLocked State 3

I also tried to change the config.plist to a generic one for Catalina but I'm stuck in the same place.

I would like to try and fix this situation, I have understood that the problem lies in the GPU, but I really don't know where to start.

Hope you can help me :)

I will attach the working plist for Mojave and the one I tried to use for Catalina.

If you want to run Catalina you must use supported hardware.

Hi! Thank you for your reply. Is my thread violating the rules of this forum?

Hello friend, remember that in order for this error to be solved, you must download and place the FakeSMC kext in "other".
I use Catalina today with this processor, and for me to start, put that kext and it worked.
In my case, I had the error finishing the installer and starting the first time. That way I was able to fix it.
Greetings from Argentina, excuse my English
