I am trying to install Catalina using OpenCore but I am facing some issues:
1. After the selection and all the visual text loading I get black screen instead of the Apple logo.😥

I though that there was failure in the Installation and after lots of attempts I left the computer to do it's things and then the computer enter to sleep mode and when I woke it up,

2. When the computer woke up and finally I got an image on my screen the mouse and keyboard are not working😩

Please help meeee
I am on this setup for months.
