  1. @Rajganesh I'd rather do a clean install than upgrade. But it's up to you. I think it should work.
  2. macOS starts loading, then the screen goes dark. But when you bring a light close to the screen, you can see that the system has loaded normally. After a few minutes the backlight returns to normal. Edit: I managed to solve the problem using bootarg "-igfxblr". Attached is my final EFI. Thanks for the help. EFI.zip
  3. @Jake Lo yes! When i was on Bigsur it happens with the whatever green after version 1.4.5
  4. @Jake Lo It works! But the screen backlight is off when the installation screen loads. Then after a few minutes the backlight comes back on. How do I fix this problem? I managed to install successfully! all that's left is to solve this little problem. Thank you very much in advance.
