Moderators Jake Lo Posted June 4, 2021 Moderators Share Posted June 4, 2021 Mount the EFI partition of the installed drive and place it there. When you format the drive to GUID, it automatically create this hidden partition. Use ESP Mounter Pro.app, OC Configurator or Clover Configurator to mount it.

Moderators Jake Lo Posted June 4, 2021 Moderators Share Posted June 4, 2021 According to your IOReg file, neither of them are loading. Try disabling SMCDellSensor.kext Strange that you don't have at least keyboard working. Link to comment Share on other sites More sharing options...
Alex Kranich Posted June 11, 2021 Author Share Posted June 11, 2021 Now keyboard is working, but touchpad mouse and wifi are not working, i am keeping Catalina OS and updated all with opencore i dont know why but if i install updates, and this mean install big sur latest version, i get error panic. Instead of this, if i dont update kexts in opencore , updating only kext for keyboard . I install big sur as update and in this case boots and i have keyboard and wifi working. but still mouse and touchpad no. I seen that with big sur i have some lag and notebook is not reactive like with catalina. Link to comment Share on other sites More sharing options...
