I have a few kexts in EFI/CLover/kexts/Other
Lilu

I had placed them there on the USB drive when I installed Mojave. So, I video card worked (except for the displayport).
I have copied the folder to the hard drive and I can boot into Mojave.
The mouse and keyboard seem to lock up periodically, necessitating a hard reboot, I don't know why. Previously, I tried Multibeast for post install and I don't think I had that mouse problem.
Wonder if it had installed some patch?
Anyhow, I want to fix shutdown, so I am going to make some changes and see if it works. Perhaps I should wait until everything works the way I want before installing the kexts to the library/extensions folder and removing them from Clover?
