OK, it has downloaded. I hit install, then it tells me to reboot. I reboot and nothing changes?

thanks,

when you reboot, it should have another entry on clover boot screen to Install macOS high Sierra....

Ehh... it says "boot clover from efi""boot clover from efi""Boot macOS from usb""Boot macos from El Capitan(the name of my ssd" and "boot from recovery HD"
 
1. Update your existing Clover install to v4173+ using MultiBeast or official Clover package.

that is the first step. How would i go about doing this?

really appreciate all your help.

you install latest version of clover to your efi, use multibeast to install clover
 
OK. Upgraded to high sierra. No change, still the same glitches. Do i need to find a new GPU?
 
OK, so I ran the script that installs web drivers. But Whenever I restart it changes back to "Default MacOS Graphics Driver" IS there a better way to change to nvidia web drivers?

thanks a lot,
Murray
