I just installed High Sierra on my P55-US3L 1.0, i5 750 and GT 640
All went well but SpeedStep didn't work
I read some posts and:
- deleted NullCPUPowerManagement.kext from EFI partition
- Enabled "Drop OEM"
- Enabled "Generate PStates"
- Enabled "Generate CStates"
Hi. I have and old box with P55-US3L + i5 750 + Intel SSD 240Gb
I used Mac Mini with Sierra to build a bootable USB (with the latest Unibiest) with High Sierra installer
I changed BIOS (no UEFI here) settings for AHCI, disabled XHD.
Clover boots fine
Installer boots fine
But there are no...
