Hi Guys,

if select NullCpuPowermanagement.kext boot show xHpet error, i read our topic and disable this.

I Have reinstalled all with standard setting [NullCpuPowermanagement.kext exclude] and PCIRootUID=1, try boot with this but stop booting at the AppleLogo.

Only first boot later my install start and stop at region selection, mouse and keyboard are blocked .

I boot in verbose mode and attach this screenshot.

 

 

 

Tnks a Lot

you may find HPC/High Performance Computing as another term of HPET.

Disable it.

 

can you get in language selection step?

if yes, customize chameleon bootloader and drop down any DSDT.

after install, boot with "-f -v"

you may get KP, don't worry...see the failed item, and disable it in BIOS

repeat until you don't get it again
