What CPU do you have?

Please provide complete details in your profile/signature
(Profile/Settings link in upper right corner of this site)

System: manufacturer/model
CPU: detailed CPU model + motherboard chipset
Graphics: all graphics devices + laptop internal screen resolution

For example, typical Ivy laptop:
System: HP ProBook 4540s
CPU: i5-3320m/HM76
Graphics: HD4000, 1366x768

Use CPU-Z on Windows to find CPU (Core iX-xxx) and motherboard chipset (HMxx), and graphics capabilities. For a laptop, these details are important and affect critical installation procedures.

A question: can I edit "i5-3317U,17,0,1700,2600,2,4" in the ssdtPGen sh inside the probook installer using Pacifist?

Try setting APLF to zero in your SSDT.aml.

Not really, but you have to use pkgutil to extract the files from the package, do the edits, then use pkgutil to make it back into a modified pkg. Not sure why you would do that though...

I search how to setting APLF to zero....
I'm not sure how works the ssdt generator but i believe that use flags that works fine in the probooks and on my build.

Open the SSDT in MaciASL and it will be obvious.

APLF to Zero give me a AICPUPM KP
I try again with a fresh install and go step by step.

Not surprising really. I'm certain we are missing some important details in the PM puzzle.

Did you try with -xcpm?
