try without CpuTscSync.kext

no change!

Ok, with this after disabling FakePCIID_Intel_HDMI_Audio.kext, I don't have the freezing problem anymore but the performance is not good, CPU load is always more than 15% and the fan is high all the time.

what can be the problem?

look into using CPU Friend kexts, different options..

CpuTscSync is still enabled

didn't think SSDT-PMC.aml was needed on a skylake system....

Ok, after setting SMBios to iMac 17.1 the CPU load problem was solved but HDMI doesn't work anymore, any comment?

using a desktop smbios on a laptop is wrong

I changed smbios back to MacBook Pro 13,3 and the load problem got solved itself, I don't know how!! but the HDMI problem was because of disabling EGPU, I removed the flag to disable EGPU and now HDMI is working well, I guess the HDMI is wired through EGPU...! anyway I attached my EFI (don't forget to enter a valid serial number)

I just noticed when I don't disable EGPU, the laptop's LCD backlight control stops working, what can I do?

SSDT-PMC.aml is probably not needed

MacBookPro13,1 is a better choice

but MacBookPro13,3 has the exact CPU?!

BTW, I changed the smbios and disabled the SSDT-PMC.aml, nothing changed!
