Mavericks: Native CPU/IGPU Power Management

[toleda]

This issue is related with smbios of iMac 14,2

Same configuration (everything except smbios) with smbios of MacBook Pro 13,2 has a normal speedstep curve.

Not true, macbookpro13,2 has the same problem as imac14,2. CPU PM is not working.

So, I use MacBook Pro 11,2 now. It seems that cpu speed step is all right now.

What does Post #796 say?
How did you conclude SpeedStep is working?

Because Intel power gadge shows nice speed step curve.

So despite the nice speedstep curve of macbook pro 11,2, the PM is still not working? So what should I do?

See post #616 and #619. You said PM was working. The smbios was MacBook Pro 11,2 at that time.

First of all, thanks for your excellent work, toleda.


I've set up native cpu power management and I wouldn't have been possible without your help.


It is working great but I've found something that worries me a bit. The stock settings for Intel SpeedStep are a bit heavy in terms of ramping up the CPU freq. It stays most of the time at the higher clocks with a consequent effect on temperatures.

Is there any way I can force the system to not to ramp up so freely and be more conservative over this?

Thanks in advance!

Evidence? What should it look like?

Hi,

Wanted to say this tutorial was dead on and been using it since Mavericks.

I currently did a fresh install to 10.11 El Capitan and wondered if this guide can / would be updated for 10.11?

Concern on my end is not being able to install required Kext into S/L/E due to El Cap Restriction. Would this process still work if Kext was installed into Clover / Kexts?



Any information would be greatly appreciated and thanks for your time

XPCM works the same in 10.9, 10.10 and 10.11. Skylake requires an update.
AICPUPMI works from EFI/CLOVER/kexts/10...
Only requirement for 10.11 S/L/E is disable SIP, restart, install kexts, rebuild cache, enable SIP, restart.
