    macOS Native CPU/IGPU Power Management

    I guess IPG is confusing because the frequency shows almost flat around 2900 when it's idling and doing nothing, I presume this is when (8) would be selected in AppleIntelInfo. IPG never shows the frequency at 800 MHz. This is why I've assumed power management wasn't working properly. Anyway...

    macOS Native CPU/IGPU Power Management

    Original post New files attached, thank you. I can see in ioreg with iMac 14,1 SMBIOS selected GFX0 is not there anymore, this makes sense because that real mac does not have a discrete gfx card in it, whereas 14,2 and 14,3 do. I should have realised this sooner...At least that is cleared...

    macOS Native CPU/IGPU Power Management

    Still not booting with KernelPm off and iMac14,1 SMBIOS. Please note the CPU I am attempting this with is i5 4570S. I have another hack with i7 4790K and like you I can boot that without using KernelPm. Is KernelPm required to be off to get native pm working? Can you tell me specifically...

    macOS Native CPU/IGPU Power Management

    I tried but system will not boot without KernelPm, presumably because my CPU is Haswell and it has a locked MSR, as shown in the bootlog.txt I attached with my files zip.

    I followed the guide exactly. I rebooted between doing the baseline test and the pm tests as instructed in the guide. My zip includes new files for both baseline and pm.

    macOS Native CPU/IGPU Power Management

    Ok, which kext are you referring to? More importantly, is this anything that I need to fix and is power management working? I've done a lot of research but it's very hard to find answers about these things and know whether it's up to date information or not. I appreciate you are doing this out...

    macOS Native CPU/IGPU Power Management

    Ok, I have done a fresh install running 10.13.1 and re-run the tests, files attached. Running kextstat I can see LPC is loading using the 9-series SSDT in /patched. One thing I have noticed is there is always a GFX0 entry showing alongside IGPU in ioreg under AGPMController even though the...

    macOS Native CPU/IGPU Power Management

    I'm confused, you said I shouldn't be using the 9 series SSDT with an 8 series motherboard in your last reply to me, which makes sense, but now you are saying I should?? I've already uploaded the files generated when using the 9 series ssdt, they are in my original post.

    macOS Native CPU/IGPU Power Management

    Done. Done. Setting up two machines and got confused, other is 9 series whilst this is 8 series. Have removed the 9 series ssdt. It's not clear from the guide where to get the 8 series SSDT and in fact if it is needed at all. Can you tell me where I can get it if it's needed, please? I have...

    macOS Native CPU/IGPU Power Management

    Description of problem Not sure whether PM is working properly. Without it added, Intel Power Gadget shows the cpu speed changing under load. With PM config the cpu speed seems to default to top speed and then drop when running Geekbench, before returning to top speed when completed. FWIW -...

    Anybody with the "Essentials.pkg" Error

    This was happening to me but I got around it by removing 1 x 8GB stick of RAM leaving 1 x 8GB still in. The thing is, I managed to install in this machine without a hitch before but used windows as I had problems with display resolution on a new super wide monitor. I tried to boot into...

    2560x1440 resolution HD4600

    I'm having the same problem. I have: 4790K Z97-d3h LG25UM65-P The motherboard only outputs above 1080 on the HDMI port. The monitor accepts 2560x1080 on all inputs (HDMI, DVI, D-PORT). I only get 1080p option in Displays preference pane, but that sets the display to 1920x1080 meaning it...
