Testing the waters on my new Z170 build based off the entry level board and the Intel 6th gen i7-6700K. I was intending to complete the build, have it up & running smoothly before beginning this post. But I've run into problems where no amount of reading into Pike R. Alpha's post nor Google is helping. So here I am.
Reading around I got to downloading the 10.11.4 from Apple cause the Skylake build it appears needed that. Made the bootable with Clover-on-it-USB.
Clover strangely would not install. Showed complete progress but at the end I had no EFI partition mounted on my desktop which meant it was not okay. Naturally I was doing a UEFI only install. Learnt of needing to run "nvram -c" command in the terminal without quotes and the command to format the EFI partition as FAT32 & repeated the process & it succeeded.
Now I had the Monitor (LP2065) connected via DVI to the onboard video. I got the display on BIOS and the first thing I did was to flash latest F7 BIOS. Rebooted and set the values I thought were okay.
Among the new ones was the APIC numbered setting that I disabled. But as I later found enabling did not change anything. I already had few edits in the config.plist. (a.) The patch for USB port limit (b.) Skylake graphics patch (c.) IOGraphicsFamly patch (for taking care of the second stage glitch).
In verbose mode the USB Stick booted right up. It was throwing a few unfamiliar messages but the installer booted okay. Without much fuss I had the Samsung 850EVO connected and so installed on it. Went through quite fast compared to my older install on Z97-4790K system.
Rebooted SSD and installed clover on it & it worked right away.
Time to look into the Power Management side of things.
the ssdtprgen Beta script downloads and works and also makes a SSDT.aml file. But the thing appears to do nothing. I placed it in ACPI patched and rebooted. Checked with the Intel Power Gadget idles at about 1.6 Ghz (1.51 Ghz to be lowest) at 25º C. Loading the CPU with the dummy yes command in terminal (single instance) takes CPU to 4.0 Ghz with temps at 40º and 6 more instances make the CPU reach 55º. Subsequently killing all yes instances bring CPU idle back to 1.57 Ghz.
So I tired to install plugins to FaleSMC (HWSensors) and used Istatmenus. It showed identical values. I believe HWmonitor would too since I have seen it behave similarly in the past.
Next option left to check was the AppleIntelInfo kext from Pike R. Alpha. Here is where I get lost The thing does not output anything in the terminal or the console. I swear in the early days of building the 4790K system I had the results in terminal. Now nothing. No error messages nothing.
So as things stand - power management is incomplete. System idles at 1.5 Ghz instead of 800 Mhz and turbo boosts to 4.0Ghz. at least what IntelPowerGadget V 3.0.3 tells me. The presence of SSDT does not change anything. But speed stepping is working regardless of its state in the BIOS, enabled or disabled..
So friends any ideas?
